SmartShunt showing 100% when battery is not fully charged

Hey you🙂 I have followed the settings in the smart shut manual for the lithium battery. The only thing that I couldn’t change was the tail current. I don’t know how to do that.

I thought we had been through this, the FAQ is the best advice for the charged voltage, set it to 0.2V below your absorption voltage. Setting it to 13.2V is below your battery voltage so every time it sees low current it syncs to 100%. Read the FAQ and it explains how sync works and why it needs to be higher.
