The Comvolt 4000 Expansion Battery adds 320Ah of 12V LiFePO4 capacity to a Comvolt power station. It connects with the supplied Anderson cable, and an RS-485 link keeps the station and the pack in sync.
It has two 120A Anderson ports for charging and discharging, a power switch and reset button, and self-heating cells for charging in the cold. There is no inverter or outlet on the pack itself: it is extra storage for the station it is plugged into.
