4S 100A 12V 16.8V Li-ion LiPo Lithium BMS LED Heatsink Battery Balance Board Note: This BMS is for Li-ion LiPo Lithium batteries. LiFePO4 based BMS boards are in my other listings. Description:This BMS balance board is used for a lithium battery pack to equalize voltage and protect the cells. This module charges, discharges, balances, and acts as a low voltage/over charge cutoff. There are 2 options to wire the BMS. The first option uses the COMMON Port for both charge and discharge at 60A. The second option, uses a SPERATE Port for charging (60A) and discharging (100A), requires an extra solder point but is worth the added output. Battery compatibility: Voltage of 2.5V – 4.2V lithium battery (18650, 26650, LiPo, Li-ion)Charging input voltage: 16.8VMaximum starting current: 100ADischarge current: 100ACharge current: 60ABoard Size: approx. 42*60*7.4mmPackage includes: 1 x Li-ion Battery Protection Board Condition is New.
