runtime with a123s
 

how much runtime would i get with 1 4s a123 in my emaxx with mm esc and 8xl motor

not sure on runtime, but you probably would be better off running 2 packs in parallel with the a123 in a biger truck. They really arent set up to handle that kind of load. I tried a 4s1p pack in my LS10 and it was sub par IMO. I got better performance from the running 3s2p than 4s1p.

I also think a 2p setup would work much better.

Or up the voltage.. I saw someone write recently that 6s1p worked well in their e-maxx. I'm about to try 7s1p in my revo.

I run 6s1p, I am happy with it. certainly not underpowered. It has enough power to break shafts and diffs :(
