Description: The BMS is a separate port/connection model, the charge source and output have individual connections. If a common port BMS is needed please see this link https://www.ebay.com/itm/184567779219 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. This model uses an incredible heatsink for intense operation and reliability. A new generation of MOSFET (AOD472) has been added to the BMS to increase pulsed amp current capability to over 100A. Battery compatibility: Voltage of 2.5V - 4.2V lithium battery (18650, 26650, LiPo, Li-ion)Charging input voltage: 12V - 12.6V(Max)Maximum starting current (<1s): 100ADischarge current (sustained): 40A/60ACharge current: 10ABoard Size: approx. 41*62*7.4mm Package includes: 1 x Lithium Battery Protection Board1 x Wiring Instruction Guide Condition is New.
