I had some trouble on my 3 mile ride this AM.
I started with what should have been a fully charged battery (Calibike 48v 15AH). Bike ran fine until the end, when It was suddenly out of juice. Red light on bottom of hand throttle blinking.
When I got back home (pedaling only).. I checked battery voltage...it was 48v climbing to 50+. I found that if I disconnected the battery for a second and hooked it back up I would have all the light's back up on the handgrip like everything was normal. But one twist of the hand grip and back to a dim pulsing red light.
I noticed that along with the pulsing light their was a tiny spark visible in the plastic fuse holder case, sparking in time with the red light.
I have the battery on the charger now. I checked for loose connections. and didn't find any. I did see one small dark spot on the red wire coming from the battery. Perhaps a heat discoloration? I can't tell for sure.
What preceded this? Last weekend I finished my mileage test. the week before that I rode 15 miles and the battery was in the yellow on the hand grip. I didn't check the voltage. I never recharged it. The next weekend I was able to finish the test. Before I started I took a voltage test and was surprised to see a reading of 72volts?? I rode it and it seemed fine, performed great for 9 more miles. I got to 24 miles before I felt the battery was to weak to continue using. It had some life but power was way down and hill's weren't happening any more. Final voltage was under 48volt's.
I left it as is until last night when I recharged it. About 5 days. Since I popped the tire, there was no reason to charge it. It took right about 3 hour's to recharge it.
I just hooked it up to recharge now that I'm home , and it only took 30 min to get a green light. which is consistent with the battery being charged and functioning right....
Did I kill some cell's? Fry a controller? Burn out my motor on an uphill? I always assist it. Despite the arcing the fuse tests out fine.
whats next?
I just hooked up a voltmeter and I read 55.6 volt's after charging. The voltage is rising as it was in previous check's. This time it's hanging out pretty stable, maybe slowly dropping in voltage.
