3S 100A BMS LED Heatsink Li-ion Lithium Battery Balance Charger 3s 3 Cell 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 2.7V - 4.2V lithium battery (18650, 26650, LiPo, Li-ion)Charging input voltage: 12V - 12.6VMaximum starting current: 100ADischarge current: 100A Charge current: 60ABoard Size: approx. 42*60*7.4mmPackage includes: 1 x Lithium Battery Protection Board 3S 100A BMS LED Heatsink Li-ion Lithium Battery Balance Charger 3s 3 Cell.
