Hmmm now that's using your nogin Frank. With a charger of this size I would think you could also charge 2 batteries at once by wiring them together, positive to positive and negative to negative. Hook the charger up to one and they both charge??

The way I understand it, in this configuration both batteries are going to level out to a common state of charge. In other words if one is 100% of charge and you connect it to another at 50% of charge, the 50% one will draw the 100% one down to 75% and both batteries will be charged at 75%.

I think what you'd want to do first is make sure each battery is fully charged independantly. Once you do that hook them up together and charge.

Does this make sense??
