not at home but here’s a YT video of the guy using the latch for ground.

hooked up CTEK overnight and looks like the pic after multiple resets. I’ll drive it for an hour this evening to see if it helps.

Update:
I had a friend bring over a Noco GB40 and @drcollie suggestion worked. We connected the booster and nothing happened, so we pressed the exclamation mark button a few times and the battery and car came back to life. Left it to "charge" for a few more minutes before disconnecting and switching over to the CTEK trickle charger. The CTEK immediately detected the battery and went into stage 2. Fingers crossed it'll continue all the way to the last stage in which I'll disconnect and hardwire the pigtail connector (it's on alligator clamps right now) for convenience.


We have had to do this a few times here at the shop. Never a fun experience!!

I guess i am lucky that the lifepo4 battery in my car is made from a123’s cells. As long as i connect the battery to a trickle charger that puts out 13.3v, the bms will switch off uvp and you can hear the relay makes the sound.

UPDATE - My CTEK charger was giving me an error code on stage 4 as the above picture. I switched over to alligator clamps and now my battery is fully charged. Seems like my comfort access with the eyelets possibly failed and lead to my dead battery along with the combination of me installing the dashcam without driving.

Does anyone who had their battery die now get low coolant warning?

That happened to me also (eyelet cable issue)... replaced the eyelet comfort access cable and it's been 100% since.
