Hi everyone. I finally got my first EV motorcycle running and took it for a small test ride down the block. I went about half a block to the stop sign, turned around and started back to my house. I was at about 1/2 throttle, just looking down at everything mechanically moving to make sure everything was good. Then i hear a slight pop, loose power, and some white smoke comes out of my Lifebatt battery pack. I pushed the bike back to the house and pulled out the battery pack. I measured the voltage and still had 52.4 v (had 52.5v when I started). I opened up my pack and saw that the two charging wires going into the pack had some melting of the insulation and there were a couple of components on the circuit board that looked burnt. I think the components MIGHT be able to just be replaced, but I don't trust my soldering skills to do that. Anyone got skills in this area, or know where I can get another BMS from?
I think the root of the problem was that the lead wires coming out of the pack were too small of a ga. I had a whole thread on that on another forum and I was bassically told that I was being paranoid and that the 10ga wire would work for my application and to go ahead and run it. The person who built the pack and put 10 ga wires coming out of it, said it was good for 100a continuously. _______________________________________________ Florida EAA mailing list [email protected] http://www.floridaeaa.org
