Emergency treatment of water entering the electric skateboard battery while riding
Welcome to the page – Emergency treatment of water in the electric skateboard battery while riding.
In this chapter, we will introduce you to 4 methods and 6 inspections of emergency treatment, as well as professional advice from PROPEL EV.
So, if you are looking for relevant solutions, this chapter is for you.

1.1 Stop riding
If water enters the battery of a skateboard while riding, it may cause the skateboard to suddenly lose power, make abnormal motor sounds, significantly reduce speed, or have slow control response. Once water is confirmed, you need to take the following measures immediately:
Pull over: Make sure you are in a safe area to avoid accidents caused by losing control of your skateboard.
Power off: Immediately turn off the skateboard to prevent short circuit or further damage to the battery.
Unplug the battery: If possible, wipe off any moisture on the surface before removing the battery to reduce the current circuit.
When the battery cannot be removed in time, you can take the following emergency measures:
If you do not have the right tools to remove the battery on site, place the board in a dry place and tilt the board to make the water ingress point downwards to facilitate water outflow and reduce further penetration. In the mean while, ask for help as soon as possible and contact professional maintenance personnel for further assistance.

1.2 Cut off the power of the electric skateboard battery ASAP
If conditions permit, quickly disconnect the battery from the electric skateboard to prevent a short circuit. To ensure that the power is completely turned off, you also need to:

Check various interfaces: For example, check whether there are any water marks on the charging port, the connector between the controller and the battery. You should also check the battery for obvious signs of water intrusion, such as water stains, odors, or leakage. You also need to touch the battery case to see if it is hot to avoid danger caused by internal short circuits. Regardless of whether you find moisture on the connector or around the battery, you should immediately turn off the board before making any judgments.
Caution!
Natural cooling: Place the battery in a ventilated and dry environment to cool naturally. Do not try to use high-temperature equipment (such as a hair dryer or heat gun) to heat and dry it.
Drain and dry: If you suspect water has entered the battery, try gently tilting the battery to help the water drain out of the surface and use a desiccant to absorb moisture.
Observe the appearance: Check whether the battery is accompanied by abnormal phenomena such as bulging, leakage or odor. If these phenomenas exist, it means that the battery may be seriously damaged inside. If the heating condition is not relieved or the abnormal phenomenon intensifies, the battery may subsequently catch fire or explode. At this time, the battery should be isolated as soon as possible, placed in an open area (or in a water tank to cool down), and away from flammable materials. At the same time, professional maintenance personnel should be contacted and emergency measures should be taken to prevent the accident from escalating.

