About This

• 3840Wh Energy and 2560W Load Power: Expand via 4P4S up to 40.96kW / 61.44kWh - flexible scaling to match off-grid homes, RV systems, and solar banks.
• EV-Grade Cells & ETL Certified 200A BMS: with Grade-A LiFePO4 Cells and smart BMS protect against overcharge, over-discharge, over-current, overheat and short circuit - safer, steadier power for RV, marine, solar and backup loads.
• 10+ Year Design with 4000 Cycles at 100% DOD: Far longer than lead-acid. Fewer replacements and more dependable long-term energy for full-time RV and off-grid use.
• Cost-Efficient Energy: Up to 15,360 kWh total output (3840Wh × 4000 cycles). Clean, stable power that can cut energy costs vs grid use and reduce long-term expenses.
• High Energy Density: Only about 1/3 the weight of same-capacity lead-acid and 61.14Wh/lb - easier to carry, saves space, and delivers strong power in compact installs.
