I have a 72v 15a Li-On battery with a CRYSTALYTE M3540 and CAv3.
My issue today is that it seems to believe the battery is draining at an alarming rate and shuts off very quickly (less that 2 mins of running or about 3 seconds of max draw from throttle) but when I replug in the battery the CA reads the normal starting voltage (82.5ish) and will run again happily for a few moments then the voltage will drop off very quickly (10v per sec or so) and it will shutdown again. This is with a fully charged battery and after the short run nothing seems warm. I have also checked all the external connection and they seem fine. The one that was loose previously has been reinstalled and is in place. The issue is occuring while dry running the bike so it is unlikely something is getting bumped out of place.
Any ideas what is wrong/how to fix the issue?
Here is my old thread about a somewhat similar issue with my bike -- http://endless-sphere.com/forums/viewtopic.php?f=2&t=67917
More info: When the battery is removed from the controller while the controller is still on I see the exact same reaction as the issue I have described(obviously not while the bike is running, just turned on). This would seem to imply something inside the battery is turning off?
