XR+ bms issues
-
Hello, I've been having some issues with my XR+. I've ruled out it being a battery problem with checking cell voltages and trying a new battery. It rides fine until at some seemingly random time it reports low battery and shuts off. Upon inspection of the BMS that I replaced last week to get it running I noticed this.
It looks like an inductor to me, but not actually sure. Does anyone know what part this is and if it could be causing this problem?
Thanks for you time! -
@cheesej Hiya :) That's a 270uH power inductor. If there's actual damage to the windings on it that could cause issues.
The only time I've seen similar when the battery was fine is dodgy caps on the balance IC.
Cell voltages can report incorrectly if any of the caps around the balance chip at the other end of the pcb are slightly detached or faulty. Common to do when unplugging the XT60 and bumping one.Might be worth giving this post a lookover to see if your board is doing similar if the inductor doesn't solve the issue.
