DC- DC charger that can charge the main battery through the alternator, and starter battery, or Solar panels charge the main battery (some models), DC- DC battery charger designed specifically for motorhomes, campers, ships, etc.
B2B Charge
It means to charge the main battery through alternator and starter battery. If it is not used in the vehicle, you can also use one battery to charge another battery
1. When the vehicle is running, the vehicle alternator can quickly charge the main battery through charger at full power
2 .The charger can charge the main battery according to the specified voltage and current by boosting or stepping down to ensure that the main battery is in accordance with the standard charging curve charging
MPPT Solar Charge
1.The charger can increase the charging efficiency of the solar panel by 10-30% through MPP technology (search for the maximum power point)
2 . The charger can charge the main battery according to the specified current by boosting or stepping down to ensure that the main battery is charged according to the standard charge curve charging
3 . When the vehicle is not used for a long time, you can maintain a small trickle charge flow for the starter battery to ensure that the starter battery has enough electricity to start the vehicle

B2B FAQ
Do you support BMS communication on your chargers?
Yes. Where the model supports it, the charger can communicate with the battery BMS over CAN or RS485 so charging stops at the values your BMS expects. The interface fitted to this model is listed in Key Specifications.
Can the charging curve be adjusted to our battery?
Yes. Charging voltage, current and the CC/CV stages can be set to your pack specification as part of an OEM / ODM order. Send your battery datasheet and we confirm the profile.
Can you supply the connector we already use?
Yes. We can fit your existing connector type and pin-out, or supply a matched connector and cable assembly.
Do you offer Custom Branding?
Yes. Custom Branding is available on the product label, housing and packaging for OEM and ODM programs.
How does sample development work?
Send your specification and target quantity. We confirm the configuration, provide a sample lead time and quote, then move to production once the sample is approved.
