You are looking at the numbers correctly. I am just stating that on track performance is more important than what the GFX states.

Without mentioning brands. I had a brand new lipo for the Halloween Classic and it cycled out great, but after several runs on the track I really did not think it was anything special. So I got out one of my older packs that cycles out much lower and went "significantly" faster on the track. This battery was from another company and had a lot less MAH rating as well. One was a 5000mah and the other was a 3800mah. 3800 was night and day better on the track.

My point is we are not racing GFX's.........

I would also like to note that I think this TP battery will be the battery to beat on the track. They are not new to this game. They're number one in the air.

Hey RBLove, my GFX keeps traction rolling. Do you have any setups tips??

Are there bumps on the bottom to engage the chassis' battery slots?

So, without the bumps, what's the best way to secure the pack? I just use strapping tape front to back, but should I use servo tape or something to hold it side-to-side?

OK, here's another easy one:

I run higher-turn motors such as 13.5, 17.5, and even 21.5. It's clear how a pack like this can benefit current-sucking low-turn mod motors, but can it benefit stock-ish motors as well? My guess is yes -- I would have a much higher average voltage over a 5-minute race.

Make sure you are running at least 200A on both left and right leads, if all else fails turn the C rating down.....it changes from pack to pack......lol!!!

My GFX can kick your GFX"S...ohhh, sorry, got confused as to what we were racing again..

Hey Jason,

I ordered two packs yesterday to be two day aired to Indiana (leaving for the US Open Wheel Champs), can you confirm for me that they are on their way?

Thanks,
Mark Stetler

As far as I am concerned the capacity of a pack means crap. What is important is a standard discharge current similar to what was done previously on NiMH cells. The real important numbers are not Avg voltage at the end of the runtime. We should only be looking at numbers which correlate directly to a race. Meaning what is the voltage at say 1m, 2m, 3m, 4m, 5m and 6 minutes. You could then also avg the data points for each of those times. Who cares what the Avg Voltage is down to 3V per cell.

We are only looking at the Energy needed to complete a race + hot laps. What is the open circuit voltage and then 1 second after the 30A is applied?

I typically discharge my cells on an electronic load programmed with a 25% duty cycle 30A pulse at 2kHz representive of an output of an ESC. This avg current is only 7.5A but it does give an indication of how the cells perform when hit with a high current load. This gives me IR. And yes all test setups differ. Why expose cells to 200A continuosly, what does this indicate nothing.

Now Danny at SMC, and I am not 100% sure had previously stated in another thread he tested at 28A where his packs were rated at 28C. I am guessing that the C Rating was how much current was discharged. Now ThunderPower has stated 40C packs and a 200A load. 40 x 5000mA = 200A

Test both packs at a standard rate say 25A and post the data at discrete times which can give an indication of what a racer MAY expect during a race.

Thanks

Reading all this BS is worse than back in the day when people said Reedy packs were false because the "LAVACO" system wasn't the norm. To me if every manufactor isn't using the same standards in matching then it's all marketing mumbo jumbo. SMC puts out some great cells and has pretty much run away with the lipo trophy. If someone else has come along and has matched or one up SMC then so be it. It's the nature of the beast. As far as finishing results go who's to say who will be standing tall at the finish line? Most of the top dogs have battery sponsors so it may be tough to get TP up there.......then again people switch teams all the time. Bottom line is it's the grunts like me that will be purchasing the batteries anyways so once someone at the club level starts doing well with a certain pack others will take note of that and fall in line. To be honest......out here in Norcal the battery beating everyone is the Reedy 5000 20C Are we racing C ratings or are we actually racing on the track????? Having a variety to choose from is great. I love the internet. How many PM's (good or bad) will I receive over my comments?????????????

You are not reading it wrong. What you are seeing is the variation between different GFXs hence it is impossible to reproduce the numbers.

Superglue the side of your GFX.

The best test of this new 5000 is on the track, has it been run in any major races? How did it compare to the Orion, SMC and other major brands?

We have received several requests asking us to show how our wires exit the case on our cell packs. We put them on the corner edge so that you can position them to be flush on top and side if needed. Several cars have bulk heads and or top plates that may interfere.

That is what I thought was brilliant about this pack...
