Thread necro.

I'm back, and I never actually got around to reviving my Revo. Now I'm finally ready to do it, but I have more questions. I want to run 5s and potentially 6s.

So I wrote a huge reply with all of my thought process in it, but when I tried to post it, I wasn't logged in and I lost the whole post. Figures. The one time I don't copy/paste it into notepad first.

Anyway, what it all boiled down to was this:
My MambaMax w/ BEC was able to handle the Feigao 10XL (1668Kv) powered by a 4s2p 8000mAh 15C battery. The maths on this come out to 120A maximum(?), which means that the truck is geared short enough to compensate and let me MambaMax stay cool and within its current ratings.

If I keep the gearing the same, I should be able to run this HYPERION G3 VX 3300 MAH 5S 18.5V 35C/65C on a MMP, correct? The maths return a 115.5A maximum(?). I should theoretically even be able to run a 6s pack as long as the mAh and C numbers work out to a low enough current, right?

Should I just bite the bullet and shoot for the MMM, and possibly the 4200mAh version of that 5s battery? I'm not sure how easy it would be to get a replacement for my 10XL should it fail or something, so it might be useful to have that extra head-room for a 2200Kv motor in the future.

Is my logic anywhere near sound? Feel free to correct my if I'm wrong at all. I'm a software engineer so I really should be able to understand this crap. Pardon me if it's apparent that I don't. Hah.

Thanks for reading, and I'm sorry for the thread necro, although it is relevant.
