Yunseity 14S 48V 40A Li ion Battery Protection Board, Cell BMS PCB Board Module with Balance, for Lithium Ion, Polymer

The difference between the split port and the same port: the split port: when charging and discharging, the positive and negative poles are separated; the same port: charging current is the same as the discharge current, and charging and discharging are in the same place. Without balance and balance: balance: when the high-voltage battery is discharged with a resistor, waiting for the low-voltage battery to charge the voltage to achieve the same voltage and improve the performance of the whole battery. Function: The board has short circuit protection function, overcharge protection function, over discharge protection function, balanced voltage function, low conduction internal resistance functions. SApplication: uitable for lithium batteries with nominal voltage 3.7V 10-14 strings. Applied to rechargeable lithium ion battery, lithium ion polymer battery. Premium quality: It adopts high current and high withstand voltage discharge MOSS. The internal components are brushed with three anti-adhesive (waterproof, anti-static, anti-interference), stable ans reliable quality.
