3Series 12V 15A Li Ion Battery 18650 Charger BMS Protection Board (with Balance)

Features: Protection circuit board is the heart of battery pack, must to have to avoid battery pack from explosion, fire and damage. It will protect battery pack from overcharging, over discharging over current and short circuit. The protection board with balance has equilibrium function to keep each cell in balance and good service life. Choosing the correct protection board and applying it appropriately is vital to the longevity your batteries. Quiescent current less than 30uA, so power consumption is small. Specifications: Type(Optional ): without balance, with balance Model: HX 3S FL20(without balance) ,HX 3S FL25A A(with balance) Size: without balance:58 *20 *3.6mm 2.28*0.79*0.14inch with balance: 56*45*4.0mm 2.20*1.77*0.16inch Over voltage range: 4.25 4.35v+ 0.05v Over discharge voltage range: 2.3 3.0v+ 0.05v Maximum operating current: 15 A (without balance),0 15A(with balance) Maximum transient current: 20A(without balance), 20 25A(with balance) Quiescent current: less than 30uA Internal resistance: less than 100m Ohm Charging voltage: 12.6v 13V Working temperature: 40 +50 celsius Storage condition: 40 +80 celsius Effective life: >30000h Short circuit protection: Yes, delayed self recovery Balance current(with balance): 45mA The component included: without balance: 1 pcs 2110 CB protection chip, 2 pcs AOD472 with balance:1 pcs 2110 CB protection chip, 1 pcs BB3A ,4 pcs AOD472 AOD452 Test point instructions(with balance): S1 S2 short circuit P + P will output voltage, indicating that all MOS protection is normal, adding a constant temperature detection can extend the temperature protection function. Package Included: 1 x PCB Protection Board(have assembled) Note: 1.Do not mix the good battery and poor battery to use. 2.The internal resistance of 3 battery capacity are closer will be better. 3. Please buyers know the professional knowledge of this module before buying.
