  • Safer to balance charge the pack for the first time. If you don't have a balance charger, fully charge each cell to 4.2V. It's way better to start with a balanced pack because in time it's more likely that the pack will get even more unbalanced. Great video btw, I enjoyed watching! I've done the same operation a few years ago.

    Both lights flash for error, yours were solid meaning the battery was over 80%, look upon the legend. ))

    Never realised I was missing a spot welder in my kit. Will have to grab one now
  • @muzzaball
    Nice job - very professionally rebuilt. That spot welder really is a must for this type of thing. Cheers.
  • @ianjd27
    Great video no one else that I’ve seen explained how the older style makita circuit manages cell balancing.
  • @Yota4Life
    Thanks for the video! Battery companies: "damn they are helping each other! Seal the batteries!"
  • Great video! Just a note: you didn't get a "battery error." The battery error is signaled by FLASHING red and green lights. When they're solid, it simply means the battery is more than 80% full. It happens during every charge cycle. Thanks for sharing!

    this is ingenious!!! i may be upgrading my drill soon the same way. 🤙 you, sir, have earned a new sub👍
  • @ag-om6nr
    Thnx for the tutorial ! It was well done, and you a beautiful clear voice , which was a pleasure to listen to !
  • @TechFIX.
    Best video ever on Youtube for replacing new cells in a makita battery. Thanks a lot dude.
  • @drm42
    Awesome work, well done, but that spot welder costs more than a new Makita battery. It's only worth doing this if you already own a spot welder or you're planning to use one for future projects as well.
  • Brilliant learning opportunity for all of us. Please keep posting. I run a Repair Cafe and what you do really helps us reduce waste, thanks Christopher...
  • @leokimvideo
    That spot welder looks like a heart starter or other fun depending where you poke it. If I was doing this a few photos at the pull down stage tends to really help at the rebuild. But that's just the way I work, especially when I'm ripping apart something new and different
  • @ggguest329
    I'm appreciated that you've made this tutorial as clear as possible, I finally had a full picture about this stuff. Thank you and great job!!
  • @bostedtap8399
    Useful repair, great vlog. Thanks for sharing and stay safe all.
  • @migo-migo9503
    Great video! It was enjoyable watching you put this together. I did learn however that it's definitely not worth for me to fix the battery myself since I do not have the materials and tools necessary haha.
  • @DocuFlow
    Thank you. There aren’t too many channels that have actual real world usefulness, so when I find one, I subscribe and share. Cheers!

    I just got myself a Kweld a few weeks ago. I love it!
