  • My application is mobile and will be running off 12V batteries. My question is will the Bigeasydriver be less or more efficient that the Easydriver if adjusted down and assuming they are running small steppers? The reason I ask is I would prefer to have headroom with Bigeasydrivers for future applications, but if there is a noticeable efficiency difference between the two under the same load then I can not sacrifice the battery life.

No public wish lists :(
