Well, "runtime" varies a lot depending on what you are actually doing. Do you mean 60 minutes on the track or playing in the street?

There's no way some of the runtime/battery results mentioned here are possible if you are talking about racing. I assume you guys are bashing, right? It is a Stampede, huh? :)

For example, the 35 minutes and 3600mah equates to a mere 7 amps average current draw. Isn't that about right for a mini-t? :D

I would say you need a minimum of 10,000mah to make an hour, and probably more if you actually mean 60 min solid runtime and not messin around.

In 1/10 offroad racing some guys are getting 15+ minutes on the new 4000mah+ batteries in mod classes (brushed motors... multiple heats). That's pretty impressive, and pretty effecient for racing. But it's still pulling some amps, let's say 1500mah for 5 min track time. Back in the day we would be dumping with the 1200-1500s at the 4 min mark with 14T mods.

Anyway, 1500/5min= 18,000mah per hour.

There are more efficient setups and some guys have had better results... this is just an example of typical offroad racing, something to compare to.

Bashing is a different deal, and brushless can be more efficient, etc.... like the guys who run 20min mod truck races and use 8000 lipos. One of those guys said once he could run for at least 30 min...

Those are the guys (like craps) that I was referring to, craps runs a Pletty Extreme, which has a kv in the mid-4000s, and he runs 8000mah, getting about 30mins on the track.

Some of these are cheaper per mah than brand name nickel cells.
That's a very good point. In fact, none of my packs (even my new ones) are rated at more than 10C continuous. Two of my packs (4s 6600mah and 5400mah) are 8C. Two other packs I have are 6000mah 10C (2s by Maxamps) and 6400mah 10C (2s by True RC).
Oh wait, I forgot I have a 4s (12.8v) 3600mah 16C pack that uses Saphion cells :005:.
