When the grid stays down into a second day, the real question is not whether your power station works. It is whether it still has charge left. One battery only carries you so far. The Pecron EP3800-48V adds another 3840Wh of stored power, so your backup keeps running long after a single-battery setup taps out.
The EP3800-48V is a plug-in expansion battery for Pecron's 48V LiFePO4 power stations. It is built for homeowners and off-grid users who need to ride out a multi-day outage, run a well pump or refrigerator overnight, or keep a remote cabin powered without hauling fuel.
Why add the EP3800-48V expansion battery
3840Wh of extra LiFePO4 capacity that stacks directly onto your existing 48V unit.
Built on LiFePO4 cells rated for 3500+ cycles to 80 percent, so it holds up to years of regular charging.
Works with the E1500LFP, E3600LFP, E1000LFP, E2400LFP, F3000LFP, and E3800LFP.
Add more than one battery when you need to scale capacity further.
Same battery chemistry as your power station, with no mixing of cell types.
What the EP3800-48V keeps running longer
Home backup: keep the refrigerator, Wi-Fi, and medical devices going through a multi-day outage instead of watching the charge drain overnight.
Off-grid and cabin power: bank more of your daytime solar so you still have power well after sunset.
Worksite and RV: stretch a full day of tools or appliances on one charge, then top back up from solar or shore power.
Can I connect more than one EP3800-48V? Yes. The 48V platform is designed to stack multiple expansion batteries, so you can keep adding capacity as your backup needs grow.
Is this the same battery type as my power station? Yes. The EP3800-48V uses LiFePO4 cells, the same chemistry as the host units, which keeps charging and discharging consistent across the system.
How is it different from the older EP3000-48V? The EP3800-48V raises capacity to 3840Wh, up from 3072Wh on the EP3000-48V, so each battery adds more runtime to your setup.
