Here's the situation: I rode my ebike over the weekend, used about 75% of the battery and then stored the bike away, but i forgot to unplug my battery / turn off the ignition to the controller, which left the Cycle Analyst screen on. When I checked the bike about 24 hours later, the screen was still on but it was blank, which was strange. The backlight was still on and I couldn't cycle through any of the menus (everything was blank), but I could enter setup. When I checked on my batteries (12s lipo 10ah) the cells had all drained to less than 2V, some less than 1V. Since these are lipos I am definitely not messing around trying to revive them from this low voltage, I just consider them trashed at this point.
The only thing that could have been draining the battery was my controller or the cycle analyst, I have nothing else electronic connected to them. I don't have a bms, which probably could have saved the batteries. The controller is a 12 fet Powervelocity bought from a member of these forums. But I think the culprit was the Cycle Analyst since the screen was left on for over a day. I am just amazed that the cycle analyst could have drained that much battery in just 24 hours. There was still about 2.5ah remaining in the batteries when I stored the bike, I had only used about 7.5ah out of 10ah total capacity during the ride. Is there something wrong with my cycle analyst??
I realize it's my fault for forgetting to turn off the ignition switch to my controller, but shouldn't there be an automatic shut-off function for the cycle analyst and controller so this doesn't happen and drain your battery to an unusable state?
