Seplos 48V 100A LiFePO4 BMS

Sold out

The Seplos 48V 100A LiFePO4 BMS provides a robust battery management tool designed for 16s cell battery packs.

Seplos BMS contain a vast range of protective features to ensure your LiFePO4 battery pack operates within safe operating limits, recognises fault conditions, and takes appropriate action to prevent damage to the battery and any connected equipment.

Utilising CANBUS and RS485 communication 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. A full user manual can be downloaded here.

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