Mamba Max in a Savage?

I just emailed Shawn too, he told me it was on your own risk, it is good to go to 4S though.

Just my $0.02: I wouldn't do 5s. At full charge, 5s=21v. The caps alone on it are rated for 25v - who knows what the rest of the components are rated for. That's a bit close to the ratings. It should work as manufacturers figure in some tolerance levels, but you might decrease the life expectancy.

The 7xl draws more amps, I beleive the spec sheet is ~103A or so, too much for a 100A ESC. The 8xl draws ~10A below that, so its ok. A 9xl would be even safer.

I too read somewhere a while back that the MM could do 16, but that is getting really high. The lg caps are 25V, so... Personally I've ran mine /w an 8xl on 15 GP3700 cells and it did great, and did mid 40s. This is only a rare occation I found the 14 cells speed more than enough.

Running on 14 well used GP3300 packs The revo does a touch under 40, so 40 in your heavier savage may not be possible on only 14 cells, tho fresher batts may do it. Dunno. The ESC was fine, but the motor starts getting pretty warm, over 150F, so that's more of the stumbling block.

You will need a fan tho. The esc quickly got upto 140-150F on a single pack of the 14 cells w/o fan. On even a small 25mm fan, temps stayed below 130, even after 4 pairs of packs and hard bashing.

Cliffs:

Yeah w/ the 8xl, but care has to be taken as its pushing the limits of the esc.
