Great run time. Run it for well over 12 minutes, closer to 15. Motor comes off cooler then with 1-cell.
The available energy from the 2S pack is about 15Wh (2.3A x 6.6V). SMC 4900mA 1-cell is 18Wh.
So the A123 pack has less available energy, fast as a 1-cell mod (around a 5T motor) with nearly twice the run time and less motor heat (more efficient). Fast charge them in 15 minutes, dump them to the car stops, out last the life of the car and are SAFE. Conclusion.... Two thumbs up!
hmmm 3S A123 pack in an T2 009
this could get interesting.
This sounds interesting. The bigest problem I see is the same problem we have with lipo. In the lipo beginings racing lipos didn't have the energy density we have today. As soon as LiPo became the new standard and accepted under the rules the battery mfr's started push for a better battery with much higher energy densities. The same will hapen with LiPoFE, and we don't need a battery with more voltage and possibly energy density.
At this point in time onroad doesn't need another battery that has the potential for more power or a battery/motor wind restructure that could hurt on road more than it would help.
