I wish I could find more deals on A123's I got my first 16 cells for $7.31ea, best I can find lately is around $12/cell.

Good lipos are too expensive to subject them to the sandblasting my trucks get, so the A123's are the way to go IMO. Tough to fit in some vehicles though.

I even converted my MQ SE to 2s 1100mah A123's this weekend the little 1100 cells are pretty sweet for the fact I can charge them @8.8a. I do feel the voltage drop from 2s 1500 lipos though so I either need to gear up or drop in a higher kv motor(medusa 28-xx).
