Hi. Now the better weather is approaching im itching to get out for long weekends on the ebike and i'm looking for a cheap, basic set up for charging my bike up in my berlingo, either when parked up, or on the road. Not sure whether 2x car battery is the way to go, or leisure battery/inverter set up? I don't touch electrics so i'm pretty clueless as what would be needed solely to charge my bike. My mates son is a motor electrician, so he will do the fitting. Thanks.
