14S 48V 15A Battery Charging Module PCB - BMS Protection Board For 14 Series lithium LicoO2 Limn2O4 18650 battery - With Balance Function - for e-bike (14s 48V 15A)

A battery management system (BMS) is an electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and/or balancing it.

Specification:

• Resistance Inner ≤15 mΩ;

• Self-Consumption Working Current:≤60 uA;

• Sleep Current (when Over-discharge): ≤10 uA;

• Working Temperature Range: -30/+80 ℃

Attention When Connecting:

• When we connect BMS with cells or disassemble BMS from the battery pack, the following order and regulations must be complied with to avoid damage to components of BMS and problems of not protecting cells.

• In order to achieve the best performance of BMS and to run the longest distance, all the battery must be matched well (Each battery voltage ≦0.05V, IR≦15 mΩ, capacity≦30mAh) to make sure the better consistency of the battery.

• The cell must be connected in parallel first after then connected in series.

Connection: 

• Connect charging /discharging wire, battery-pack negative wire.

• After confirming the wires are connected OK, plug the connector cable in the BMS

• Do not plug connector cable in the BMS before connecting wire.

• Attention, ESD protection during work.
