Default Newb battery question? (go easy on me)

I bought a couple of used batteries, the kind somebody assembled themselves side by side like this [][][][][][]. The positive end of the first battery is connected to the negative end of the last battery with a single wire. Why? What does that do?

Thanks.

If you can please post a picture of the pack to help others diagnose the problem.

From what your post says it sounds like the past user was "dead shorting" the pack.

Good luck,
Shaggy

They are deffinitely dead shorted. I wonder how long they have been like that and if they will come back. I personally never did that so I can't say for sure how they will be once you remove that wire and put a charge in them.

Deadshorted packs are said to have higher voltage but at the expense of runtime.

So usually those who race stock class might do this. The previous owner probably ran stock class.

I run stock and have never done this myself. I understood it to be a marginal benefit at best. Plus the packs I have now are really not supposed to be deadshorted from what I was told. Too much money spent to risk ruining a pack like that imo.

The pack on the right in the picture has a better chance of life being a GP pack (33 or 37), as they work when dead shorted, where the IB's store better with voltage in them.

Do you know how long the packs have been stored like that?

Yes...From what I know so far. IBs do not like to be deadshorted. You can do it to the good'ol 3300s or 3700 GPs.

Current IB cells like to 4200s will die soon after....

GP cells work great after being stored deadshorted. In fact dead shorting was a virtual necessity with those cells to be fast in stock.

But unfortunately for our friend here, the cells he bought from the guy are IBs.

He has got one 37 GP and one 38 IB so he has a mix.

Yep one is 3700 GP, I got them from a HS/Indoor carpet track so I don't think they sat for too long. They must be no good for racing anymore since he was getting rid of them but he said they should be good for what I am doing with them (backyard dirt track bashing).

I will be testing them out later today to find out if they are any good.

Thanks for the responses.

I was tought when taking the wire off after shorting let them sit for alittle bit before charging. I used to let mine sit 30 min.
