FOSSiBOT FB3840 3840Wh LiFePO4 auxiliary battery for F3600 Pro

The FOSSiBOT FB3840 is a 3840 Wh expansion battery designed to work with the FOSSiBOT F3600 Pro power station. Its built-in LiFePO4 cells are rated for more than 6500 charge cycles down to 50% of initial capacity, giving the system a long service life. Connecting two additional units expands the energy storage to 11,520 Wh.

The battery also works as a portable DC power source, with a 100 W USB-C port, an 18 W USB-A port and further 12 V outputs. This makes it suitable for travel, mobile work and keeping devices running during a power outage. A clear LCD screen shows the charge level and current operating values.

An integrated BMS monitors the battery and protects it against overheating, overload, overvoltage, short circuits and deep discharge. It can charge and discharge at the same time. At 42 kg it is heavy, but carry handles make it easier to move.
