PECRON EP3800-48V Expansion Battery – 3840Wh LiFePO4 Battery

Seamless Expansion for Extended Power Storage

The PECRON EP3800-48V Expansion Battery is a high-capacity energy module designed to expand the energy storage of compatible PECRON systems that use an MJ32 cascade port. With 3840Wh (51.2V / 75Ah) LiFePO4 capacity and long cycle life, it is built for scalable runtime extension when you need more stored energy available in your setup

This expansion battery is engineered for cascade operation, using two MJ32 extra battery ports and a dedicated cascade cable connection to the host device.

EP3800-48V with 3840Wh Large Capacity can be used for E3800LFP E3600LFP/F5000LFP/F3000LFP/E2400LFP /E1500LFP/E1500LFP.

 

Key Features

Expandable Power & Compatibility

  • 3840Wh capacity (51.2V / 75Ah) for extended energy storage.

  • MJ32 x2 extra battery ports, designed to cascade with devices that feature an MJ32 cascade port.

  • Per-port cascade limit: each MJ32 port can be cascaded up to three units (exceeding this can increase resistance and voltage differences, which may prevent proper function).

Cascade Operation & System Behavior

  • After cascading, the pack can be used for charging or discharging, but the host will not display charging/discharging power separately. Current and voltage per pack can be viewed in the app.

  • Host connection is required: without connecting to the host, EP3800-48V units cannot be connected or activated.

  • For smoother balancing, PECRON recommends starting with battery levels within 10% between the host and the EP3800-48V.

Reliable LiFePO4 Battery Technology

  • Built with LiFePO4 (LFP) cell chemistry

  • Maintains over 80% capacity after 3,500 cycles (cycle-life spec)

  • Uses high quality UL certified automotive LiFePO4 battery (per the manual FAQ).

Operating Conditions & Practical Notes

  • Operating and charging temperature guidance in the manual lists 0°C to 45°C (32°F to 113°F).

  • Maximum operating altitude: 3000m

  • The product is not waterproof; prevent water ingress and maintain good ventilation at air inlet/outlet areas.
