Default Re: Battery Charger/Maintainer suggestions

Gerry,

That's risky if one battery is bad will ruin good one.

I did multi battery. You needed a high amp diode ( about $10 or less) put in to block a reverse current flow from battery to battery. Current goes in RED side, but not back out.

Can you tell I was an electrical engineer in prior lives?

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??
