Product Description
EMB20S002C | Parallel BMS PCB for Lithium Batteries
60A Current Handling | Balanced Charging & Discharging | Compact 120×93mm
The EMB20S002C Battery Management System (BMS) is a specialized PCB designed for connecting lithium batteries in parallel configurations. It addresses the critical challenges of parallel battery operation — ensuring balanced charging and discharging, equal current sharing, and comprehensive protection across multiple battery modules. With a maximum current handling capacity of 60A and a compact 120×93mm form factor, this BMS is ideal for scalable energy storage systems, backup power banks, electric vehicle battery expansions, and industrial battery racks.
📡 General Info – Why Use a Parallel BMS?
Connecting lithium batteries in parallel increases capacity and runtime but introduces risks such as circulating currents, uneven charge/discharge, and potential overloading. The EMB20S002C BMS solves these issues by actively managing each parallel branch, ensuring that current is distributed evenly and that all modules operate within safe limits. It monitors voltage, current, and temperature in real time, and provides overcharge, over-discharge, over-current, and short circuit protections, significantly enhancing safety and extending the lifespan of your parallel battery system.
