DALY LiFePo4 4S 12.8V 40A BMS with Temperature Sensor (Waterproof)

Description

4 Series 40 Amp BMS for Lithium Ferro Phosphate batteries 4×3.2Volt = 12.8V (Nominal Voltage) with Temperature Protection NTC Sensor. The LiFePO4 Batteries are 3.2V hence it needs a BMS built for that. A BMS is battery management system that monitors battery health and disconnect the battery during unsafe working conditions like overcharge, over discharge. This BMS has NTC (Thermistor) for temperature protection.
