I have a Turbo 35BL and a Millenium Pro. No complaints with either other than no discharge on millenium. Barry White, the 20 amp thing applies to the motor run feature by the way, that means it will still keep running a motor even when it draws up to 20 amps. That is the current problem right now w/ 35BL's and 30's is that when your motor (more likely stock) draws over 13 amps it shuts off hte motor run and says "motor amp too high". I don't think CE would make a charger that can charge at 20 amps...no one would do that...
