There’s one option. Or perhaps some of the 8085s, but it might be easier to find mounts for the 63xxx. The width of the hangers you’ll need to run 100mm+ motors is going to be interesting

Hmm… Maybe 6374’s will suffice, I’ll look into the Motors tomorrow…
@BluPenguin Do you think 6374’s will work out for now (dual would push 160A continuous) And then later instead of upgrading the motors and esc just buy the parts for running 4wd and using up the extra amps?
6374s should be plenty for you with that molicell pack. Those cells are over rated on the listing but you’ll have yourself a solid ass 150A pack

That’s how I would do it. I think at a certain point, it makes more sense to pursuit 4wd than to try to push so much power to 2 wheels. Other than the minor downside that the board is slightly less snappy on cornering, you get better braking and acceleration traction with 4wd. It might be even similar in cost for 2 Unities and 4 6374s than 2 massive ESCs and motors.

Good point too. Mooch rated those cells at 30A continuous and 40A burst because they heat up so much at high draw.

Alrighty! I’ll do that then! 2wd 6374 190kv to start…
Interesting…
Does anyone happen to have the thread from the old forum that talks about which cell is best for which usage? I’m guessing the molicell will be my best bet…
I doubt you will ever come close to using half of the amps from a 225amp pack. It seems incredibly unnecessary and you will have huge diminishing returns for the build you are considering. Everything will be more expensive and heavier to take advantage of that much power but will never actually use it.

225a on 12s = 135a on 20s
135a isn’t too bad considering. And you wont need to do all the crazy battery/connector/copper stuff everyone is suggesting.
Or do you plan on doing 225a on 20s??

I think molicell as of now is still the best rated cell in the 21700 category as far as power output and energy density. Marginally better than 40T in capacity too. I wouldn’t go with anything else unless you have enough room for a double stack of 18650s? 12s12p 30Q? That would unleash some hell

12s12p 30q would cost almost 2.5x the 12s5p Molicrll
But with almost double the capacity. The prices I’ve seen the P42s are roughly 2x the price of a single 30Q, (I always buy from IMR) so unless you can source them way cheaper, you could still do a 12s10p 30q which would have 50% more capacity, with same amperage performance as the p42 for only a bit more on cost.
Checking the prices on IMR, You got 30Q @ $3.85 x 120 = $462 for 12s10p, and P42A @ $6.50 x 60 = $390 for 12s5p. So for $72 more you get similar output performance but 30Ah instead of 20Ah.
Just something to think about.

Don’t forget a 12s10p 30Q is 5.7kg and a 12s5p molicel is 4kg; 30% heavier. IMO it behooves you to prioritize discharge amps or range and pick a cell to suit unless you want a very heavy battery.

True, but weight to capacity actually favors the 30q slightly. 5.26Ah/kg 30q vs 5Ah/kg p42. But you’re right, it comes down to whether the goal is a high speed sled vs a lighter and more nimble track board

The 30q Pack is about 1 pound heavier (12s8p 30q vs 12s5p Molicell) The problem is that my enclosure won’t fit its 30q counterpart (12s10p) The max tests is 12s8p 18650 cells which is not enough imo…
Plus with the Molicell I get at the least 20 miles of range (30wh/km which I will never hit) At best I get around 40miles which is enough for me.

Probably better to go with the p42s if range is not a big factor.
That was my thoughts… And that the Molicell pack would be more nimble!
