If anyone has some of the original IB's in the 1.18 range, and some IB's in the 1.20+ range then you know how much quicker the extra .02 volts can be. To try and get some more performance from my 1.18 pack I changed my normal routine. I would'nt do this all the time but it really seemed to kick up the performance.
1. I charged at 7.0 amps on my Pitbull. (Normal 6.0 amps)
2. I raised the voltage cutoff.
3. I covered the pack with a towel to retain the heat generated during charging.
I raised the cutoff to get a higher peak temp in the pack. Normally I set the voltage cutoff to yield a 130 degree pack. This time the pack peaked at 140-145 degrees. The performance was equal to my 1.205 packs. My lap times are normally .2 sec slower with the 1.18's but they were equal to the 1.205's this time. It could have been my exceptional driving, LOL, nope just the batteries.
Now, all that being said, I know Danny would'nt advise the above technique. For me the 1.18's are just practice packs now so what the heck, right?
