Description

Li-ion 4S BMS Module – 14.8V – 40A

The 4S Li-Ion cell charging and protection module is a BMS 4S version 2.3 electronic circuit with a built-in balancer working as a battery protection against over-discharge, over-charging and also with a balancer and short-circuit protection function.

• Allows you to build a safe battery pack that does not need to be charged with special chargers for li-ion batteries.
• The 2-in-1 module was created to keep the cells in the best possible condition by not allowing them to overcharge as well as over-discharge. One module here replaces the charger and security module.
• In version 2.3, the anti-interference function has been improved, the heat dissipation has been reduced by 30% and the boot current has been increased. Balancer current is about 450mW.
