Regarding the GP390SCH we see used by Trinity on their site, the racing (or R/C) battery is EITHER GP390SCHC OR GP390SCHR. SCHC or SCHR are identical batteries. The "R" at the end denotes 'rainbow' shrink as used only by Trinity (USA) and Orion (Europe). It does not mean race. The lack of either the 'R' or 'C' means that it is the industrial version of the battery. Both the GP3300 and GP3700 have an industrial version which are GP330SCH and GP370SCH, respectively. They come in plain green shrink and they are completely different cells than the R/C cells.

What you will be seeing is the new GP3900 'guts' in the ROAR sanctioned GP3700 cells very soon. Orion has had them for weeks and others (no names metioned-LOL) have them now for evaluation.

Kitracer - That was my first car and battery. Was 1990 or so.

Me too Black 1700's were awesome.

Welcome to R/C racing! We used to get new batts introduced every 6 months. It has slowed in the last couple of years with the GP cells being so good.

Its a game of one-up-man-ship.

GP has a 3700, IB has a 3800, GP has been sitting on a 3900 for a few months and now is releasing it to counter the IB cell. IB will probably just relabel their 3800 as a 4000 (it pretty much is a 4000 already) in a few weeks then GP will tweak the 3900 into a real 4100 and so on....and so on until one company gives up....like Sanyo and Panasonic did.

I really don't think they can increase the capacity that much anymore. Since both companies have reached the size limit, they would have to change the substances inside. I think the capacity wars will end sooner than you all believe, and then it becomes a "Who Can Get to 3 Average Volts Soonest" kind of thing.

I think will will be seeing normal size 4000Mah+ Sub-C cells before we all make the switch to LiPo in a couple of years.

No need to relabel the IB3800s. IB is focusing on voltage output not capacity. Lets face it the latest NiMh cells have more than enough capacity for all the stock and 19t classes. Voltage is the key in those classes and IB will keep working on it.

Maybe for stock racing, the hot ticket may be using the 4/5 sub c size cells, that have a typical capacity of 2000-2200 mah.

We were able to make 5 minutes no problem using motors that are equally as powerfull (stock) as used today using 1700's. At least in offroad...

If they truly have at least 2000 mah, I think five minutes would be do-able. A six cell pack of those cells would weight over 60 grams less than 3300's.. so less weight to push around..

The only thing wrong with that statement is the fact that to meet weight minimums, you already have to add weight to the chassis of prolly 75% of the cars out there with 3300's. less weight to push around is not really correct. The thing would be they would more likely be a lot more durable cell(just a hypothesis because it seems the larger the capacity goes, the les durable the battery becomes). I remember when the battery was 3000 MAH, those cells lasted me almost 3 years racing every weekend. Now I can tell a major difference in 3300s after only 1 year. They still perform great but seem to have lost run time a lot faster than the older cells did. I use the same techniques in charging for the past 7 years, 5 amp charge with a .04 cut off.

You know what the good thing is....with these new high capacity cells..that the intelligent racer will realise you dont need a cell with 4000+ mah... i run 3600 mainly because its a intellect and good voltage and the 37s werent available yet.....back to my point 3600s' and good 3300s will be cheap as peanuts now, remember days where i couldnt get much change from $200aud for a matched set (6cell) for 3000s (panasonics)

Can somebody clarify me this:

If GP has not made a press release that state the existance of the GP3900, if in the GP web site there is no reference of SubC with 3900mAh capacity .... how many possibility we have that these Trinity packs are just fake ??

Hmmm... another fine product from uncle Ernie. Just what the R/C industry needs. I love how they are first released as "fun packs."

BTW, original Sanyo yellow wrapper SCs were 1200 as well as 1300 mah. I have a few cells in boxes still in the shop. Funny that we now have AAAs with almost the same capacity as those things, and AAs with more than twice the run-time. Gotta love the rechargable tool industry.
