Our take on the PECRON EP3800-48V Expansion Battery 3840Wh

The PECRON EP3800-48V is a 3,840Wh LiFePO4 expansion battery for PECRON's 48V power stations, including the E3800LFP, E3600LFP, F5000, F3000LFP, E2400LFP, E1500LFP and E1000LFP. It adds roughly 3.8kWh of storage to a compatible unit, with a built-in BMS guarding against overload, over-current, short circuits and overheating. LiFePO4 chemistry is rated for about 3,500 cycles to 80% capacity, which is longer-lived than the NMC packs on many rival expansions. At about 66.8 lb it is a stationary add-on rather than something you carry, and it only works with PECRON's 48V ecosystem, so it is not a fit for other brands.

Questions and answers

Which PECRON power stations does the EP3800-48V work with?
It is listed for the E3800LFP, E3600LFP, F5000, F3000LFP, E2400LFP, E1500LFP and E1000LFP. It is a 48V expansion pack, so it is not meant for other brands or non-48V units.
How much runtime does it add?
It adds 3,840Wh, or about 3.8kWh, to the host station's own capacity. Actual runtime depends on the load and on the host unit's inverter.
How long will the battery last?
PECRON rates the LiFePO4 cells at about 3,500 cycles to 80% capacity. That is a longer service life than typical NMC expansion packs.
Can I charge or store it in freezing weather?
No. Charging and storage are both rated for 32–113°F (0–45°C), so keep it above freezing.
Does it have its own outlets or inverter?
No. It is a battery only and needs a compatible PECRON station to deliver power. The built-in BMS handles protection, not output.
How heavy is it, and can I move it alone?
It weighs about 66.8 lb (30.3 kg), so plan a fixed spot and a second person for lifting.
Where is the PECRON EP3800-48V Expansion Battery 3840Wh cheapest?
