The more you run a pack on the same track the faster it will get. I've showed up at Cleveland and gave out only one pack per driver. We now give a second pack in case something would happen to one of the packs.

At those big races where you race every 6-8 hours that is fine and in fact at club races if your pack cools down for one hour and half to 2 hours it can be used again and will perform as well.

If I treat my batteries the same then I know how to gauge them for my use. Everybody has their own way of gauging how long their batteries last by their own methods for their particular use. Since my use is in a 12th scale in the south Texas heat, that is how I go about telling if a battery is worthy of continuing to buying. Not only that, they sit in the back of my truck in my Ofna travel bag in a Racers Edge Battery case under a toneau cover another 2 hours or so till i get home. So, if a battery can withstand that type of treatment and still provide me the power I need after 6 or seven months then they are worth buying again if i can still get them. And that was money well spent on good batteries. Fyi, the back of my truck gets to about 120 degrees at times.

I'm glad that your packs have held up but my point is that cells from different manufacturers react differently. In your case if you use temp charging which seems to be what your saying then the IB cells should of been charged at 15-20 degress less to get them in the same state of charge as your IP cells. So basically your method is charging the IB cells more than the IP cells.

I don't temp charge as a main method of peaking batteries. I understand what you are saying that different manufacture batteries require different methods. However, I was just trying to say that if the EP batteries last as long as IPs in the same manner I use them than the IBs then it would be my preference to go with EPs.

Danny its good that IB is finally starting to get their act together regarding cell durability. I hope to see the IB cell continue to improve over the months to come. As we all know IBs exhibit excellent performance and only lack in the durability department...

However, I think your estimation of 8 packs per season is a little outrageous. Personally I think that if every racer were to buy that many packs per season, battery matching would be a dream job -- that's just not realistic in my opinion. I also don't think average racers want to spend $500-600 a season on cells. I could be wrong but I don't think so...

How do we test for a shorted cell in a pack of six (or four) ?
Do we send the whole pack back or just the bad one ?
Thanks.

Releasing the highest performance cell with pathetic life was a brilliant move.
