John, it is highly unlikely that Technobots will be selling them for high current applications like heavies, maybe for feathers and other applications but that depends on their balancing requirements.

Leo, I see, I did assume 3 packs of A123s and my concern over temperature rise remains. Basically, in my opinion based on my own bench tests from what I can remember as I dont have the results to hand, A123s can just about manage a 5 minute discharge in a freely vented area before exceeding 60 deg C. Their Ah efficiency does not appear to be as good as Bot-Packs so a 5 minute constant discharge is between 10-15C (15-33A). Forget the A123 claims of 35C constant. Bosch machines with a heavy nose drag like M2 need an average 90A for 5 minutes so three A123 packs is border line at best, 4 would be most likely but could be 5 packs if the temp rise in hot conditions was a problem.
