Note: 6,000 cycles achievable if the battery is not discharged below 50% DOD; 3,500 cycles at 70% DoD. All data based on UFOPOWER standard test procedures; actual performance may vary according to local conditions. Only authorized personnel should operate or adjust the batteries. Customizable battery bank and OEM solutions available for different RV types.
Engineered to the standards of the automotive industry, the series resists vibration and shock on any terrain while delivering over 6,000 cycles at 50% DOD (3,500 cycles at 70% DoD) for long-term reliability.
Automotive-grade LiFePO4 cells engineered to resist vibration & shock
>6,000 cycles at 50% DoD; 3,500 cycles at 70% DoD
10-year service life design
Remaining capacity at end of life: 70% (EOL)
Natural (passive) cooling – silent, no moving parts, zero maintenance
Built-in aerosol fire extinguisher protects against thermal runaway, while battery heating and anti-vibration design let you ignore terrain and temperature – with IP65 protection that even allows outdoor installation.
Built-in aerosol fire extinguisher – protects against thermal runaway
Battery heating function for charging and operation in cold climates
IP65 dust & water protection – can be installed outside RVs for longer lifespan
