1. Always top balance your cells on a DIY battery pack
2. Calibrate the Voltage with a 2-digit multimeter.
3. For amp calibration, you need a constant source, but fw 19.10 also has 0 Ams calibration.
4. For Victron, [disable float on JK](https://community.victronenergy.com/t/dess-and-float-mode-is-not-a-good-match/20262)
5. Use the settings from this [spreadsheet](https://docs.google.com/spreadsheets/d/1szaRxYzBHxwairtpCBBF4b2ttt4OyZsk8eOQVAYyxSE/edit?gid=0#gid=0) (Specifically, column D, as provided by Andy) as a starting point.
6. Ignore the SoC from JK; it’s rubbish
7. Use the Victron Shunt, forget about JK

I prefer aggressive settings, and the batteries should last 10 years. I hope to live another 10 years and upgrade the packs.
