Industrial-Grade Performance & Durability

The Storagedock ES5.4K (51.2V / 106Ah) is built to the highest standards of lithium technology. By utilizing bolted Grade A LiFePO4 Prismatic cells with a 5000N clamped force and MICA-based dividers, this battery offers exceptional structural integrity and thermal stability. Designed for longevity, it provides 4.32kWh of usable energy at 80% Depth of Discharge and is rated for 4,000 cycles.

Smart Monitoring & System Intelligence

This battery features a comprehensive user interface, including an integrated 3-page color touch screen for real-time data. For remote management, the ES5.4K includes a Bluetooth App for both Android and iOS, alongside CAN-bus communication specifically optimized for Victron Energy ecosystems. The system records all historic parameters and features integrated SOC (State of Charge) and SOH (State of Health) communications for precise energy management.

Advanced Safety & Scalability

Safety is paramount, with a built-in 100A BMS and a 125A circuit breaker with trip function. To maintain optimal cell health, an integrated 3A active cell balancer works continuously to prevent voltage drift. For larger energy requirements, the system is highly scalable, allowing up to 8 units to be connected in parallel to create a massive 43.2kWh energy bank. The unit is housed in a durable galvanized steel cell pack with a polymer-coated steel shell, suitable for wall or floor mounting.
