The VBCS 12V Triple Charger from leisure electronics specialists Votronic is the ultimate all-in-one leisure battery charging solution for your campervan or motorhome.  This compact unit can manage multiple charging sources thanks to its combination of a 30A battery-to-battery (DC-DC) charger, a 20A mains-powered charger and a 250W MPPT solar controller, enabling you to charge from your vehicle's alternator whilst on the move, from an AC mains hook-up whilst on site, or from solar panels whilst wild camping. A remarkable feature of this three-way charger is that Votronic has managed to build all of this functionality into a unit that is not much larger than a standalone mains charger, saving space, cabling and installation time when compared with fitting three separate pieces of equipment.

The VBCS has a huge number of features and options (see list below) to optimise the charging of your 12 volt battery from multiple sources and can be fitted to vehicles with either standard or Euro 6 'smart' alternators. The selectable charging profiles mean it can be used with any lead-acid battery, as well as lithium LiFePO4  batteries and they are fully protected against both over-charging and unwanted discharging.

Important - only to be used with solar panels that have an Open-Circuit Voltage (VOC) of 36V or less.  Greater voltages may damage the unit and will void the warranty.

Suitable for 12V nominal voltage systems (not compatible with 24V or higher).

Excellent triple charger
28 October 2020  | 

I purchased the charger to replace an Electrobloc EBL99K in my Hymer. The Electrobloc was starting to boil my battery when charging on mains. Luckly I had fitted a current meter with a temperature sensor which alerted me to the issue. I feel much happier with the new charger having a temperature sensor included. The new charger is also compatible with AGM batteries. This was not possible with the EBL99K. Really please.
