Electrical help for some crazy idea I got

[jo3]

you could always set up a leisure battery in your boot with a one way circuit, so you can full power from that and if it dies you can still start the car and you can just keep the car running for a bit if ur leisure batter dies and it wil still power it, and then your alternator will keep the both batterys charged all the time, you just might wanna think about upgrading the alternator tho depending on what your powering. but a couple of lights you prob wont need to.
