Checking in. My rough timeline (I didn't track this very thoroughly):
Sep-2017 - 79% SOH, one bar lost
Dec-2017 - 72% SOH, still at one bar loss
...
Didn't track / post, but lost bars two and three in this period
...
Sep-2018 - 63% SOH, still at three bar loss
Oct-2018 - 59% SOH, still at three bar loss
Some did not lose the 4th bar until as low as 54.98 SOH. Mine dropped at 63.55.
For the record I haven't done the battery firmware update yet. I kind of wanted to drop the fourth bar first just to document it.
Conventional wisdom around here has seemed to indicate loss of the fourth bar around 64% SOH but I'm now well below that. Anybody have any thoughts on what other metrics drive the bar losses? I'm assuming there is some kind of time / distance requirement on top of the direct measurements the battery is providing. Feels like I should have dropped that next bar already. My real world range from 100% down to several miles below VLB is now somewhere in the 70-80 mile range. This isn't going to cut it during the winter for my 67 mile round trip commute.
Hmm... images don't seem to be working. Shared folder should be here though: https://photos.app.goo.gl/hJ8RPakgdu2X5Q138
