I was going to buy this battery and need to know why it has 3 connections?
One is to power the car and one goes to the ESC for some reason right? What
about the third?

I would contact the company and ask them. It's just a guess but one
plug could be to charge it with? LiPo is picky about voltages, can't
get to high or low. The wire to the ESC is to disable the vehicle once
the voltage gets to a specific level so you don't get below it. There
are some electronics in the pack that monitor voltage and maybe some
other things. This gives you the benefits of LiPo while making it as
safe as NiMh packs.

I think my guess was right. From their website I found "Safe Charge
Connector for use with FMA's Scorpion 2s charger permits up to 3C
charge rate (90% capacity in 20 minutes) "

6400mah 7.4v! To bad it cost more then any car I would put it in. It
is a good to see the technology getting us there though, we know the
prices will come down in time. I can remember racers using NiCd packs
under 2000mah.
