I am going to need 2 H-Bridges for my robot, one for forward, reverse and turns. and one for raising and lowering the robot. Do they make an H-Bridge that can do dual functions or do I have to use 2 bridges. I am trying to keep the amount of boards in the robot to a minimum.
Second question is the motors on this robot are 7.2v and I know I can get a re-chargeable battery that is also 7.2v at 3800 mah, I am still tying to understand the voltage thing. Is 3800 mah the same as 3.5 ah and how long does a 3800 mah generally run on a full charge. I see allot of batteries out there with different mah ratings so it would be better to understand these ratings. I don't want to get something that although is the same voltage but a higher mah rating and burn out the motors or the EZ-B
Thanks for the help and just so everyone can see the robot platform I am using here is a video of it.
