Optimized charging modules designed to bridge vehicle alternators and auxiliary batteries in modern caravans and boats.
Turkey has quickly become one of Europe's primary hubs for caravan, motorhome, and marine fabrication. Operating in key industrial zones like Sakarya, Bursa, Izmir, and Istanbul, Turkish coachbuilders and outfitters cater extensively to domestic demand and exports across the European Union.
With the rapid transition toward LiFePO4 (Lithium Iron Phosphate) house batteries, caravan electrical setups require highly specialized conversion systems. Modern Euro 5 and Euro 6 engines are equipped with smart alternators, which continuously drop their voltage based on ECU demands. This renders direct charging methods obsolete and necessitates the integration of high-performance DC-to-DC battery chargers.
Wemaxpower supplies high-grade DC-DC converters designed to ensure auxiliary batteries receive a stable, multi-stage charge curve, bypassing smart alternator fluctuations while preventing auxiliary currents from depleting vehicle starting batteries.
Engineered to deliver clean, isolated, and boosted power to auxiliary battery banks under harsh environmental conditions.
Modern vehicles with regenerative braking systems lower starter line voltages below charging levels. Our buck-boost technology maintains a consistent, programmed charge regardless of alternator output variations.
Sealed with thermal conductive epoxy resin, our waterproof chargers resist moisture, vibration, and dust ingress. Ideal for maritime vessels and off-road motorhome builds in coastal Turkish regions.
Delivers constant current and constant voltage (CC/CV) curves specifically matched to LiFePO4 cells, preventing cell degradation and overvoltage triggers on integrated BMS systems.
We offer ODM engineering services to fit customized chassis spaces, terminal connectors, and heat-dissipation plates.

Reliable, robust models catering to varying voltages, current requirements, and mechanical layouts.
With a 7-year track record in high-density power electronic design, Wemaxpower specializes in manufacturing high-efficiency programmable DC power supplies, DC-DC battery-to-battery converters, and industrial power modules.
Our production facilities utilize automated surface-mount technology (SMT) and automated optical inspection systems to guarantee solder point integrity. For international buyers in Turkey, we provide comprehensive technical documentation, including CAD drawings, step response metrics, and thermal parameters, ensuring seamless structural integration into caravan utility compartments.
Important steps to consider when selecting and deploying DC-DC battery chargers in professional RV configurations.
Traditional alternators provide continuous high output when the engine is running. Smart alternators reduce voltage (sometimes below 12.5V) to conserve fuel during acceleration. Our chargers feature a D+ terminal input linked directly to the vehicle ignition line. This signals the charger to run only when the engine operates, preventing deep starter bank depletion.
When pushing power from front-mounted start batteries to rear-mounted caravan storage arrays, long wiring runs introduce significant voltage drop. A standard buck regulator cannot output the necessary 14.6V if the input drops to 11.5V. Wemaxpower's buck-boost architecture steps up or down dynamically, maintaining proper CC/CV targets.
Unlike direct alternator linking which stresses battery plates and risks BMS overvoltage shutoffs, our units charge via three distinct phases:
