Parallel box question

[gscott1979]

I took my batteries out of the box that I've just built to give them a charge and found one was at 3.69v the other was still at 4.19v, the first time I recharged them they had run down even to 3.8 before I charged them up now this has happened any help would be appreciated
Cheers

Surely one of the cells was not making a connection so all the power was coming from the other cell.

Alright mate,that was one of the first things I checked and all the solder joints are solid and the batteries are a snug fit in the sled,but cheers I'll have another check[emoji106][emoji3]

what about trying single battery in each slot in turn and see if it will fire coil?

Just tried that it seems to be firing will just have to see if the batteries drain equally this time if not I'll just gut the box and redo it when my new solder gets delivered
