I'm thinking of making a battery charger for my e-bike that can use my car's battery. The end-charge voltage of the e-bike battery is 42v, so you need a step-up that brings the 12 volts of the car battery to 42v with a current of 2-3 like that of the battery charger of the original e-bike.
I often run out of battery midday and not having the ability to recharge the battery with a 220V outlet is frustrating.
