Peak Power Pack is a complete replacement for heavy lead-acid batteries in places where high current values occur for short periods of time. It is primarily intended for caravan movers and is equipped with a built-in charger, which makes it possible to charge from the car's electrical system during transport of the caravan. The battery unit will thus be charged on arrival at the campsite. The charging can optionally also be done using the supplied adapter for a mains socket. It is also possible to charge from a solar panel.
