Default LiPo Batteries

Hi,
I just wanted to know if there are any good LiPo batteries other than the Team Orion and Peak

One for sure is the chemistry, the cell we refer to as LiPo are actually lithium cobalt oxide (LiCoO2), LiMn is Lithium Manganese oxide (LiMn2O4). The Manganese is less reactive than the Cobalt so they claim that LiMn is more safe.

Yeah, the LiMn is definitely less reactive than the cobalt. Try doing this with a LiPo...

Notice that he's holding it in his hand the entire time.

Now this isn't saying that LiPo is dangerous just because it's LiPo, just showing that the Manganese is less reactive.

I'm in the process as well of purchasing some Lipo's and saw the max amps batteries. I would aslo like to know if they are good batteries as I can get 2 max amps for one of the Orions so it makes me wonder.

The maxamps batteries are fine. The big difference between them and the Orion/Peak is the casing of the cells. The maxamps are just shrink wrapped bare cells. They're very susceptible to damage and potential catastrophic failure. The main reason to spend the extra money for the orion/peak is peace of mind. If you get T-boned on the battery side in a heat of mod TC at the end of the straight with the orion, you don't have to worry about it getting damaged. With the Maxamps packs, it's a definite concern...

I was just looking at one for practice sessions so I don't wear my Nimh's out. When they become legal for racing I will probably get some team orion/peak LiPo's. Would the balancer be a necessity?
Thanks, Drew.