1.3 Drying and inspection
There are many ways to dry the electric skateboard batteries, but it should be noted that due to different water quality, the impurities remaining in the water after drying will cause different degrees of damage to the batteries. Therefore, when the battery is soaked in water and dirt appears, it is recommended that you contact a professional directly for repair to avoid secondary damage.
For the case of slight water ingress and very clean water quality, we have compiled the following methods for your reference.
① Natural drying
Place the battery in a dry, well-ventilated area away from direct sunlight. You can tilt the battery to help moisture flow out. Make sure the contacts are facing down to prevent moisture from being trapped.
Advantages: Simple and easy, no additional equipment required. No thermal damage to the battery.
Disadvantages: The drying speed is slow, which may take more than 48 hours. It is also highly dependent on the humidity of the environment, and a humid environment will make the drying effect worse.
② Use desiccant
You can use silica gel desiccant, activated carbon or rice as desiccant. The specific method is to put the battery into a sealed container (such as a plastic bag or sealed box), and then add an appropriate amount of desiccant. Let the battery and desiccant stand for at least 24 hours, preferably 48 hours, to ensure sufficient moisture absorption.
Advantages: It can dry quickly and effectively, reducing the risk of battery damage.
Disadvantages: You need to purchase desiccant separately. If the desiccant is used improperly, it may not completely absorb moisture.
③ Use equipment to dry
In addition to the above two methods, you can also use equipment to dry the electric skateboard battery. For example, you can put the battery in front of a fan and let the fan blow continuously to increase air flow (do not blow directly at the battery, which may cause local overheating). Alternatively, place the battery in a professional low-temperature dryer and set the temperature below 40°C to ensure that the battery’s safe temperature range is not exceeded (never use high-temperature drying or direct heating (such as a hair dryer, oven, etc.), which may damage the battery and even bring the risk of fire and explosion). If you are in an environment with high humidity, you can use a dehumidifier to reduce the humidity of the surrounding air, thereby speeding up the battery drying process.
Advantages: It can dry quickly and effectively, reducing the risk of battery damage.
Disadvantages: It requires additional equipment purchase and standardized and continuous operation. Improper operation may cause irreversible losses.
④ Battery disassembly
If you are familiar with the battery structure, you can carefully disassemble the case and clean the internal components to speed up the drying process. But this requires relevant professional knowledge and is not recommended for ordinary people.
Advantages: Ability to thoroughly clean and dry internal components so a professional can better inspect the battery condition.
Disadvantages: This method requires expertise and tools. People without expertise may damage the battery again or cause risks during operation.
Caution: Regardless of which method you use, make sure you give the battery enough time to dry. Allow at least 24 hours, preferably 48 hours, to ensure that all moisture has evaporated.
It is very important to check the battery after it is dried. This determines whether the battery will suffer secondary damage. We recommend that you refer to the following steps.
① Appearance inspection
Check for water marks: Carefully inspect the battery case and related contact points to ensure there are no obvious water marks or drops, wipe with a tissue and check for any signs of moisture.
Check for residue: Look for signs of moisture or mold on the battery, especially in the sealing area.
If conditions permit, carefully disassemble the battery casing and check whether there are any water drops or moisture inside. Pay special attention to whether the insulating material (such as foam or plastic) is wet. After disassembly, gently touch the internal circuit boards and connectors to make sure there is no moisture. Use high-concentration alcohol to clean the circuit contacts and connectors to ensure there is no corrosion.
② Touch test
Touch the battery: Gently touch different parts of the battery to make sure the surface temperature is normal.
③ Odor inspection
Smell the battery to check for any unusual odors (such as burning or chemical). No odor usually means the battery is in good condition.
④ Voltage test
Using a multimeter, measure the battery voltage to make sure it is within the normal range (and in accordance with the battery specifications). Also compare it with the battery’s nominal voltage to make sure there is no significant difference.
⑤ Charging test
Connect the charger: Try to connect the battery to the charger and observe whether the charging indicator is normal. Pay attention to any abnormalities during charging (such as overheating, smoke or abnormal noise).
⑥ Discharge test
After confirming that the charging is normal, let the electric skateboard idle to discharge, and pay attention to whether the battery has performance degradation or malfunction.
The above steps can be used to determine whether the battery is completely dry. If any abnormalities are found during the inspection, it is recommended to seek help from the brand for further evaluation.
1.4 Professional cleaning advice
As a brand, we do not recommend disassembling the battery, as it may cause damage to the electric skateboard battery without relevant professional knowledge. At the same time, since disassembly operations are difficult to achieve comprehensive cleaning and maintenance without professional equipment and system knowledge, hidden dangers may still remain.
But we understand riders’ concerns very well, so now we will use PIVOT’s battery as an example to focus on the cleaning part.
① First of all, when we designed the PIVOT battery, we took into account the possibility of water entering, so it has an independent case packaging on the outside, which makes it waterproof to a certain extent.

② We can open the battery pack by removing the screws on the battery case. In order to protect the electronic components of the battery, they are covered with insulating paper. If you find that the insulating paper has been completely soaked after the battery has been flooded, it is recommended to send it directly to a professional for repair, because this means that your electronic components are already facing water erosion.
③ If the repair time is long and the distance is far, you can open the protective layer and wipe all electronic components with cotton swabs and alcohol. In addition, you also need to tear off the insulating paper on the side of the battery and observe whether there are water stains or rust marks on the positive and negative spot welding positions of the battery. When wiping, please use high-purity alcohol to prevent accidents caused by conduction. This process will test your professionalism, patience and environmental conditions, so please do it carefully. The battery will be directly damaged if you are not careful.

1.5 Professional maintenance

If the skateboard malfunctions due to water in the battery (such as failure to start, light failure, unstable speed), it is recommended to send it to a professional battery repair station for repair. Do not try to repair a damaged battery or circuit by yourself to avoid safety issues.
Chapter 2:
Emergency treatment if the electric skateboard battery is found to be damp before riding
If you unfortunately find that your electric skateboard has been damp before riding, please don’t be discouraged.
In this chapter, I will use 5 emergency treatment methods and 4 inspections, as well as how to prevent it, to help you recover the loss to the greatest extent.
Please check.

