I cannot afford a 60A Sabertooth.
I just figured it out. It is only one. And, it is a Speed Controller.
I have a Jazzy wheelchair ready to hook up. But, I don't want the whole thing to explode.
thank you for explaining rich.lesson learn
Most wheelchair motors draw 20 amps at stall, so a 2x25 is appropriate, but if the rating isn't written on the motors, then Rich is right, the best option is to measure. Just hook up your multimeter and bench test them. Understand that they'll draw more under load, and much more if they stall (are firced to stop spinning while power supplied by too much load), but it shouldn't be more than double the no-load draw. So, if in a bench test, you see 10 amps, get a 2x25. If they draw 20, get a 2x60.
