I need to replace my R-20 batteries on my scooter. Long story short, I hooked them up wrong and at least one of them is bulding out with a reverse charge, so I think just replacing all 5 would be the best thing to do considering I haven't used the scooter in at least 4 months. The OEM batteries it came with are 5 12V 35Ah batteries and worked fine. However, EVT America as usual doesn't respond to willing paying customers and their support is horrible. Additionally, it appears that they don't sell those batteries that came with the scooter in the USA.

Like many others my controller failed on my R-20, so I replaced it with a Kelly. However, now the battery light will flash when riding the scooter or completely stay off and the range is very small. Any ideas on what could be wrong? Do I need to replace my batteries? Thanks.

My Z20 doesn't have the range it did when new. My odo reads over 1000mi. I'm thinking the batteries are just worn out (or I could have a bad cell). Given how an electric bike works, wouldn't batteries designed to be discharged and recharged be better than those designed to be constantly topped off? Would deep cycle marine batteries work better than what's installed now?

I was replacing my controller and forgot to attached the wire that connects to key on the side of the seat, so now when I use the key to unlock the seat it does nothing. As you can imagine this creates a big problem. I can manage to pull the seat up in the back, so that I can see where the latch is, but where is the release?

If you're planning on using a Kelly Controller in your Z, and you live in a hot climate, hang on to your EVT controller. The Kelly Controller has cooling fins all over the top and sides but none on the bottom. As a result the bottom gets quite warm, especially here in the deep south with temps in the mid 90's daily. I was looking at the EVT controller today and suddenly realized that the top of the controller would make a good heat sink for the bottom of the Kelly Controller.

I wrecked my R30 today and had to go to the hospital. It was a chain of unlucky events, but one link in the chain was a quality problem with the R30.

I had to mail a small package today, so I took it to the post office on my R30. My brakes were being kinda sticky and making scraping noises on the discs. I squeezed them both down hard to realign them, something I had done before many times. This time, the front brake cable burst and leaked fluid. It was useless.

I rode my z20b to work yesterday for the first time ever (a 10 mile trip) and it worked great! It only consumed about 1/4 or less of my battery charge.

But on the way home, I ran into a problem. In retrospect, I think this has been a problem with the bike for a while (before I got the new controller). The problem, I believe, is that the rear brake is clamping down and not releasing. This happens even when I don't have my hand on the brake.

Sounds like I may be having the same problem as "ElectroLex". I have a Z-30 that just quit on me. First it stalled with no throttle a couple of times then quit altogether. The temperature here in Georgia is above 95 degrees during the day and I wondered if heat was a factor. My bike sits in the parking lot all day at work. This problem started in the afternoon on the way home. In late evening after temperatures cooled the bike was running again with no problems.
