Added the BSL 7kWh 51.2V 135Ah CANBUS LiFePO4 Battery to expand our backup capacity and the difference is night and day. We now get through extended Stage 6 outages with power to spare. The battery management system keeps everything safe and the unit runs cool. Excellent product.

The BSL 7kWh 51.2V 135Ah CANBUS LiFePO4 Battery is very well built and arrived well packaged from PowerVault. Installation was simple with the clear wiring diagram. We now have enough storage to run through the night on solar alone during summer. Battery has been rock solid.
