A friend of mine started running his new emaxx with 14 cells East Power 4200 (medium price range). They only lasted a few runs with his stock setup. While running he heard 2 plops. 2 cells were venting.

BTW: He now runs 6s2p A123 with a Neu 1515/1y (MGM 16018). But shifted these components back again to his Mugen Mbx5t since it handles a lot better (no wonder here). But for bad weather runs, the new emaxx is his first choice.

Most nimh cells above 4000mah are way to sensitive when it comes to handling. IB4200 were banned in fall 2007 from racing in norway and sweden due to a few incidents where they "exploded" during charging. My last Nimhs i used were GP3700, which never reached above 3300mAh and dropped quickly in capacity. My first A123 pack still takes more then 2200mAh after almost 100 cycles. Nimhs only deliver good performance when they come hot from the charger. But if you charge them too hot they quickly loose capacity. So: If you want performance you will quickly loose capacity. A vicious circle of death.

Well My friend called Traxxas. It seems they want the motors AND the ESC returned to them. They suspect a problem.

It makes me feel good to see they are willing to stand behind their products.

Way to go Traxxas!

Everyone that I have personally known that has run 7's in their Emaxx has ended up having problems in one way or another. Granted, most of these were in the old style emaxx. I traced my issues back to the plugs, but others have had problems other than plugs similar to those you described.

BTW, I shopped for a long time for a used Hyperion, and I NEVER saw one for less than 75.

I might howver, try some of those ProTek batteries....but I'm a little leary of the low price......

Some people are running the protek lipos with success, but i do not know how much they really know.

I have not paid more than 60 bucks for my hyperion chargers (I have 3) and 2 of them came with balancers, an lba6 and a v-power. Guess I can scare up some good deals, huh?
