2.80 kWh 25.6V LiFePO4 (LFP) storageDOCK Battery (Rugged Camper)

Engineered for the Rugged Explorer

The ES2.8K is designed specifically for 4×4 canopy builds, off-road trailers, and motorhomes that require professional-grade power. Unlike standard lithium batteries, the “Rugged 4×4” model features bolted Grade A LiFePO4 Prismatic cells with a 5000N clamped force and MICA-based dividers. This specialized construction prevents cell movement and vibration damage, making it the most reliable energy partner for long-distance overlanding.

Intelligent Power & Seamless Integration

Equipped with a high-capacity 300A Internal BMS and an active 3A cell balancer, the ES2.8K maintains optimal cell health even under heavy loads. It is one of the few 25.6V batteries in its class to offer CAN-bus communication, providing a direct interface with Victron Energy ecosystems for precise monitoring via GX devices. The integrated automatic pre-charge circuit also ensures a smooth startup when connected to high-capacitance inverters.

High Discharge & Scalability

With a recommended discharge current of 70A and a peak discharge of 110A, a single module can comfortably power inverters up to 2kVA. For larger power requirements, up to 4 units can be connected in parallel, creating a massive 440Ah (11.2kWh) battery bank. Safety is reinforced by a built-in 300A ANL fuse, providing internal protection against extreme over-current events.
