I took my rack mounted battery apart and got the two SLA batteries from the inside. I hooked another SLA battery to them (in series) to get 36v. They are all 12v10ah.
I'm not very experienced with wiring, but my multimeter shows 36v (actually looks closer to 40v) coming out. I plugged it into my bike and NO JUICE! I took the third battery out of the circuit and the juice flows. So I think I've narrowed it down to two possibilities:
1. My battery wiring is bad. I attached a picture of my batteries. Is it possible to tell from this picture where my wiring is bad or does it look like this should work?
2. I think the more likely problem is that my controller doesn't support 36v. I've heard good things about the Ezips from 2008 and earlier supporting 36v (I have the Mountain Trailz 2008 http://www.walmart.com/ip/Ezip-2008-Tra ... ke/8467094
), but this seems to be the most likely culprit. Does anyone have experience upgrading a controller for this bike? Can you make any recommendations? I found this one but I'm not sure if they are compatible: http://tncscooters.com/index.php?route= ... uct_id=177
