       Spent a productive few hours starting to construct the 13S2P 18650 lithium battery pack for my DIY onewheel project. I’m about halfway through. Crossing fingers the plastic spacers don’t make it too much bigger.Buying the cells with welded tabs was the correct choice I think, they can be soldered easily without heating the cell itself barely at all. I’m also using pre-tinned solar bus strip for the jumping connections, not plain nickel. #making

       You may also spot my 4-wire resistance meter setup with Toby, my old Fluke 8840A bench meter (red, black, green & yellow wires). It’s using banana plug extensions in my normal swappable banana plug MM probes. Gets down to 0.03 ohms shorting the probes, not bad for bodged 4-wire setup! I’m using it to check the solder joints in the battery.
