I got to test out the lifepo4 in my scrt10 against 2 new slashes running gen ace 5000 3s lipo's. Even being down a volt it was no problem winning all the races . I we had to keep the throttles turned down to around 50 to 60 percent to keep the cars on the track. The 3800 easily ran 2 races and started losing power a couple minutes later. It quick charged up to 3400mah for the next race.
So far Im impresed . Ive got an a123 3s2p 4600mah pack coming so we shall see how it compares.
