Orion does not use the Lavco anymore....its a modified Turbomatcher system that puts on a Variable load to simulate race conditions, hence why you often see numbers that look a little higher....
It works for them though, as they have done pretty well on the racing scene over the last couple of years....
A 501 cell at 30 amps is not unheard of anyways.....I have seen 430+ cells, which is easily over 500 seconds at 30 amps on a regular turbomatcher....
