i bought some batteries from a member and have a question about the setup.
they are set up individual cells and are + - + - + - and on the first and the last one there is a wire connecting the two?

when i have looked at others they have a red wire and a black wire for your connector. whay are these connected like this? seems like that would be shorting them out?

anyways, im sure there is some reason why, i just dont know it.

also, if so, do i un solder the wire making that connection and put on my own wires on pos and neg side?
thanks, Howard

this is how i thought it should be. but mine has the black wire going from end to end?

The cells are dead-shorted. Racers do this to increase the voltage of the pack.

so. that means it's not a 7.2v style anymore when that wire is like that? and what i need to do is undo that wire and solder on my own connecter liek the one pictured?

That pic is how they are supposed to be. A wire going from end to end is dead shorting the packs for storage. Not many do that anymore with nimhs. It makes it so you don't have to worry about them when you store them. The packs will run like crap for about 3 cycles or so when you first run them. Then they will "wake up" and be like normal. I wouldn't bother dead shorting them though, just store them half charged or so. Only really matters if they are not going to be used for a fairly long period of time.

It's still a 7.2 volt pack. Needn't worry about it increasing the voltage, or decreasing run time. Just don't do it anymore. Take the dead short wire off, and solder on your connectors and hit the dirt!!
