My PV charge controller cannot charge 6v batteries, so I'm planning to buy three 6v sealed lead acid to get the 18v to replace te battery of the drill wich got fried. I know I could connect two of them in series and charge them without problems, but wat about the third one?
Can I rotate one already charged and the third one discharged without damaging them? and recharge to fill the third one. I guess once connected in series voltage will level between the two to the average point. Is it recomendable to wait until that leveling ocurrs or it doesn't matther?
I don't know if my way of explaining what I want was clear.
Thanks and regards. Paul.
