e-revo 2650 on 3s lipo?

[Kitchen]

i have a mamba monster with a 2650kv monster motor and how fast will the 2650 on 3s compare to the 2200kv on 4s and am i at risk for damaging any thing electrical wise. i have a 3s 5000mah 25c traxxas pack . thanks

check it out in here. not a science but it will give you an idea of what it will do.

i want to think that battery wont push enough amps for the MMM but im not certain. 125 amps is basically the bare minimum recommended but i don't know what they do if they run under.

[Kitchen]

what if i run two of them parrellal? that would double the mah to 10000

[Cameron]

by the math (mah x C)/1000 that makes 250 amp but i don't know if that calculation is proper for parallel or not.

[Kitchen]

hmmm maybe i should just buy some extra packs to be on the safe side lol
but i know on the traxxas packs it says 125amp minimum and 250amp burst for 1 3s 5000

[Cameron]

That just means they are a 25c (50c Burst) pack. Very common.

one 3s 5000 mAh 25c correct

Batts in series double the voltage:
2x 2s 20c 5000mah = 4s 20c 5000mah

Batts in parallel double the mah capacity:
2x 2s 20c 5000mah = 2s 20c 10,000mah.

You can run one 3s... it will be slow like turtle. I have read of guys using one battery for young
(or newboobie) drivers.

change the cell volts....& gearing

2200kv*14.8= 32,560rpm

2650kv*11.1= 29,415rpm

So if you gear it up (to go faster) you should be getting decent track speeds (30-40mph).

Lol I am trying to soak it in guys, so I won't fry my esc
ph yea thanks for the info

[O.G.]

Yea higher math makes me dizzy.
