4S - 16V - 6A - BMS PCM PCB Module for Charging and Protection of Li-Ion Cells - for 18650 Cells

Electronic system protecting Li-ion batteries 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 lithium cells. Compact size and lightweight. Ensure safe use of the battery Technical data Maximum charging voltage: 4.25-4.35v ± 0.05v Minimum discharge voltage: 2.3-3.0v ± 0.05v Max. working current: 4-5A Max. peak working current: 6-7A Working temperature: -40 --- + 50 Storage temperature: -40- +80 Quiescent Current: 6uA Internal resistance: 45 mOhm Dimensions: 67 * 16 * 1.0mm
