Problems Solved
✅ Satisfy fast-charging demand for large-capacity RV auxiliary batteries. 40A high output. Charge batteries via alternator while driving and solar power when parked, dual power sources ensure stable off-grid power for camping.
✅ 4-stage intelligent charging system with selectable battery profiles, including 4 dedicated lithium battery modes. It follows optimized charging curves to protect cells and extend battery service life.
✅ Low 2.0V startup voltage, works for 60–600Ah large batteries, ideal for long-time off-grid camping.
✅ Starter battery protection: automatically cut off charging when alternator or starter battery voltage falls below 12.5V, preventing starter battery drain and no-start risk.
✅ Built-in solar charging function. No separate solar controller required, reduces parts count, simplifies wiring and lowers RV conversion expenses.
✅ Wide battery compatibility: AGM, Gel, Lead Acid, Calcium and LiFePO4, fits diverse RV power system builds.
✅ Lightweight design at only 1.2kg with compact size and pre-wired cables, easy to wire and mount inside limited RV compartments.
