    Another feature: after a year of use, capacity of LiFePO4 decreases less quickly than the capacity of Li-Ion, so, after a year you are left with roughly the same energy density per mass / volume as with LiFePO4. And the capacity of Li-Ion battery is decreasing still more quickly...

    Love your videos Micah, I rode my ebike in the snow last night, tons of fun!
  • @robotbroken
    I recently purchased DIY rear Wheel Motor kit to install on a mountain bike that I built. I'm saving money now for batteries but have honestly been pretty confused about what I'm looking for. This video helped answer some of the questions that I had. I may try the LiFePO4 route. I look forward to your battery build!
  • @jeremyfagergren
    As always, thanks for the great info and breaking it down quickly and easily. Also, your hair was definitely on point this episode.
  • @Danny_Elite
    Nice! Can't wait to see the next video project using these batteries & then a follow up on how well they work/last long term
  • @CabrioDriving
    You are so good at teaching people. Also a nice person. Great to watch this.
  • @craigcarman354
    Here is my random comment! I already bought three of your books. Thank you for the informative battery videos and books.
  • Yep same, i would love to see a continuation video on your retro E-Motobike build in the near future. I still think its a cool concept that needs to be put on back on the streets. 👍👌😊🚴
  • @donk.5730
    Thank you for mentioning prices, a big help for the DIY-crowd. It makes it more interesting to be part of off the grid crowd. Cheers, DK. . Cheers,...

    To avoid confusion: LiFePo are Li-ion batteries. "Li-ion vs. LiFePo" is only a colloquial distinction, but won't help you when looking for technical or scientific information. It is pretty much the same as the other often used colloquial distinction between "Lipo and Li-ion", labels which were wrongly assigned to pouch cells vs. cylindrical cells (the contents are pretty much the same). Li-ion is the name of all cells that use Lithium to store energy, which LiFePo do as well. The difference is that the cathode material contains iron-phosphate instead of the usual cobalt/nickel/manganese oxides. The rest is pretty much the same.
  • i've been using a LiFePo4 battery on my modded Lectric XP for a short while now, and super happy with it. i switched to this tech for the safety aspect
  • @SMKreitzer1968
    Thanks for the great info, look forward to the build and comparison.
  • @Xtrafix2015
    I just finished second ebike thanks to your video and now making a three wheeler and business is soaring with your help thanks sooo much
  • @chrisbarker270
    Thank you for the info. Stay safe. Looking forward to the build.
  • Right video at right time!!! I have also planning to switch to LiFePO4 from Lead Acid battery for my e-scooter.
  • Love your content! I am planning to build an ebike myself and will use your videos and books as reference :D
  • @pincus321
