100 W
I have a 36V battery, 10 or 14ah, form factor like standard delivery bikes, a Hebb. Paired with a Ezee geared hub motor 350w. Satiator says it is charged, in fact, said that it was over charged to 49v. I don't know why. But more importantly, the battery is fine under no load. I taped the throttle open and the motor ran for 3 hours with the bike hanging from the rafters. But as soon as I tried to ride it, it kicked off after 1 or 2 seconds. This has now happened twice.
Why is this?
I got the bike off craigslist. When I picked it up it would run, I was able to ride it up and down the street, but it only had an extremely low power. I would guess about 30 watts. When I got home with it and hung it up, I found that one wire, the yellow one, had come loose from the JST connector below the controller. When I moved the wiring around, the motor would surge to full power. After stripping away the shrink wrap and some caulk, with the bike hanging (no load), when I reinserted the yellow wire, the bike's power leapt to the full power. Again, at the low power, with the yellow wire disconnected, the system would run. But with the additional power of the yellow wire connected, the battery dies.
Any help on figuring out what's wrong with the battery and how I might fix it would be much appreciated!
