Estimate the additional runtime this expansion battery could provide when connected to a compatible power station.
Estimates vary with device power use, cycling, and conditions. Check voltage, continuous output, and starting-power compatibility.
Device presets are examples: refrigerator 75W average, router alone 15W, CPAP 40W, TV 100W, and sump pump 600W while running. CPAP heating and additional network equipment can increase usage. For a custom cycling device, enter average watts over time.
Battery estimates use an illustrative 85% usable-energy allowance and 10W system overhead. Actual usable energy depends on battery chemistry, load, discharge limits, temperature, and inverter efficiency. Pump coverage assumes the chosen cycling rate stays constant.
Total nominal battery capacity used: 3840Wh.
This is estimated added duration with a compatible main station. Check whether this storage module requires a compatible main unit; independent outputs vary by model.
Energy duration does not confirm that a station can run or start a device. Check voltage, continuous and surge ratings, individual outlet limits, and connection requirements. For multi-station kits, this estimate pools the included storage; available runtime for a particular outlet or split-phase load depends on the approved configuration and load balance.
Pecron EP3800-48V Expansion Battery
The Pecron EP3800-48V Expansion Battery adds a substantial 3840Wh of capacity to compatible Pecron power stations. This updated model replaces the older EP3000-48V (3072Wh version), offering more energy storage for extended off-grid use. It is designed for scalable expansion, pairs seamlessly with supported units via cascade ports, and is ideal for longer camping trips, fieldwork, RV adventures, and home backup during outages.
Delivered in 3-5 business days.
Why Is The EP3800-48V Popular
The EP3800-48V delivers increased large-capacity LiFePO₄ storage in a 48V system for stable, efficient power delivery. It provides more runtime without added outputs or inputs on the battery itself (expansion-only design), making it cost-effective at around $0.18/Wh in some listings. Pair it with compatible Pecron stations to scale capacity significantly for multi-day needs.
What Will The EP3800-48V Power Up?
It extends the runtime of your compatible Pecron station dramatically, keeping high-draw devices like refrigerators, power tools, laptops, cameras, networking equipment, lighting, and appliances running longer during trips, remote work, or power outages. For example, it can help scale systems to thousands of extra watt-hours depending on the main unit and number of expansions.

Covers battery and related components as per Pecron's manufacturer policy.
Most expansion batteries are designed to work with a compatible main power station and may not function as standalone power stations. Always check the product specifications before ordering.
It increases total battery capacity and helps extend runtime for outages, RV use, off-grid setups, and longer backup needs.
Expansion battery compatibility is model-specific. Always confirm the exact power station model and compatible battery before ordering. Some older power station and battery combinations may be discontinued or no longer available.
Expansion batteries are best for customers who already own or are buying a compatible power station and want longer runtime for home backup, RV power, or off-grid use.
Unless the listing expressly says otherwise, an expansion-battery listing does not include the main power station. Confirm whether the required expansion cable is included with the battery or must be purchased separately.
Estimated total delivery is 3–5 business days, including handling and transit, subject to product availability. Business days are Monday–Friday, excluding holidays. Product-page preorder or backorder dates override the standard estimate. Review the shipping and availability information above and our Shipping Policy.
