Is it too early to tell which 1 cell pack will be the hot ticket for the upcoming winter season? Assuming that all the currently (or soon to be) available 1 cell packs (SMC 40c&50c, TP40c, Reedy, Epic etc) gain ROAR approval come Oct 1st. Has anybody had a chance to do any real life testing using either cycle numbers or even better track testing to compare any of these packs? I hope this doesn't turn into a "My sponsor's pack is better than your sponsors pack" conversation for the sake of us low budget racers that are waiting for the dust to settle before deciding what to purchase for the upcoming winter season.

Hey Bob, I agree with you it would suck if it did turn into "my sponsors pack is better than your sponsor pack", heck it is already going on with chassis "my sponsors chassis is better than yours". Thanks Scott

I can only speak for the SMC single cells but I have tested the 40C and 50C back to back to back to back on the track in 12th scale onroad. I dould tell ZERO difference in them on the track. Cycle numbers were all so close that by looking at the numbers you couldnt tell which was 40C and which was 50C.

I think a lot of guys get to caught up in the C Rating game. Also on that note I could tell a big difference in an older SMC Single cell pack (24C 4000) and the newer 40-50C packs. About .3 a lap average faster with the newer stuff.

I was talking to Sean C the other day and he had just gotten the Reed Single cell pack and we talked cycle numbers and they were pretty much identical as the SMC's. But that is on different machines on different coast.

"But, my Sponsor's brushless motor is way better than your Sponsor's......":wave:

...because I say so.

Thanks EA. Good info. We need more real life data like this instead of arguing about what is printed on the label of the pack. :thumbsup:

In head to head comparisions that i have done there thunder power kills the smc in the first minute. The TP pack holds 4+volts at 35 amps for over 60 seconds and the smc 4900 40c on 35 seconds.

Based on Frank's numbers, the SMC 40c and 50c look pretty darn close to me. Certainly close enough to tone down the uproar of a new 50c coming out right after a 40c pack.

I think for those that bought the 40c packs, you shouldn't worry too much about the guy beside you running the 50c pack.

Tour already addressed this for us. they will be in contact with the battery companies to get part numbers on the batteries that will be legal.

trinity and reedy will have a 40c battery. but i would guess all 4 or 5 batteries will be very close.:thumbsup:

I've had the oppertunity to cycle 5 TP packs and only one SMC but I assure you that ALL 5 TP packs hold 4+ volts for between 62 and 72 seconds. Granted I have only had the chance to cycle 1 smc but it didnt hold 4 volts for more than 35 seconds.
