Racing battery choices

Yea. 30 min is plenty for any race. I feel sorry for the poor Bmain guys that would have to marshal for 45 min. Marshaling a 30 min race sucks bad enough.

I can't seem to click confirm purchase for those Hyperion packs... I was just thinking, since only two races out of 26 races in a season are 30 min, and the other 24 are 15 min each, why not just go for the 65C TP 2250mah packs, for 8 mins a pack, and light weight to boot! 370 grams.

If I wanted to save money I would get a single 3300 65C pack for $170.

I know it might be a better idea to go for the 2600 packs, but I am feeling like what the hell, why not try these things out, and may as well use the C rating and get a small pack right?

Okay, there is the new track layout, they just finished yesterday. It looks like it is a bit faster than the old layout, and not as much tight elevation changes, which I will miss, like reverse banks and such.

JHautz, what would you do, buy two TP 65C 3300 6s packs for $340, locally no shipping... OR get the 3 G3/45C 2600 6s packs for $360 shipped? This is really bugging me.

The Tekno sway bar kit and Tekno RC axle carriers with 17mm adapters are on their way to me now. Hope they give the truck the needed edge to keep up with the truggies without popping pillow balls out at every corner, which is what the Ackermans on the carriers are for. First race this coming weekend.

Just curious, does Mike still sell the hybrid Revo 1/8 diff kit?

Hey guys, here is a pic of my new G3 EX packs! Each pack cycled the first time at 22mohm, 2nd time was 17, the 3rd was around 14-15, so I expect when I start putting a few good real discharges on them the iR should be down to 12mohm where they should be. I ran a couple should test runs only to ~70% DOD and wow do they already have awesome punch, the truck feels more balanced and I notice the weight difference for sure over my old packs. The Sentry balancer is a really nice gadget to have, especially for doing quick pack SOC checking, without hooking up to charger.

Also, I took the lexan plates i had undernieth the double shrink wrap on the old 4200 G3's and noticed they have puffed a bit and have what looks like dirt under the shrink wrap. That must be why they have lost so much capacity and puffed, and pack iR has gone up 50%. Check it out in the pic.

How would dirt creep it's way up into the shrink like that? Seems very unlikely to me.

yeeaah baby, I got 2nd place in Qualifiers yesterday, that was against 5 truggy guys! I had the 2nd fastest lap of ~42 sec, with my buddy in 1st place being a ~40 sec fast lap with a Serpent truggy.

Several younger guys are at the track this year with electric truggies and buggies, and I bite my lip when I see them buying thunder power 65C packs while running an cheap chinese brand motor/esc combo, or a MMM combo with cheapo packs... not to mention they are running these packs to 95% DOD!! Yikes, I am trying to teach them about lipo care and when a good pack/motor/esc combo will get you.

My little 6s 2200 G3 45c packs are running awesome, although I don't like the runtime (8-10 mins) depending how I drive, they are running wickedly cool, coming off at barely warm to touch (didn't temp them), but I would say ~15F over ambient. These other guys huge packs are coming off at 130F (Zippy flight max packs).
