Default IB vs GP - Durability

I am sure this has been discussed somewhere already, but how do the GP and IB cells compare for durability? Is one more hardy than the other and what are the best ways to look after cells. I have a Novak smart tray and it mentions in the distructions that you shouldn't pulse charge Ni-mh cells, so is a 6 amp linear the best bet or maybe i should be using a linear step charge. I am using a robitronic overloader charger so i have plenty of options.

Above any other tips i a very interested to know about the durability of these cells before i go and buy some.

Cheers

I guess no one is qualified to answer your question until somebody have done extensive battery test eg. over 500 + cycling process to find out which brand produce higher voltage & capacity during its lifetime.

As far as longevity my IB's still have the same cycle numbers as they did in October. IR's raised like 3-4 points but I can live with that.
Runtime and voltage is the same.

People say you have to really take care of IB's.
How hard is it to tray it for a second, then charge, run it, then discharge and let sit ?

At least you dont have to fool with shorting them.

I hated to have to tray each pack until it hit 0.00 before it was safe to short it.

This is hard to answer because GP has now changed there cells and by doing so i'm sure they need to be treated differently than 3300s. I know that when we tested the original GP3700s they didn't hold up there runtime compared to the IB3800s.

Also while I was attending the DHI cup I saw allot of racers using GP cells putting new packs in the cars while we were using 3 packs of IB3600s for the 5 qualifiers on Saturday and 2 packs for the 3 A mains and Paul Lemieux ran his fastest run in the third main and that was with the same pack he used in the first main.

But Danny, if Paul wasn't driving with his mouth open in the first A-main he wasn't really hustling the car. When the boy drives with his mouth open though, man, he's on it! LOL

I never looked at him on the drivers stand I was to busy watching the cars on the track. All I know he did a great job driving a car that wasn't really easy to drive and in the last main his car was easier to drive and he was more competitive. It's very hard to get use a track, new car and rubber tires with one practice run.

Watch him sometime, it's true. If he's just kinda out there running, mouth closed. When he starts wheeling it, mouth's open. It's kinda like watching Jake Delhomme with his tongue during the Bears/Panthers game.

IB3800 packs are plenty durable......they just like you to pick and stay with a strict charge/discharge method.....follow the SMC instructions and you will never have an issue.

Our GP cells were really the same way.....the more strict of a routine you followed, the better they performed....

Later EddieO
