Problems Solved
✅ Meet fast charging needs for large-capacity RV auxiliary batteries. 40A high output. Charge via vehicle alternator while driving and solar panels when parked. Dual power sources deliver stable off-grid power for camping.
✅ 4-stage intelligent charging system with selectable battery profiles including 4 dedicated lithium battery modes. Optimized charging curves protect cells and extend battery service life.
✅ Low 2.0V startup voltage, compatible with 60–600Ah large-capacity batteries for long off-grid camping trips.
✅ Starter battery protection: automatically cuts off charging when alternator or starter battery voltage drops below 12.5V, preventing starter battery drain and no-start failure.
✅ Built-in solar charging controller. No extra solar regulator required, reducing parts, simplifying wiring and cutting RV conversion cost.
✅ Wide battery compatibility: AGM, Gel, Lead Acid, Calcium and LiFePO4, suitable for various RV energy storage builds.
✅ LED indicator panel for real-time charging status monitoring. Only 1.2kg, compact size for easy mounting in limited RV compartments.
