Rich Solar 12V 20A DC to DC Battery Charger
Features
Broad System Compatibility
- Compatible with 12V AGM, Flooded, Gel, and Lithium batteries
- Compatible with smart or traditional alternators via connection to the 12V starter battery
- Ideal for RVs, vans, boats, and off-grid power systems
Smart Multi-Stage Charging
- 2-stage charging for lithium batteries
- 3-stage charging for lead-acid batteries (Bulk → Absorption → Float)
- Lithium Battery Activation: Automatically wakes up over-discharged lithium batteries
Smart Protection & Control
- Built-in protection against over-voltage, over-temperature, and reverse polarity
- Battery isolation prevents reverse current between batteries and protects the starter battery
Advanced Control Interfaces
- D+ Ignition Terminal: Charges only when the engine is running to protect the starter battery
- LC Terminal: Activates low current mode (10A) for small alternators or weak power sources
- RJ11 Temperature Sensor Port: Adjusts voltage for cold and hot environments to protect battery lifespan (Not for lithium batteries)
*D+, LC cables, and a temperature sensor are not included
