5000mah 4S Lipo - How many miles per charge?

When I run my MA 1550mah 2s I put about 570mah back into the pack. So I would estimate mower consumtion to be 550mah/mile. This is using a Mamba25/5400kv, 60/17 gearing, and stock tires. I have struggled with the handling of the car since changing shocks and I'm constantly on and off the throttle at every corner.

The Vehicle in question is this:

Stock E Revo converted to Brushless.

ESC - Monster Mamba V2 using internal BEC
Batteries - 4S Lipo 5000mah 20C - About a year old but still accept 4800mah per charge when using 3.0v lvc.
Motor - Medusa 36-60-2000 using Mod 1 gearing 18/52

Nice Posts Guys! It's amazing to me how motor choice and gearing drastically affect runtime.

Ok, so far we have:

Sikeston34m - 8 miles

Metallover - 1.6 miles

Trev3813 - 1.548784 miles

What's_Nitro - 9.87654321 miles

FG101C - 7 miles

Unsullied_Spy - 15 miles

Q8-maxx - 10 miles

Mohanjude - 11 miles

Asheck - 12 miles

sjcrss - 11-12 miles

Results are IN!

This is VERY interesting!



This run was a combination of grass running and asphalt. I did do a few top speed runs before I settled back into lazy 15 - 20 mph passes. I did bring it in to check it quite often as seen in the "stopped" time of 3:57

This makes total runtime of 31 minutes.

Top Speed of 37.6 mph

I believe one of my next purchases will be a data logger. I wish I had that sort of data to combine with this. It would be sweet to compare motor data along with battery data.

I have the batteries on my MRC Superbrain charger now. I will report back with how many Mah it took to complete this run.

@What's_Nitro - You should have maintained your original guess at 5 miles. LOL

FG101C - You are the Winner with a guess of 7 miles!

The truck traveled 5.8 miles on a charge!

[Metallover]

WHAT!!!

That guy was OVER!!! This is like the price is right,, if you're over yur out man!! I SHOULD HAVE WON!!

jk,,, That's a pretty nice GPS you have. I suppose it's another contest with the data logger. You should take the GPS and see how far you can go on one charge at a constant speed following it in a truck and.....

That's interesting..

Congrats FG101C.

Well here's another interesting tidbit of information.

I do believe my Lipo's have seen better days.

After many bashing sessions and alot of abuse, they have given me ALOT of fun.

I had the MMM set to auto-lipo. After the run, 4S voltage was at 13.98. (6.99 volts per side)

The Superbrain just returned 4000mah to charge them back up.

It's just about time for some new Batteries.

This means 690mah per mile. At this rate, 8000mah would yield 11.6 miles!

Ill take a gander at 2.1 miles.

[What's_nitro?]

Dam.

A little late but nice try Takedown. I got here late also. Wouldn't of won anyways. I was going for One Dollar Bob! I guess that's old school. One Dolllar Drew!

I don't know if you "go for walks" with your rc, but I bet you would get a lot more miles out on a charge. Not trying to make a point just thinking through the keyboard. When I am out walking the dogs I run it a lot differently then when just bashing around the neighborhood. Sometimes you stop it and walk up to it or keep turning it around and bringing it back. Try and climb a bank just odd stuff. I am curious now how far a walk is on a charge. It sure seems like a hell of long ways when it breaks down and you have to carry it back. Another reason to look into getting a gps.

I was gonna say π² but I'm too late.
