HI everyone, Ive been scoring the internet for a good charger thats easy on the wallet. And most of them seem to be around the same price range
and i've narrowed it down to ICE
I can afford the charger but not a power supply
so i wanted to ask could I use one of my old car batteries?
thanks for your help in advance

Sure as long as it's 12VDC. How do you plan on charging those?

We used Marine batteries for their deep cycling feature about twenty years ago.
