Default battery question for stock

I run 3300 gp packs in stock class. 1.16 - 1.15 v.
will i notice a big diff. running 1.18 to 1.20 packs. Can you feel the difference in punch/top end? I run a monster stock jr. and the car is dialed. If it is worth it i will spend some extra $$. please give me your recommendations
i need a little more thanks!

you will notice a difference with that volt gap. you need to look at the discharge rate to. most cells are now done at 35amp but some at 30amp. if you have packs with the same figures but different ampages the higher amped pack will perform better. there are other parameters to consider but its best to ask when you buy. doing stock you don't really need runtime so you could stick with 33's or IB36's.

maybe like .1-.3 a lap difference; but you can feel the power difference outta the corners

Perhaps I just got really lucky, but I have a pack of 3600 mAh Elite cells from www.cheapbatterypacks.com and it is amazing. On my ICE charger, it takes as much charge or more than my IB3800 packs and it consistently feels stronger than any other pack I own including some GP3300s rated at 1.18v @ 30 amp discharge and 2 different 3800 packs. Given that the Elite pack cost about $36 assembled with a Dean's connector, I think it is a screaming deal and worth another few orders. The only down side of the Elite cells is that I don't think they are ROAR approved, so if your track cares, its not a good choice.

i think that the rules for batts should be a capacity rule only & leave the brands or labels out of it.

being 3600mah i feel they should be allowed to run at sanctioned events, but i do not make the rules.

You didn't just get lucky, IMO. I also have a pack of those cells, got it as part of a Beta test they ran(they wanted to get some experienced guys to try them & report back on what we thought of their performance, & I was one of those guys, got a free pack from it) & I'm still using it today in club racing. I also now have some packs of IB3800's that are matched at 35 amps & have avg. per cell voltages in the 1.205 range, & honestly, it's hard to tell ANY difference between them & the Elite 3600's(they seem indistinguishable in my lap times & fel about the same ontrack). And I agree with you, I think they're about THE best bang per buck cells you can get right now, though you do have to be mindful of whether your local track will allow them(mine doesn't mind, I suspect only those places that are big on following ROAR rules closely all the time will have a problem with them). What I'd REALLY like to see is for some of the better battery matching companies get ahold of these cells & see what they can do with 'em(as far as I know, my cells were not conditioned in any way, no zapping or anything, so you have to wonder what the better matchers can achieve with them)....

I'm interested in these cells, what discharge procedure/storage do you use on them? do you dead-short them? I think these sound to be some good batteries... at least untill li-po rules the scene.

I don't know about what iblumberg does, but I've been treating my ack the same as my others basically, charging at 6.5 amps(though for the Elite3600's I've been using a 6mV per cell threshold instead of 5 that I use on the others), & after a run, discharge with my bulbs(built a 25 amp discharger with a 5.4 volt cutoff switch inline) & put on my Smart Tray set at .5 volts to finish, then put it away for the day(or if I need it again later that day, let it cool & then be ready to reuse). Then when I'm ready to use it again, tray it one more time at the same setting & charge it up, rinse & repeat, etc. Seems to work just fine, the pack hasn't changed a bit since I got it, stays strong & consistent(& I've had it for maybe 3-4 months or so).....

Im not sure how true it is but this is what i heard.. The IP3800 cell is actually a 3600 rated cell.. there made by a company called grepow i think is the spelling.. the ratings areactually less then what the cell is capable of.. I wonder if these elite cells are the same ones.. the dimensions listed are very close to the IP rated size.. there slightly larger then the IB's.. I know the IP's i have feel so much stronger on the track then my Ib's as well..

I think your right the first IP's may have been 3600's. But now they are definetly true 3800's. They have been revised. The latest cells have about 50 seconds more runtime than first batch.

If your setup is good, you'll definately notice a difference. Chassis setup means more than anything. Don't shy away from cell's done @ 30 amps either, just because a cell is matched @ 35 doesnt mean its automatically better than a 30 amp cell.

I have 30 amp cell's that are killer...just remember..setup, setup, setup.
