Description

2S 20A Balanced BMS Battery Management Protection Board is designed for two 18650 Li-ion batteries connected in series. It provides essential battery protection against overcharging, over-discharging, and short circuits while also helping maintain a balanced voltage between the two cells during charging.

The module supports a battery voltage range of 7.4V to 8.4V and features dedicated B+, B-, BM, P+ and P- terminals for convenient connection. Its compact size makes it suitable for DIY battery packs, portable electronics, LED projects, DIY power banks and other battery-powered applications.

This BMS supports up to 13A maximum operating current and has a 20A maximum limiting current. Please note that this is a BMS protection and balancing board, not a standalone battery charger. An appropriate 8.4V charging source should be used.
