dewalt 14.4 battery help

[newbiecrawler20]

hey everyone.i have a 1/8 new bright avalanche with 2.2 mudslingers that I'm going to be putting a Dewalt 14.4 in with the summit transmission.what battery would be best.ill be getting a 4s5000mah or bigger but i don't know what c rating ill need for this motor. 20c..30c..40c so on and so on i know i don't have a summit but i think the summits are the only one with the Dewalt motor.thanks in advance

well really 20-30c should be fine,

I agree with the above, don't go below 25c with the Dewalt and you should be fine.

yeah anything more and your gonna really shorten that motors life.

thank you very much everyone.ill check into some 25-30c batteries.what kind of run time could be expected with that motor on a 5000mah anyone know?

The mah rating directly correlates with the C rating of the discharge. For instance a 4s5000mah20c pack can nominally put out 100amps at the rated voltage, whereas a 4s1000mah20 can only put out 20amps. Depending on esc, about 50amps on tap for that motor should be ok. Brushed motors don't draw much.

The amperage rating of a lipo pack doesn't affect motor life as a motor/esc draws amperage, the voltage can affect motor life if a motor is rated for a lower voltage than what is applied. Not applicable in this situation though...

after 2 hours of research i now understand everything you just explained.thanks again everyone for the help

Expect 30-40 minutes of runtime
