@SOC_Nerd @CornishNomad — worth adding that on some of these Chinese packs the RS485 A/B lines are swapped relative to what you'd expect from the label.

@Rob1968 solid thread. Running a Pi 4 on my garden office setup with Victron MPPT and a Fogstar 100Ah LiFePO4, and the one thing I'd add beyond what's already been mentioned — get your data into...
