Votronic charge booster / charge controller for Mercedes-Benz Marco Polo, Horizon, Activity W447, perfect charging while driving for your campervan

The Mercedes-Benz Marco Polo has a regulated alternator, which ensures that the vehicle's batteries are charged poorly or not at all while driving. By installing the charge booster / charge controller, we prevent the alternator from switching off and ensure that the starter battery and the body battery of the Mercedes-Benz Marco Polo are charged with up to 30A.

The charge booster is mounted under the driver's seat of the Mercedes-Benz Marco Polo and is not visible. The original battery cut-off relay is therefore superfluous.

Why install a charge regulator?

• Optimised charging characteristics for acid, gel, AGM and LiFePO4 batteries (AGM is originally installed in the Marco Polo, we mainly install LiFePO4 batteries)
• High performance for short journeys
• Significantly improved energy balance of the on-board battery / body battery of the Mercedes-Benz Marco Polo
• Particularly recommended for vehicles with Euro 6 standard as alternators are regulated / switched off
• Temperature sensor that prevents the LiFePO4 batteries (if installed) from being charged at excessively low temperatures

Recommendation

We recommend installing our lithium battery for the Mercedes-Benz Marco Polo only with the charging booster. If you really want to be self-sufficient when travelling, we recommend our smart solar system for the Mercedes-Benz Marco Polo W447.
