LiFePO4 versus standard lithium.

A closer look at the LiFePO4 cell that was in the solar street light.

Plus a look at the protection circuit that matches the different voltage ratings.

LiFePO4 versus standard lithium.

"i get down closer here so you can watch me having a terrible accident" made me laugh so much! Thank you! :,D

"Hilarious but also educational" is the best way to learn.

Hey Clive, Tesla definitely use 18650 Li-ion cells

The answer to the humidity question is YES in this case. Water can wick up into that insulation since they didn't use the good one with glue inside. The ones with melting glue will seal up the connection unlike the one they put in.

I think that's a condition that many of us share. I personally think my cycle just runs toward being up really early. If I'm allowed to follow it I'm quite happy.

You're forgetting that other huge EV market... <a href="https://qz.com/1088195/chinas-booming-electric-vehicle-market-is-about-to-run-into-a-mountain-of-battery-waste/" rel="nofollow noopener" target="_blank">https://qz.com/1088195/chinas-booming-electric-vehicle-market-is-about-to-run-into-a-mountain-of-battery-waste/</a> "The average lifespan of a lithium-iron phosphate (LFP) battery, the dominant type in China’s electric vehicles, is around five years"

I’ve commented on the YouTube video, but thought that here would be ok too. I don’t know of any production electric cars that use LiFePo4, the Tesla batteries are made from 18650’s with LiNiCoAlO₂ (Lithium Nickel Cobalt Aluminium)chemistry. Nissan and BMW etc. tend to use LMO (Lithium Manganese) /LMC prismatic pouch cells. LiFePo4 isn’t energy dense enough for electric cars.

Insomnia strikes, but Big Clive here with the save :) Happy New Year buddy.
