Seplos 48V 200A LiFePO4 BMS


The 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, the Seplos BMS 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.

This version of the BMS comes with Bluetooth functionality, and the display screen.
