    Thank you. I always wondered how it could be done

    There are these powerbank boards, which have an intergrated percentage meter. They work great. Not all of them tho.

      Most of them have a gauge in the form of 4 or 5 small LEDs.

    Hello friend, do you have the name of a device that checks the amperage of the entire battery in order to determine for me where the fault is located. I hope you can help me

    VERY INTERESTING. I THANK YOU----NOW IF YOU WOULD ONLY TELL ME THE LOCATIONS OF THE "SUPER DUMPSTERS" YOU GET YOUR SUPPLIES FROM----I COULD "RECYCLE" MORE AND BE PROUD ON EARTH-DAY!!

      Plenty of locations if you know where to look: the Home Depot and Lowe's battery recycling bin, craigslist, curb alert, and the mother of all battery supplies: the electronic recycling center. There are pallets and pallets of laptop batteries, power tool batteries, UPS power supplies, I mean, you name it. Every time I go there, I'm like Aladdin inside the treasure cave of wonders.

    Question I had from the previous video, but when you parallel those boards how does it handle the complete charge? Isn't there something a bit bad about doing that as I have read there is just not on those two boards being done like that?

    • @vuaeco

      They will handle a complete charge just like a single board. The charge curve would follow as normal: full current when battery is low and it will slow down when battery is starting to be full.

    please tutorial to make any phone get battery upgrade using 18650 or 21700 battery cell, that will be interesting to watch.

    What if the battery is actually powering a system that has variable load? The voltage will be different depending on the load. Then your chart is useless. How to measure battery level in this case? Why is nobody talking about this?

    Everytime i talk about lithium batteries to my wife and how awesome they are, i get looked at like im an alien. But thats okay , ill wait for your next video and tell her all about it again hahaha

      Same here. She's polite enough to listen but I always see a blank stare into space.
