What are the methods to restore the imbalance of the lithium-ion battery?

1. First charge the entire battery pack, and then float for 2 to 3 hours after turning the light. If the battery pack is left under power for a long time and cannot be charged, you can directly charge it for 10 minutes (using the discharge port), and then charge it normally. 2. Unplug the cable of the protection board. Before unplugging, please make a mark. For the board with 2 cables, the cable cannot be reversed. Measure the voltage of the adjacent pins on the cable. If it is 48V, there are 16 voltages, and 60V is 20 voltages. The first string voltage from the negative pole is the voltage from the negative pole of the battery pack to the first cable, and so on. Find the single string with voltage lower than 3.50V, judge the positive and negative poles, and mark them. 3. Use a 3.6v charger to charge a single string with a voltage lower than 3.50v to 3.60 to 3.70V. However, someone must be on duty to prevent the battery from being scrapped due to overcharge. 4. Insert the flat cable back in the original order, pay attention not to reverse the connection, install the battery, and then put it into use. Finally, I will teach you some ways to usually maintain lithium-ion batteries. Due to the memoryless characteristics of lithium-ion batteries, the battery pack should be charged regularly every time or every day after riding; if the lithium-ion bicycle is left for more than two months, the battery pack must be thoroughly charged. Charging; if it is left for more than 5 months, a charge-discharge cycle should be performed; when the lithium-ion bicycle is not in use, the power should be turned off in time, or the battery pack should be removed from the battery holder. Because the motor and controller will still consume power in the no-load state. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
