Equipped with balancing function, but with a balancing current of only over 20 mA, it can only be used to eliminate the accumulation of synchronous cyclic voltage difference. Excessive differences in quantity cannot be compensated for through passive equilibrium. This requires professional proactive balancing to handle.Notes:Before purchasing, please check if the voltage of each section of the battery pack is normal! Replacing the protective board is useless even if the battery is not functioning properly! Welded ones cannot be returned or replaced!2. Before installing the protective board, please carefully check whether the positive and negative poles of the battery can correspond to the positive and negative poles on the protective board. If the positive and negative poles of the protective board are connected incorrectly, it may cause damage to the module!3. The lithium battery protection board cannot be used for lithium iron phosphate batteries, hernia lamps, high-power hand drill battery packs, electric fishing machine battery packs, electric bicycle battery packs, children's car batteries, most likely electric motors or products with electric motors. Customers who purchase the above combinations are advised to pay attention!4. The battery must be charged with a lithium battery specific charger. Do not use a lead-acid battery charger, as lead-acid charging may cause high-voltage breakdown of the protective board MOS tube, resulting in the protective board being overcharged and not protected.
