I am posting a duplicate of the below here in the hopes I can get some input from fetcher and others.
Not totally sure how these forums behave so here is the other thread: https://endless-sphere.com/forums/viewt ... =2&t=92191
I rode battery #3 today into work. I am at <3ah on a Cycle Analyst and already getting down to a lower limit of 42v with full load of 14a. It then stabilizes around 44v while cruising at 8-9a.
Also to re-state, I can't get past 52.7v on a full charge at the moment.
I have lvc on controller at 40v. I was thinking I would ride it home - as far as I can get - to see if I can get the controller based lvc to trigger. If this trips before the bms then I am thinking there isn't a directly flagrant block that is dead i.e. nothing has crashed to 2.5v yet.
In regards to the BMS, I have been able to gather two data points.
#1 - I used a volt meter to find a block that kept crashing. The BMS would trip when the voltage for that block hit 2.5v.
#2 - A friend put the bms on a bench and saw that it cuts off at 33v and then turns back on when voltage goes back up to 40v.
Once I am home, I will open it up and take a look at individual block voltage: at rest, under load, after charging is complete.
Any thoughts/ideas would be appreciated.
