Hello,
I've been riding my new board for a decent chunk of the summer and still getting a few rides in during the fall. However, as of late, I have noticed that my board dies at a much sooner voltage than it used too.
Quick Specs:
6S - 5000mAh (6 separately wired batteries, not in packs)
60A BMS
260kV motor
FVT ESC - set to a 3.2V cutoff voltage
For more info, check this link of my board build:

About a month and a half ago, my board would regularly die at 20.9V. A few weeks ago, it died at 21.9V. A few days ago, I recharged it and when I check the volt meter on my board, the batteries had discharged from 23.9V to 23.5V, then down to 23.0V, then to 22.2V, then 21.9V, and is now remaining at 20.7V... all within a day of no use.
I have no idea what is causing this.
Could I have overcharged my batteries, causing them to discharge on their own?
The BMS supposedly has overcharge protection:

The charger that I use has a red light for when it's charging and it turns green whenever it's been fully charged. I've only seen the light turn green once after charging, and it was about a week or 2 ago. I've always been afraid to let it keep charging as I was afraid of overcharging. I would stop it at 23.9V or 24.0V. It turned green at 24.7V.
I checked all the connections and it all appears to be fine.
If anyone can give me an idea as to what might be going on, I'd really really appreciate it.
Thank you so much,
Mateusz
