Mercedes Vito W447 and Marco Polo leisure battery: how much capacity?

In a medium van, match energy carefully: a huge battery takes space and adds weight; one too small restricts fridge, lighting and electronics.

Campervan beside the ocean at sunset, illustrating on-board power needs — In a Vito, every litre of storage counts; electrics should be compact and sized to actual consumption.

Calculate in Wh. Ah only makes sense with voltage. Combine daily use, autonomy days and charging method.

What determines capacity

Refrigerator

Usually one of the main continuous loads.

Electronics

Phones, laptop, lights and pumps add up.

Charging while driving

Daily driving reduces stationary reserve needs.

Portable solar

Modular power without loading the roof.

Start with the consumption calculator then use the battery calculator.

Frequently asked questions

Is more capacity always worthwhile?

No. It adds cost, weight and volume and must also be rechargeable.

Fixed or portable solar?

Depends on use and roof. Portable solar may make good sense for a Vito.

Power planning · Mercedes Vito / Marco Polo

Follow the system, not a single part.

Start with consumption, then check runtime and weight to coordinate battery and solar.

1 · Calculate consumptionActual Wh/day before choosing capacity. 2 · Calculate battery capacityIndicative capacity by days of autonomy. 3 · Size the solar systemCalculate daily energy recovery. 4 · Check weightBattery, water and equipment also use payload.
