Have not got any pics of my PS, batterys dead in camera.
To use the car better is pretty simple. Find somthing like a large crocodile clip to go on both terminals of the battery and then clip all your equipment to it.
Some equipment comes with connectors like corrally ones, you can buy small clips to attach to these to make it easier.
You will need a 12v car battery charger. I assume you wil be able to buy these from that shop that you all seem to buy everything from.... "Walmart" I dont know as im in the UK :P Charge time varies on type of battery and charger.
Pretty straight forward.
