Hi Phil etc
That’s very interesting that just normal charging ternary NMC cells that are
dead at/below 2V per cell can cause a fire due to dendrite growth shorting out
the plates.
Your video showed Tesla using these cells in their 12v aux batteries on new
EVs. Sounds like Tesla screwed up and should use LFP cells for 12v battery
replacements like everyone else
Do LFP batteries have the same problem if a dead cell <2V per cell is normally
charged? I’m sure I’ve done this in the past with LiFePo4 cells without
thinking about it (mostly small battlebots). Don’t recall running into this
when I used to convert EVs using Calb or Thundersky LFP cells (since EVs didn’t
sit to long without being charged)
Stay Charged,
Mark
