Things to be aware of before installing diyBMS - stuartpittaway/diyBMSv4 GitHub Wiki

This document is intended to emphasise things you should be careful about :

1. Make sure you don't invert the polarisation towards the battery, if done the module will break.
2. When daisy chaining the module tripple check that you connect TX -> RX -> TX etc. and NOT TX -> TX since the chance of breaking module are VERY high.