When the electric skateboard battery is damp, please do not connect it to the power supply to prevent short circuit or irreversible damage. If you connect the power supply by mistake, please refer to the “Emergency treatment of water entering the electric skateboard battery while riding”, and give priority to protecting the safety of the battery.
2.1 External Cleanup
Wipe the surface: Use a dry cloth to clean the moisture on the surface and joints of the skateboard.
Check the wheels and motor: Make sure the wheels rotate smoothly and there is no water inside the motor.
After the battery is dry, you need to re-lubricate and maintain the bearings, motors, gears, and hubs.
2.2 Drying and inspection
Battery moisture is usually not as serious as water damage, but due to the influence of the length of time it is exposed to moisture, it will usually cause damage to bearings, gears, belts, motors, controllers, batteries, circuit boards and screws. It is recommended to perform maintenance and replacement after drying according to the actual situation.
Before drying, please remove the deck away from the board and disconnect the power supply. Carefully check the battery case, controller, wiring ports and circuit boards to confirm the degree and location of moisture. Use high-purity alcohol to clean the contact points of the circuit to ensure that no corrosion remains. Touch the battery and circuit parts to ensure that there is no obvious moisture (if you find that the battery is abnormal, please contact a professional for replacement or repair. Do not disassemble or repair it without professional skills).
We recommend that you refer to the following methods for drying.
① Natural drying
Place the skateboard in a well-ventilated area away from direct sunlight. Tilt the skateboard to help moisture drain naturally. Disassemble the battery case, take photos of the wiring sequence, and separate components such as batteries, motors, and circuit boards as much as possible to speed up drying.
② Use desiccant
Place the disassembled components in a sealed container, use silica gel desiccant or other moisture-absorbing materials, and let it sit for more than 24 hours.
③ Use a fan to dry
Place the skateboard in front of the fan and turn on the fan to speed up the air flow and help the moisture evaporate. Make sure the fan is blowing directly at the wet parts, except for the battery.
④ Water absorption treatment
Use lint-free cloth or absorbent paper to gently dry the external moisture. Pay attention to the operating force to avoid excessive force that may damage the corresponding components.
⑤ Long-term static
After taking the above measures, leave all components alone for at least 24 to 48 hours to allow the moisture to evaporate completely. During this time, do not try to start or charge the skateboard.
After the rest, check whether all components are completely dry, especially the battery, motor, controller and circuit board. Please refer to the following order for inspection.
① Battery inspection
Check for water marks: Carefully check the battery case and contact points to make sure there are no obvious water marks or water drops, and wipe them with a tissue to see if there are still any signs of moisture.
Check for residue: Look for signs of moisture or mildew, especially in sealed areas.
If conditions permit, carefully disassemble the battery case and check if there are still traces of water droplets or moisture inside. Pay special attention to whether the insulating materials (such as foam or plastic) are damp. After disassembly, gently touch the internal circuit board and connectors to ensure that there is no moisture. Use high-concentration alcohol to clean the circuit contact points and connectors to ensure that there is no corrosion.
Touch the battery: Gently touch different parts of the battery to make sure the surface temperature is normal.
Odor check: Sniff the battery to see if there is any odor (such as burnt or chemical). No odor usually means the drying condition is good.
Voltage check: Using a multimeter, measure the battery voltage to make sure it is within the normal range (and in accordance with the battery specifications). Also compare it with the nominal voltage of the battery to make sure there is no significant difference in the voltage value.
Charging test
Connect the charger: Try to connect the battery to the charger and observe whether the charging indicator is normal. Pay attention to any abnormalities during charging (such as overheating, smoke or abnormal noise).
Discharge test
After confirming that the charging is normal, let the electric skateboard idle to discharge, and pay attention to whether the battery has performance degradation or malfunction.
The above steps can be used to determine whether the battery is completely dry. If any abnormalities are found during the inspection, it is recommended to seek help from the brand for further evaluation.
② Controller inspection
Carefully check all the controller connection ports to make sure there is no moisture left. Next, use a multimeter to check the solder joints, contacts and components on the controller to confirm any damage, and then make sure all connectors are plugged in tightly. After confirming that the controller is dry and undamaged, reassemble the board, connect the power supply and perform a functional test to check that the controller is working properly.
③ Motor inspection
Check for water marks and carefully check all the motor connection ports, paying special attention to the motor contacts and connectors to make sure they are dry. You also need to observe whether there are obvious signs of moisture or humidity inside.
Use a multimeter to check the voltage of the motor to ensure that the current path of the motor is normal.
Check the resistance of the motor windings to confirm that there are no short circuits.
After confirming that the motor is dry, connect the power supply to perform a functional test. Pay attention to the sound and vibration of the motor when it is running to ensure that there are no abnormalities. In actual use, pay attention to the performance of the motor to ensure that there is no overheating or malfunction.
④ Circuit board inspection
Examine the exterior of the circuit board, looking for signs of water stains, corrosion, or discoloration. Pay special attention to solder joints and connectors as well as the underside of the circuit board and around components to make sure they are dry.
Use a multimeter to check the solder joints and connected resistors on the circuit board to confirm that there is no short circuit. After confirming that it is dry, reconnect the power supply and perform a functional test to check whether the light is on normally, and pay attention to whether it flickers or does not light up.
