I think I might of “went a little over” (a.k.a. screwed up) with the 4WD rover I just ordered.
I got the bare kit only, no electronics, and I decided to go with dual HB-25 motor controllers, and then of course I went to cheapbatterypacks dot com and instead of ordering two 6Vdc 5000Mah battery packs, (insert brain fart here) I ordered two 7.2Vdc 5000Mah battery packs with 16Awg wiring(upgraded with the heavy duty bars).
I am trying to figure out a couple things:
I am planning on running the battery packs in series (which means 14.4VDC), yet the motors are rated for 12VDC, is this going to burn out the motors?
Will the dual HB-25’s be able to handle this setup?
I know I can change the fuse in the HB-25’s to a lower rating, but as far as the battery packs go, if it’s too much voltage the only thing I can think of is to remove one cell from each pack.
I would GREATLY appreciate any ideas
(fortunately for the rover it’s not going to arrive until next Monday)
It should be that much of a problem. Over volting them will shorten the life of the motors but with only 2.4 v over it should be too much of a problem. And with 2 25 amp controllers you shouldn’t have an issue with drawing too current that would blow those things. The motors in the 4WD1 kit look like they draw 2 amps at stall, also those motor controllers are rated for up to 16 volts so I think you’ll be all set
Thank you for responding. I don’t think I should have a problem, this will not be constantly driving around, and it’s not going to be carrying any heavy on it either.
