I've got a Jet2 wheelchair base. The two motors require two 12V batteries. All of the wiring diagrams for the Sabertooth 2x25 that I've seen so far just show 1 battery. I of course have 2. Am I supposed to be wiring my two batteries in series? Or in parallel? or do I just connect both battery reds to Sabertooth B+ and both blacks to Sabertooth B-?
I've read the whole Sabertooth 2x25 manual and all the Jet2 manual & materials I can find. I've already disconnected and removed the brakes in my motors. I know I'm not the first person to use a Jet2 with a Sabertooth 2x25. I must be Googling the wrong words. Help? Links?
Thanks!
I am glad to hear that it is working as well. I have the same motors, and the same Sabertooth for my B9. I have not gotten to the point of putting them in it yet.
I was wondering if any body has tried using the same remote and receiver back and forth on 2 different robots, my lawn mower has a 2x25 saber and my new bot has 2x60 tried to bind to new bot but the light is green but motors will not turn, and I don't know if fan turns all the time because mine don't applied power but fan spins for 3 seconds then shuts down but green light steel on, any ideas 24v system I was wondering if the receiver needs its own power source any ideas any body? And what size of wire recommend using on power leads I'm using 10g, and 12g on motors?

Evidently the sabertooth must use batteries in parallel. Not series. I just fried my 2x32, so now you know lol. The reason in the regenerative properties can't recharge the batteries, then it basically overloads itself in smoke sparks and fire and $200 bucks later ...
Ouch - that's an expensive lesson! How many volts were your batteries outputting in series? I think the max voltage is around 24v or something. But it should be rated in watts because 24v at 50amps would not be pleasant!
I was actually using a 2x32, it can handle 36v and peak amps are about 60. I used a bench power suppy with the same 24v 22a setup with no problems, but the lead acid series had different 'evil' plans lol. (Yes changed dip switch to match battery power ant set everything up in DEScribe)
It should have been able to handle the 24 v and 22amps no prob. There may have been something else that made it it go poof. It's definitely a tricky animal. I read your comment a little closer and thanks for the info about sabertooth handling series or parallel-makes sense.
I had one blow-up on me last year, after investigation, it was related to the Ground reference for the signal wire. Are your saber tooth and EZB powered from the same source? If so how do you have it wired?
Series or Parallel does not matter for batteries, but Dimension recommends an 18Ah minimum for the regenerative system on a 2x25. I imagine this is the factor that determines what you should do regarding your battery setup.
