Seplos 48V 200A LiFePO4 BMS (V3.0)


The V3.0 Seplos 48V 200A LiFePO4 BMS provides a robust battery management tool designed for 16S cell battery packs.

This BMS contain a vast range of protective features to ensure the battery pack operates within safe operating limits, recognises fault conditions, and takes appropriate action to prevent damage to the battery and connected equipment.

Utilising CANBUS and RS485 inputs, heating function, Bluetooth, screen and communication port. It can be programmed to communicate with inverters, chargers or loads, to optimise its performance and protect the battery pack from overcharging, over-discharging, short circuits, and overheating.

Please note; this is the Type B Seplos V3.0 LiFePO4 BMS.

Seplos 2A Active Balancer
The V3.0 Seplos BMS also comes with optional Active Balancer. Seplos Active Balancer Board. This can only be used with the compatible Seplos BMS V3.0 - it will not work with previous versions.

The board gets energy from the battery pack, and 3 circuits can be activated at the same time. Each circuit offers a 2A balance current.
