As you know, I have the Mamba Monster in my slash 2wd (ESC and motor), But I am going to get LiPOs, so I need your suggestions for "set-up" the ESC...I already have the Castle Link and everything....:
1-I am going to use 2x 2s, so is the same of one 4s...What is your option on "Cutoff voltage"?
2-If you use "Auto LiPO" on "Cutoff voltage", What voltage you use per cell? 3.3v, 3.4v, 3.5v ...etc?
3-What is the minimum of amps I need for use my ESC? I read somewhere the minimum is 120A for ERBEs but I know those trucks are big and 4x4 so I think is a bit different (lower amps) for my slash 2wd, Right?
I think that's it...
Thanks for reading
P.S.: Here is the link of my slash with the mamba monster:
I would leave auto lipo on...I have my cut off voltage set at 3.4V...120A is right, the ESC will only take what it needs. Get yourself a good set of 2/2s batteries, that should see you right.
Rock n Rolla !
This is a good start..
Just don't buy no name Ebay batts...
2S 9000 x 28C = 252,000 divide 1000 = 252 amps
2S 8000 x 28C = 224,000 divide 1000 = 224 amps
3S 5200 x 40C = 208,000 divide 1000 = 208 amps
2S 4700 x 25C = 117,500 divide 1000 = 117.5 amps
^I run in my Summit.. ^ Requires proper gearing^
( mah x c rating / 1000 = amps)
more amps the better / minimun of 120 amps.
The ESC will only draw the amount of amps it needs.
Higher the mAh the longer the runtime.
For brushless systems 8000 mAh about 45 min & a 5000 mAh about 30 min.
Times are longer for brushed systems.
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.
A temp gun is kind of a must have.....
Hot motor + cool esc = under geared.
Cool motor + hot esc = over geared
Everything warm just right..
Motor ~ 180/190*F (82/88*C) maximum, ideally 140/160*F (60/71*C), temps can be 10*F higher inside the motor
ESC ~ pretty much same temps / Fan comes on @ 150*F (65*C)
Lipo's ~ 140*F (60*C) max, ideally 100/120*F (38/49*C).........
Besure to check sizing before you buy any batteries...
In time some batteries will become discontinued...
No particular order as to good, better, or best....
With larger Lipo battery wires, you might need to - enlarge the exit hole on battery doors....
or run wires out the vents..
