BMS 5S 21V 80A 90A 18650 Li-ion Battery Protection Circuit Charging Board Module
Features:
1.This product uses 5 dedicated lithium-ion battery ICs as processors to detect real-time information such as voltage, charging and discharging current, and environmental temperature of each battery,
2.Implement overcurrent protection functions for overcharging, discharging, and discharging batteries;
3.It has protection functions such as short circuit, charging overcurrent, temperature protection, etc;
4.The board has good quality and is equipped with thick copper hardware terminals, making it durable;
5.It does not generate heat after long time use, and is commonly used for battery pack of lithium Angle grinder of Makita model.
