That's suprises me is that the GP3300SP2 has almost the same mah as IB3600 and more than the GP3700 and Sanyo 3600!!!

Also, best lap doesn't mean anything since it might the last pack JM tested so he got the hangd of the track better!

It could be done for marketing purposes since Team Orion is about to lunch the GP3700!

Yes, that's about it.
If we were to have someone from SMC+a publishing entity do a similar test, probably the Intellect cell would come out 'faster'.

If Orion finds the IB3600 better than GP3700, I am sure they would sell them........
They race what they sell so I assume they still want to win races and only use the best material available at all times!!

This is from the Orion forum a few days ago:

The fact that it can be confirmed that the IB cell outperforms the GP3300 and this is not reflected in the results makes the test suspect. I would venture a guess that the results were wishful thinking, especially when you have a strong committment (read purchase orders) to GP for the 3700. I guess we will find out. You all may want to save these results for future reference.

As I have stated on the SMC IB3600 thread we are buying and selling the latest improved IB3600 cell. Josh Cyrul and Jim Dieter who have been doing our track testing have commented that the IB3600 cell is faster on the track.

SMC has always used and sold what we feel is the best race cell. The track performance we have seen with IB cells has convinced us that this is the way to go.

This test is OK but I leaves too many variables up in the air. As nice as a track test it, too many thing can be atributed to some other thing (driver, motor, tires, setup, etc...).

To truly get an accurate resluts you would need to setup a test that removes variables like the driver and the car but still keeps and accurate "on track" performance. If I had the time (and money) I would setup a test like this:

1. Get battery packs, all new from one matcher, SMC or Orion, or whomever. 3 packs of one type, 1 packs low numbers (pic one stat to go off of, say voltage), 1 mid-range, 1 high numbers.
2. Charge them up at the same rate (say 6A, with 25mV peak)
3. Using a setup that could dischage the packs at a variable rate (100% for 3s (down the straight), 75% for 2s (throught the sweeper), 50% for 2s (hair pin), 50% for 5s (Chicane) , 100% for 2s (sweeper), 50% for 3s (on-to straight), then repeat). Do this discharge procedure 10min after full change.
4. Record the results and plot using excel (do three or Four cycles) and compare

If I was back in school this would be an excellent engineering undergrad project. Using a motorola micro controller this could be done. But I'm a woking stiff now, no time for this.
