Good day folks! Anyone have recommendations for an alternative to the BV-4113 Motor Controller? Looks like my Dogbot (dog baby sitter bot) requires more power than the BV-4113 can deliver. Oddly enough the Tank's motors in its original form only pulled 1Amp, but when connected to the BV-4113 they now pull 2 Amps, which causes the motor controller to shutdown to prevent overloading. If I connect the motors directly to the 7.2 Vdc battery, they run smoothly and as fast as before.
Thanks for you recommendations! AND DJ, thanks for creating a very cool product !
Yes, thanks for the info.
No problem guys
Why not switch your base to a rad 2.0 base , much less current draw , a little wider but overall about the same internal room , they are cheap I even have a spare one laying around. Or you could find one on eBay. Your treads are close together and I imagine they would scratch up a hardwood or kitchen floor. Rad are rubber tracks.

Hi Dave,
Came across this site: HERE and they have some serious high power motor controllers, not cheap but have some serious grunt. The other option might be to upgrade to brushless motors and use brushless speed controllers. can be got fearly cheap and a massive range available from 1 amp up to 200 amps and at up to 37 volts and some even higher. I'm not sure if they would work with the EZ-B but I can't see why not as they all use a the same kind signal just like servos. They may need slight mods as many come with a built in BEC to power the radio gear.(you just cut one wire). Some have forward and reverse options and heap of other programmable options.
I have one here that I ordered by mistake with out a BEC Programmable Continuously current: 60A Input voltage: Ni-Mh 6-16 cells, Li-Poly 2-5 cells BEC current: no Weight: 35g Size: 58mm long x 35mm wide x 12mm thick plus wires
Price:around $15.00 + shipping

@RichiesRC,
Is that a bi direction ESC? $15 bucks is a very good price.

Kevin I'm not sure if that one is as I can't remember and will plug it in and check for you. But I know you can get them and they are still not very expensive. That one is really for a model plane you really need a car or boat one. You can also get a program card for most of them that makes programming heaps easier but the card I have is for another brand of ESC's that I use in my helicopters. also have a boat one(water cooled) 200amps, pretty sure that one has reverse.

I have brushless controllers but e They have safety features that make you do things like full throttling from controller till you hear beeps then throttled back. Blah blah blah. Is there ways to turn those features off? I have two brand New axi motors2814 10th I believe ,
@jstarne1 That is why I have a program card so you can program it without all those annoying beeps, it has a menu and a digital read out. Can't stand trying to program them via the beeps. But you must get the right card for your ESC as the card below won't work with that 60 amp ESC.
