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.

• 3840Wh expansion for even longer runtime requirements
• LiFePO₄ chemistry with 3,500+ cycles to 80% capacity for safety, durability, and longevity
• Cascadable design (via MJ32 ports) for stacking multiple units on supported models
• No independent charging or direct outputs—relies on the main power station
• UL-certified automotive-grade cells for reliability

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.
