I know how to program it to have a very favorable character. It's capable of tweaking the battery gauge to function passably with a lithium chemistry that doesn't require a charge voltage higher than the lockout level- and I believe the Valence batteries are such a chemistry. Power seating and auxiliary devices can plug into the system seamlessly, and can take whatever switches I like. For my wife's needs, I think DX2 is great for everyday use- only for sports would Roboteq be a stronger contender. Before I get into these projects we will have to see what 2012 brings.

But I may retrofit all my chairs with the Roboteq as its much more powerful - at least with Odyssey rather than Gel batteries.
Reading between the lines Joe, did you get the impression that they maybe thinking of a DX with more volts/amps?

Ah, well that was a possibility, but I went with 36v and three 42Ah batteries instead! I prefer speed. The roboteq allows that and this increases efficiency a little too.

Burgerman wrote:Agreed. Unless you consider the 50v advantage. That makes it twice as powerful at the same Amps. And its more. It only matters though if you are looking for getting speed out of the system as well as torque. But your wife is light. But you miss out on the challenge of figuring it all out!
