You are joking right. You think the rrp gear are going to hold up. I had torn them out with a 7xl regularly. The 2250 is almost twice the motor the 7xl is. If you going to have a chance at a diff surviving you need the 1/8 diffs.
I know you want to go fast. I know you want massive power. If you not welling to spend the money for relible drive train. Please get a video of it.
Don't get me wrong though. I wish you the best of luck. The 2240 was powerful. The 2250 is more motor and you going to have more weight on it.

the GP3300s are really excellent - but the 3700s are best avoided (not as good as the 3300) and the 3600s plain...sucked.

The IBs have a good reputation - i'll do a comparison when mine arrive.

Tom F, you dont mean the old IB 3600's huh? I have heard they were great batteries.

You realize, that this is not going to be an everyday drive?

I'm sure there were some GP3600s - they didn't last very long cos they were very unreliable.

I know for sure they weren't the IB ones - i've only heard good things about all things IB

Even if they are not matched, is $5.95 a good deal on Gold Peak 4300 zapped loose cells, or must I really spend $8.50 on matched zapped ones? I will need to get 36 cells, price will be high ($214.20 unmatched, or $306 matched). I do not race the truck, are matched cells really super important or will unmatched be fine?

dont get the 4300s their voltage isnt good at all.

That does sound good...$6 a cell.

As you said you were just going to be bashing with it - i would run the unmatched cells. They will probably be +/- 3% or something - they will all be pretty close.

For what you're going to be doing you wont notice the difference between 1.18 and 1.21V/cell - the price increase isn't worth it for what you're going to be doing with it.

Extrememods;

You read the warnings from Coolhand and me?

Your drivetrain is like butter for a glowing hot knife like the 2250.

You need 1/8th diffs to keep the driveline in tact... UE cvd's, not the cheap cvd's from t-bonz or what so ever.. it will EAT parts..

Please consider this stated facts, and don't ignore them.

We don't give any negative comment on what you are doing, but you simple don't realize and you don't want to take anything from us? (or at least, we have got that idea)

The GP3300's would be my personal choice too. Matched is nice, in terms of unbalance in discharging.

Go ahead and take the unmatched. But please don't come back saying your truck suck's and it doesn't perform. It's NOT about the voltage the cell's can give, but the current. Unmatched will BURN OUT if you push them over their limit's and can even explode like lipo's can. And trust me when I say the 2250 is amp hungry, it'll smoke unmatched like it was nothing. If you want to take this risk, fine, but I really do not see the point in spending over 800$!!!! on a motor and controller and run some cheap ass cell's to beat a speed record.(laugh's tbh)

Suit your self m8. If you don't want to take advice from post's people been trying to tell you...

I tend to agree - i think something like a 7XL would be more fun - imagine how many more packs you could buy with the money you'd save.

And it's not like that would be a slow set up...

Sneeck - how amp hungry is it?

I'm sure you know more about this than i do, but will it pull that much to weed out the differences in the quality of the cells?

You could always buy a box of like 200 off ebay and match/zap them yourself...

Speed costs money, I would not attempt a speed record project unless I had at least $3000 in funds for it. I have spent over $2000 so far on my jammin crt and it only has a 2240 and 8s lipo, it may take another $500 or more before it is finished, depending how the drivetrain holds up and if I need to go to a 8s2p setup. Remember you get what you pay for, and speed costs money.

I will use UE 8 spyder diffs, mip or UE driveshafts, and matched, zapped GP 4300 cells. Would these help? How did Promod use stock diffs and driveshafts with the 2240 and 28 cells?

I bet he was REAL easy on it and im sure they didnt last long at all. Like I've said, the GPs aren't the way to go. The IB 4200 are the best.

do not take the 4300's, take the 3300's.. It is said here before..
