Hey guys, so I swear there was a thread solving this from a while ago but I can’t for the life of me find it with the search…
Basically, when I fully charge my board (12s LIPO with BMS) to 50.4v, 100% on the battery meter, I am finding that anytime I try to brake with a load, my VESC will restart until I have used the board a little bit (Down to maybe 98% - 97%) when it’ll start acting and braking normally. Was there a fix for this in settings? Or should I just not fully charge my board?
I don’t know the fix, but I’m pretty sure it is along the lines of the regenatove braking is trying to over charge your battery, but the BMS is stoping it, and with all that extra energy it is shutting down the VESC. I may be wrong, but I think that was what happened to the boosted v2
Looks good to me. Really could be the BMS. Just type “faults” in the terminal tab after the vesc shut down. Don’t switch off the board on between the shutdown and the terminal entry.
Alright I’ll full charge the board tonight and post the error code. Pretty sure that it was throwing up an OVER_VOLTAGE code last time I checked. Thanks btw!
57 is the right number. This value is not to protect your battery. It is to protect the Vesc because it can only handle 60V and by 57V it has a little buffer.
@jackw It is very likely that it is caused by the BMS which shuts down. But please also check with a multimeter that the battery is not above 50.4V without load.
