Pecron EP3800-48V Expansion Battery 3840Wh for E1500LFP, E3600LFP, E2400LFP & E3800LFP

Your power station runs out before the outage does. You sized it for a normal day, then the grid stays down for three, or the off-grid trip runs a week instead of a weekend. Buying a second station is expensive and bulky. There is a simpler fix.

The Pecron EP3800-48V is an expansion battery that bolts 3840Wh of extra LiFePO4 storage onto your power station. Plug it in and your runtime jumps, without a second inverter and without a second unit to manage.

How much longer will the EP3800-48V keep you running?

It adds 3840Wh, which is real time on real loads. That is roughly 22 more hours of a typical refrigerator on top of what your station already holds.

• Add about 22 hours of fridge runtime, or days of lights and devices, from a single expansion battery.
• Skip the second station. You reuse your existing inverter and ports, so you pay for storage, not a whole new unit.
• Stack for more. Add another expansion battery when you need to grow into multi-day or whole-home runtime.
• Set it and forget it. LiFePO4 cells cycle for years with no fuel and no maintenance.

Best for: owners of E1500LFP, E3600LFP, E2400LFP, E3800LFP who want longer outages covered or true off-grid runtime. Sizing a system? Our sizing calculator helps you plan.

More runtime, the simple way

3840Wh of LiFePO4 storage

How much does it add? 3840Wh of LiFePO4 capacity, the same trusted chemistry as your station, ready to cycle daily for years.

One cable, no extra inverter

It connects to your power station and shares its inverter and outlets, so there is nothing new to wire and nothing extra to carry power through.

Built to stack

Need even more? Add another expansion battery and grow your reserve toward multi-day or whole-home runtime, on your schedule.

Where the EP3800-48V earns its place

• Long outages: carry a refrigerator and essentials across multiple days instead of hours.
• Off-grid living: bank enough storage to run a cabin or RV through cloudy stretches.
• Worksite and events: keep tools and equipment powered through a full day and beyond.

Pair your system with a PV300 solar panel to refill the whole bank from the sun.

Why an expansion battery beats a second station

• Pay for storage, not another inverter and screen you already own.
• Manage one system instead of two separate units.
• Grow your runtime in steps as your needs change.
• Keep it all LiFePO4, with no fuel and no maintenance.

An expansion battery extends a power station by adding storage that shares the station's inverter and outputs. The EP3800-48V brings 3840Wh to that job, so a long outage or a long trip no longer outlasts your power.
