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
