1S 5A 3.7V BMS PCM PCB Li-Ion Charging & Protection Module with Nickel Strips

Electronic system protecting 1S battery against discharging and at the same time a charger for these batteries. It allows you to build a safe battery pack that does not need to be charged with special Li-ion chargers. The 2 in 1 module will keep the cells in the best conditions, preventing them from overcharging and over-discharging. One module replaces the charger and the security module here. Product features Short circuit protection. Overcharge protection. Over-discharge Protection. Overcurrent protection. They can be used for various 3.7V / 3.6V lithium cells. Compact dimensions and low weight Ensure safe use of the battery Technical data Maximum charging voltage: 4.25 ± 0.05V (per cell) Minimum discharge voltage: 2.45 ± 0.05V (per cell) Max. charging / discharging working current: 5 A Overall dimensions: 92 x 4 x 2 mm Blade length: 33 mm
