Can you use a LiPo pack for an entire race, just re-peaking between heats, and the main? (4 min. oval).

If you are talking about the Orion/ Peak 3200, yes you can in 13.5 and 10.5 for sure. Repeaking is all that's needed. After you finish for the night, charge it to about 50-60% capacity.

Thanks, Just what I was looking for.

I've got a Orion 3200 race spec pack, they are saying to charge it at no more than 3.2 amps (2c). Sounds low, is that what I need to do, or can you charge it at a higher amp rating?, or is the 3.2 the best.

Thanks

3.2 is 1c and Orion is in the process of updating there info to 2c(6.4amps for the 3200)
