Electronic system protecting 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 Compact size and lightweight. Ensure the safety of the battery Technical data 10.8V (3.6V * 3S) lithium batteries and accumulators 11.1V Lithium Batteries (3.7V * 3S) 12.6V (4.2V * 3S) lithium-ion batteries Over charge protection: 4.25-4.35v ± 0.05v (per cell) Over-discharge protection: 2.3-3.0v ± 0.05v (per cell) Working current: 8A Module dimensions: 31x32mm Weight: 2.5g https://elecena.pl/product/22620571/3s-8a-12v-bms-pms-li-ion-charging-balancer-protection-module 2023-02-22 https://elecena.pl/product/22620571/3s-8a-12v-bms-pms-li-ion-charging-balancer-protection-module 2025-10-29
