Well not so fast. That's open cell voltage. You need to load the battery to the rated current. Add in a load resistor with appropriate wattage then you are good to go.
It may not perfect but it gives a consistent reading so that once you get used to what it shows, you will know what you have available in any battery. The main thing is that pretty much anyone can make this from just two components without needing to have any real electrical knowledge and you don't even need a soldering iron if you use these heat shrink butt connectors: Amazon AU: amzn.to/3psV2Oe Amazon US: amzn.to/3G8ufgO
great video mate 👍🏻
