Product Description
This product is a low-power battery pack protector designed for primary protection of 3 series-connected lithium-ion/polymer rechargeable batteries with balancing. However, the balancing current is limited to just over 20mA, which is only used to eliminate errors between cells and prevent voltage differential accumulation over long-term cycling. Large differences in battery capacity cannot be compensated by this type of dynamic balancing. Professional active balancing is required.
Notes:
1. Before purchasing, please check the voltage of each battery cell to ensure it is normal! Replacing the protection board will not work if the battery is abnormal. Soldered batteries are not returnable or exchangeable!
2. Before installing the protection board, carefully check that the positive and negative poles of the battery match the positive and negative poles on the protection board. Connecting the protection board incorrectly will damage the module!
3. Lithium battery protection boards cannot be used with lithium iron phosphate batteries, xenon lamps, high-power hand drill battery packs, electric fishing machine battery packs, electric bicycle battery packs, children's car batteries, or products with motors or motors. Customers purchasing these combinations should take note!
4. Always charge the battery with a charger specifically designed for lithium batteries. Never use a lead-acid battery charger. Lead-acid batteries may cause high voltage to break down the MOSFET on the protection board, causing the protection board to overcharge and fail to protect. Polymer battery charger voltage = number of battery strings x 4.2V.
