Replaced a weak cell

I’ve been wondering why the BMS light will partially light up for the last few months. I’ve been busy, so I didn’t follow up on it.  However, when driving home last week, the BMS alarm went off just before I was about to get on the freeway.  I pulled off to a side-street, and called for a tow truck.  While I was waiting, I started checking batteries, and sure enough – one was sitting at 2.94v, when the others were almost all a 3.3v.

Over the weekend I replaced the battery and now I don’t have the partial warning from the BMS.  (The partial warning is where the BMS warning light just barely glows – it is a standard incandescent bulb. The full warning is when the light is full on and the audible alarm goes off).
