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

[Metallover]

I did some thinking too

5000mah - (5 minutes ^ sikes motor) / the speed of light = exactly 1.6 miles

With my Medusa 2000,MMM,geared 24/58 in an Erevo it takes around 1000-1300mah,of my 4000mah 6s 25c hecell lipos,to go 1.42 miles.Thats doing nothing but speed runs. With speeds of 55+

[trev3813]

Ha, im gonna win with 1.548784 I just know

[lincpimp]

I am also thinking around 10 miles, maybe slightly less. Definately more than 5 miles. I ran my slayer around for 45 mins one day, and walked over 1 mile while doing that. And the tuck made at lest 50 high speed passes on a 1/4 mile stretch, and that was only 5mins or so. The avg mph would be nice, but it must be at least 20mph, so 30min run would be 10 miles...

Is that the Medusa heat sink? It looks like a good one and I'm sure it really helps keep the motor temps in check.

I'm using a Novak heat sink. The Black Bulky type, but it really works good. I run the whole charge out on 4S and I can barely detect any heat with my fingers. Just a tad warmer on 5S with 40 to 50 degree temps outside. The Fan on the Monster isn't even coming on.

Your gearing is a 2.83 pinion/spur ratio. Where mine is a 2.88 ratio. Cool.

Average voltage under load (30mph): 13.5V. (12+15/2)
Average power consumption under load: 200W. (?)
Average current draw under load: 14.815A.
Total runtime at average current draw: 20.25 Minutes.
Distance traveled during total runtime: 10.125 Miles.

What say you?

It's not too late to change your estimate.

Ok, so far we have:

Sikeston34m - 8 miles

Metallover - 1.6 miles

Trev3813 - 1.548784 miles

What's_Nitro - 5 miles

Lincpimp - 10 miles

[FG101C]

I'm game, say...7 miles.

[E-Revonut]

Too many variables!!! What's the vehicle in question, motor, gearing, driving style, etc. In my Losi mini late model I cover aprox 1 mile in a 4 min race (46'x32' carpet track I believe and considering we don't cover the full distance I would est. 1 lap at 100') averaging 53-54 laps in 4 minutes with a lousy setup. 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.

Hehe... OK! I'll go with 9.87654321 miles.

[Unsullied_Spy]

I agree that it all depends on the vehicle. In my Muggy with the 80mm MedUsa, 24T pinion, 40 series tires, and going WOT through grass it'll flatten those 5ks in about 3 minutes and probably only go a few hundred yards. My E-Revo with a Neu 1515 1.5D and Maxamps 8k lipos went 45 minutes one time...that's the longest it ever lasted without breaking something.

If this is in your E-Revo, I'll go down for 15 miles of fairly mild driving

[q8-maxx]

I say 10 miles at 10 mph speed

[mohanjude]

OK I realise this is a 4s thread but my 6s setup - TP 5000 on a Losi 8 truggy with a Lehner 1950/6 and MMM gives approximately 16 minutes run time. Max speed is 46 mph - distance covered average 11 miles. I am trying to work out 0-60 -> it is ridiculously fast acceleration (easily overtook a guy on 500cc motorbike) from standstill. I checked this out with a Garmin etrex GPS.

So depending on driving style about 11 miles is easy.

I'll bet with my setup on 4s,8000's,I could go over 20 miles,12 with my 5000's if I was trying for distance.

Yep it's the Medusa.It's by far the best HS I have.I really don't need it right now,but in the middle of summer it got up to 165 once,so I figured throw it on there. I really like 24/68 for 6s,which just breaks 50,but on 4s it's under 40.I'll probably end up with around 24/62 gearing.

im in too, i guess 11-12 miles
