Hello! I finally bought lipo!! I got the 4 cell turnigy 20c hard case packs, wired 12s 3p., I bought the Hyperion charger 1410 to charge them. I bought the lipos a while ago, put them on my bike and promptly blew out the one way bearing in the Currie reduction drive. In the mean time while thinking of a redesign, I put them on my kids razor mx 350 (8s2p), and mx500 (12s3p). The lipos make all the difference!! They are amazing!! The first day when I was trying to figure how to make 3 4 cell batteries 12 cell, I screwed up and did the infamous KFF, hurts like hell!! After I got that out of the way it was a lot better. I have ran them on a Schwinn s750 scooter I picked up for less than $50, it is a bit of fun.
So I finally bought a new one way bearing for the bike E, put it back together with the 36 v controller and throttle from the s750, and the 12s battery, and zipped around on it. It was raining but it is so fun I didn't really care, until I was so cold I couldn't handle it anymore. The next day I rode to my nephews to let him ride it. 38 mph downhill with pedaling, on my phone speedometer! about 30-35 on the level ground, it gets along pretty good. Got a flat on the way home. Bad rim strip. I fixed it today and took my kids for a ride in the burley, it pulls them nicely. I think the bearing will fail again, it is simply too small, and not up to the task. It will pull 22 mph with no pedaling and 3 kids up the slight grade. I rode it without the kids up a super steep driveway with no problems, it is so easy to help by pedaling that I naturally do it. There is a bit of a hit or thunk when you throttle up too fast for the slack to pull out of the system, with a bit of a jerk. I really need to upgrade the motor the s350 motor is pretty lame. I have a 63/64 sitting here to go on it, just need a controller. I haven't decided ebike or rc yet. I also have a 80/85 but that will go on my mountain bike. I'll start a build 2 log when I get it going.
Thanks to the forum members for sharing your knowledge, I have learned so much about electricity that I probably wouldn't have otherwise. It is really cool to see each build with another neat idea. AJ with his homebuilt frames, Matt with his cnc beauty, Paul with his amazing welding, tench with his work of art, thud, whiplash, burtie, man its hard to name everybody!! There are so many talented and smart people on here, its awesome!! And last but not least thanks to Justin for keeping it alive.
