I came across this article about DIY Power Wall in Japan.
What I have
・Multimeter
・PC battery
 
Welcome! you will need more then that :) Have fun.
 
For testing 18650's you need a capacity tester such as the Opus BT-C3100/3400, for more in-depth information look up wolf here he has done some awesome testings of many tester.
To test larger cells or packs The Icharger line of chargers would be good to have the x6/x8/x12 are all capable testers as well the other models in the icharger line . (Capacity and IR)
An IR meter can come in handy ( almost a must have) I have an YR1030+ Wolf has also tested many IR meters.
Cell holders if using 18650's 26650's Cylindrical cells.
Bus bars
Battery tab spot welder /soldering iron (large tip)60-100 watts
Lots of time (18650's)
Prismatic cells also take a lot of time (capacity testing) but are faster to connect togather/ install BMS.
a good BMS
later floyd
 
Well... it's a good start :) Now I'll just turn over to look at my desk and I will tell you the first tools I started with: multimeter (yes), notebook battery (yes). After that the first things I got (for cheap on AliExpress:love:, Ebay and Amazon): a cheap soldering kit; a nice mat to not ruin my desk; good wires; a power supply unit taken from a dismissed PC; a bunch of small displays and battery meters (to display Volt and Ampere)... and some other batteries. Ah, and a good overdose of videos, tutorials and guides.
