I'm using a Pyramid PS12KX which is a 10A 13.8V supply. I can't remember where I got it but I think it was like $40, I'll try to find the vendor. To get the full 10A charge from the 106B+ in the higher voltage packs you'll need a more powerful supply though, I'd shoot for around 300W to be safe.
Ok, so something around the 300W range. Will start hunting around. Should be able to get one locally and not have to pay for the shipping. Just want to be able to charge at home before I take the truck out. When the batteries pooch I bring out the big dog (Baja)
Thanks guys.
