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.

There are only 2 motors for raising and lowering (1 per both front and 1 for both rear tracks). I may be wrong so please tell me, but if the R/L (raise/lower) motor in the front is on one of the H-Bridges connection and the rear R/L motor is on the other connection it would be no different then if I set it up like the forward and reverse-correct. Thanks
Yes, sort of... You can only have one Movement Panel in an EZ-B project, so your drive wheels should be a movement panel, and your up down controls will need to be scripted or "servo" controls.

Thanks Alan, what RC one would you recommend, these are not brush-less motors.
I would let someone else make the recommendation. There are a lot of options, and I haven't personally used any yet (I have a Sabertooth 2x25 which is overkill for your environment. A 2x5 would work, but I am sure you can get a better price point.
See this thread for an interesting option: https://synthiam.com/Community/Questions/3475

@thetechguru-I found this interesting thread and I think this is what your where recommending for raising and lowering JAC do you concur. Thanks

Yes, that kind of thing would be perfect. I didn't mention earlier, but you can also use a 4-wire (really 5 with PWM) like the 2.5 amp controller that DJ sells, but it takes 5 digital ports where servo emulation only takes 2 for the same job.
