Hi,

i been out from electric racing for a year or so... used to run gp3700 batts, worked fine, now i'm trying to get some batteries, i can't find any gp4300 cells,
though ib has their 4200wc cells...

i would go with IB, but i'm not that kind of who will very properly tray every pack, then put it on charge for 10 mins etc, from reading forum i got the impression that IB's require lots of attention, though with GPs i never did nothing, and none batteries were dead, except unmatched 3300s which i been racing for 2 years

so, i wonder, what's the situation with gp 4300 or 4600 cells? anyone selling, matching them? couldn't find nowhere...

you can get unmatched 4300 cells from rcmart

They still have some GP4600 and GP4300 (what is it, SHV or something like that) at Orion.
Ordered some this week, hope I'll receive them today.

at orion? where is that exactly? teamorion.com?

does anyone know anything how does 4300 and 4600 perform?

All high capacity batteries are going to require attention, as the capacity goes up, the stability of the batts go down. Thats why we have $200 chargers and dischargers, the more you can moniter and manipulate what these batts are doing, the longer they are going to last. I haven't used the new GP4300 or 4600, from what I hear they have the same issues as the IB's. The reason you are having trouble finding matched 4300's is the first run of them had problems with stability, runtime, and punch, they were discontinued so GP could fix the problems with them.

yep, thats the company, my lhs phoned the company and they had stock of 4300shv and 4600. allthough they were not on the website they were available. pretty expensive though... but at least the power lasts longer than 3 months.


I know just as much as most, the 4300shv has a higher voltage and extremely low ir. 4600 has the runtime, my normal matcher told me the 4600 were better in quality so I went with these (delivery date of 4600s with him shifted to september and he's not happy abot it)

i guess i will get some 4600 unmatched , will be fine for some time at 36$/pack for local racing...

I built 2 side x side packs of These matched GP4300's from Integy and really like them. I ran some tests for top speed with GPS against some unmatched IB4200's and the GP's were +1mph faster average 2 pack vs 2 packs. I will be buying more...GP's are far more stable then IB4200's IMO.

why did you compare these matched GP packs against "some unmatched IB4200's" ???

Verndog

Because those were all I had the were reasonably fresh cells, and I know they were both pretty strong packs from running them. I dont think it would have been fair to compare to and 8 cell.

Point being they are competitive enough to try and see for yourself.

those label says "DIS 20" but then says [email protected]30Amp what gives

also remarkably all the numbers on those labels are the same. somehow i think they just printed all those labels and just stuck them on

what i meant was 1 pack was matched while the other pack wasn't.....try comparing matched packs against matched packs and you'll have a closer comparison.

Verndog

iTrader: (16)

Yes...that pretty much goes without saying. That is why I noted that one was matched and the other wasn't so people would understand they were not a total fair comparison by matching, but actually are comparable in price.

I'm not going to go out and buy more matched IB's to compare to, so I suppose the other option is to not compare at all, and give people nothing like most of the other responces give to the topic.

From what I'm told, what they do is to match at 20 amps (which gives really good looking voltage numbers and long runtime numbers), then they "CONVERT" (via mathematical calculations) to produce the 30 amp numbers (which is NOT what they would be if MATCHED at 30 amps)... Note that the middle line says 1.28v ... at 20A, while the bottom line says 1.205v ... at 30A.

Not "wrong", just not normal practice, and it tends to fool the new racer... (just my opinion, but I've seen it happen locally)...
