Flagship Capacity & Industrial Build

The Storagedock ES12K (51.2V / 234Ah) is engineered for users who require the maximum possible energy density in a single footprint. Constructed with bolted Grade A LiFePO4 Prismatic cells clamped at 5000N and protected by MICA-based dividers, it ensures industry-leading structural integrity and thermal management. With 9.6kWh of usable energy at 80% Depth of Discharge and a 4,000-cycle rating, it is designed to power heavy-duty industrial and commercial loads with absolute reliability.

Advanced Monitoring & System Intelligence

Monitoring this high-capacity unit is made simple through a comprehensive digital suite. The ES12K features an integrated 3-page color touch screen for direct on-site data access, complemented by a Bluetooth App for mobile monitoring on Android and iOS. For seamless system integration, it includes CAN-bus communication fully compatible with Victron Energy ecosystems, providing high-resolution SOC (State of Charge) and SOH (State of Health) data while recording all historic battery parameters.

Elite Protection & Scalability

Safety is managed by a high-output 200A BMS and an integrated 200A circuit breaker with trip function. To maintain the health of the massive cell pack, a 3A active cell balancer works continuously to ensure voltage equilibrium. For large-scale infrastructure projects, up to 8 units can be connected in parallel, creating an expansive 96kWh energy storage bank. The unit is housed in a rugged polymer-coated steel shell with a galvanized steel internal cell pack, designed for professional wall or floor installation.
