12V to 14.6V DC-DC Battery Charger, 10A to 50A
A step-up battery-to-battery charger that takes 12V vehicle power and delivers a regulated 14.6V charging profile. It is built for motorhomes, campervans, boats and service vehicles that need their auxiliary battery charged properly from the alternator, or from a solar panel on MPPT models.
Why Choose This Charger
- Charges the house battery from the alternator. While the engine runs, the charger draws full power from the alternator and boosts it to the correct charging voltage.
- Follows the battery charging curve. Output is regulated by boost or buck so the auxiliary pack is filled on the standard multi-stage profile instead of an uncontrolled voltage.
- MPPT solar input on MPPT models. Maximum power point tracking lifts solar harvest by roughly 10 to 30 percent, and a small trickle output keeps the starter battery topped up when the vehicle stands for long periods.
- Sealed against water and dust. IP68 housing with organic silicone encapsulation and internal-resistance capacitor filtering for high-temperature operation.
- Protected on every side. Chip-level protection covers over-heating, over-current, reverse battery connection, no-load and short circuit.

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.
