Racing battery choices

4s 6000mah for 20 mins makes sense, and when I say 18-19 mins for a 6s 3300, that would be to pretty well 100% DOD. I would only want to run 90% max, preferably 80%, to make room for future capacity loss, and just to give you that headroom if you want to wait a few laps to do a pit stop. But didn't the weight difference after you pitted make a difference in handling?

I never posted the 370 gram weight of the 2250mah pack I was looking at, that's 145 grams weight loss, enough to make a noticeable diff, I don't know.

Probably 2x 3300 6s packs might be the best bet then as far as weight, 2 pits, and cost is concerned.

$300 total for 2x 45C 3300 packs, or
$390 for 3x 65C 2250mah packs... hmmm

haha, yeah I could take my twin Tesla Coils and use them as transmitter and receiver! Although only tapping ~100watts from the circuit might not cut it.

It would if you put several of those coils throughout the track for multiple pulse-charges for every lap.

I left one of the 2s 6000mah packs in the ERevo and removed the other, along with the series adapter - the actual weight change and resulting impact on handling was minimal. The pit was basically removal of a single 2s 6000mah pack and series adapter and replacement with a single 4s 3700mah pack. I only had to mess with one side of the truck for the pit and didn't have to mess with the body at all(just push it out of the way during the pit).

Hmm, that reminds me of an idea I had with the side of the body so I could just lift a flap and swap the pack out without messing with body clips. I made a full under body shield made of Lexan, which acts as a mud guard and skid plate which allowed me to lower the suspension a bit, pretty well a truggy.

Something I just thought of, what do you guys think of a sway bar kit for the Revo?
