More runtime for a compatible PECRON platform

Add 3,840Wh without replacing the power station you already chose.

The PECRON EP3800-48V is a 51.2V, 75Ah LiFePO4 expansion battery designed to increase the stored energy of specific PECRON power stations. It is for customers who need longer outage, RV or off-grid coverage from a supported host system—not a standalone battery with its own appliance outlets or solar input.

The EP3800-48V must operate through a compatible PECRON host station and the correct PECRON connection hardware. It is not a general-purpose 48V battery, portable power station or independent solar battery.

Compatibility comes first

Buy it for the host station—not just the matching voltage

PECRON’s current U.S. product title lists the EP3800-48V for these host models:

E1000LFP
E1500LFP
E2400LFP
E3600LFP
E3800LFP
F3000LFP

Compatibility alone does not establish how many batteries a host accepts or which cable is required. Use the current manual for the exact host model and expansion configuration. PECRON specifically instructs F3000LFP owners to obtain the required XT120 cascade cable.

What the extra capacity changes

Longer runtime—not more inverter output

Cover longer outagesMore stored watt-hours can extend refrigeration, internet, lighting and other priority loads when utility power is unavailable.
Stay off-grid longerIncrease overnight and low-sun reserves for a compatible PECRON station in an RV, cabin or mobile setup.
Reduce deep daily cyclingA larger matched battery bank can spread a given energy demand across more capacity when used within PECRON’s approved configuration.
Important: Adding an EP3800-48V increases energy capacity, but it does not automatically increase the host station’s AC wattage, outlet voltage, solar-input limit or surge capability.

Plan the full system

Capacity math is simple; compatibility is not

Add 3,840Wh per supported batteryFor example, one EP3800 takes an E1500LFP from 1,536Wh to 5,376Wh. The host’s manual determines the maximum supported count.
Account for recharge timeA larger battery bank stores more energy, so a given charger or solar array will take longer to refill it from the same state of charge.
Plan the physical spaceEach battery measures about 17.3 × 12.2 × 8.8 in and weighs about 66.8 lb. Place it on a stable surface with room for cables and ventilation.

Long-service expansion

LiFePO4 chemistry rated for 3,500+ cycles

PECRON rates the EP3800-48V to retain at least 80% of original capacity after more than 3,500 cycles. The listed charging and storage range is 32°F to 113°F. PECRON lists a 1+1-year warranty under its current written warranty terms.

Common questions

EP3800-48V FAQ

Can I use this battery by itself?

No. PECRON describes the EP3800-48V as having no independent input or output. It must connect to a compatible PECRON host station through the approved expansion architecture.

Will it make my power station produce more watts?

No. It adds energy capacity and potential runtime. The host station still controls AC output wattage, voltage, surge behavior, ports and charging limits.

Is the EP3800-48V compatible with the F5000LFP?

Do not assume so. PECRON sells the dedicated FP5000-48V for the F5000LFP, and the current EP3800 product title does not list F5000LFP. Use the host manual or written confirmation from PECRON before ordering.

What cable does the F3000LFP need?

PECRON’s current EP3800 page instructs F3000LFP owners to obtain an XT120 cascade cable. Confirm the exact cable and current package contents before ordering.
