⚡ Key Features

01Massive 3,840Wh Off-Grid Capacity

Delivers true multi-day power autonomy, allowing off-grid campervan users to run high-draw appliances without firing up a generator or searching for hookups.

02Direct Victron plugin via can ports - this unit can be connected into the Victron Cerbo GX without any need for an external shunt making it ideal as part of a high spec system with beautiful monitoring.

03300A Smart BMS with Active Balancing

Capable of sustaining 300A continuous current while actively equalising cell charges to maximize usable lifespan and prevent cell drift over thousands of cycles.

04Automatic Winter Pre-Heating

Built-in heating pads warm the cells to 5°C automatically before allowing charge current when ambient temperatures drop below freezing.

05Fogstar Drift App Connectivity

Live Bluetooth monitoring displays exact SOC percentage, individual cell voltages, temperature, and charge/discharge currents on your smartphone.

🔋 Estimated Runtime

Based on the System Builder’s appliance power and daily-use settings, with a 300Ah × 12.8V = 3840Wh lithium battery. Each tile shows one load on its own, with no solar or alternator charging; no reserve or losses are deducted. Real mixed-use runtime will be shorter.
