Features

• Synchronous rectification technology
• Internal resistance capacitor filter, withstands high temperature
• Organic silicone packaging technology
• Chip smart protection: anti-overheating and overcurrent protection
• Anti-shock, anti-drop, anti-moisture, anti-dust
• High efficiency: 95%
• Non-isolated between input and output
• Waterproof enclosure: IP68

B2B Charge (Battery-to-Battery)

• Charges the main battery through the vehicle alternator and starter battery
• Can be used outside vehicle to let one battery charge another
• When vehicle runs, alternator can charge the main battery at full power through the charger
• Charger boosts or steps down to apply specified voltage/current and follow a standard charging curve

MPPT Solar Charge (if applicable)

• Improves solar panel charging efficiency by 10–30% via maximum power point tracking (MPPT)
• Boosts or steps down to provide the specified charging current and follow the battery charge curve
• Provides a small trickle charge to the starter battery when vehicle is unused for long periods to ensure start capability
