Product Description

Feature

DC-DC charger that can charge the main battery through the alternator and starter battery, or solar panels to charge the main battery (some models). Designed specifically for motorhomes, campers, ships, etc.

B2B Charge

Charge the main battery through the alternator and starter battery. If not used in a vehicle, you can also use one battery to charge another.

When running, the vehicle alternator quickly charges the main battery at full power.
Automatically boosts or steps down to ensure compliance with the standard battery charging curve.

MPPT Solar Charge

Harness maximum power from your solar panels to efficiently charge your batteries.

Increases solar panel charging efficiency by 10-30% via MPP technology.
Charges according to standard curves by boosting or stepping down voltage dynamically.
Provides a trickle charge to the starter battery when the vehicle is parked long-term.

Frequently Asked Questions

What is a B2B charge?

B2B (Battery-to-Battery) charging utilizes the vehicle's alternator and starter battery to charge the main service battery while the engine is running. It can also be configured to charge one independent battery using another.

How does MPPT solar technology improve efficiency?

The built-in Maximum Power Point Tracking (MPPT) technology dynamically checks and adjusts the voltage output of solar panels, increasing charging efficiency by 10% to 30% compared to traditional controllers.

Which battery types are compatible with the B2B1260 charger?

The charger supports standard Gel, Sealed, Flooded, LiFePO4, and Lithium-ion batteries as the main service battery, and Lead-acid batteries for the vehicle's starter battery.

Does this charger prevent the starter battery from draining?

Yes. When the vehicle is idle for an extended period, the charger maintains a small trickle charge to the starter battery, ensuring it has adequate power to start the vehicle.

How does the charger maintain correct charging voltages?

The charger automatically boosts or steps down the incoming alternator or solar voltage to deliver stable current and voltage suited to the main battery's specific charging curve.

What optional accessories can I connect to this unit?

Optional accessories include the MT-2 system monitor, a BT10 Bluetooth-Dongle for wireless data reading, and a TRS Temperature Sensor for temperature-compensated charging.
