Smartshunt accuracy

I have a LIFEPO4 100ah, my manufacturer states it will work between 14.56v and 10v. I know that 10v is not a viable voltage, however at 12.56v its showing as around 15% SOC.

Am I doing something wrong? It's all wired in correctly and seemed to be pretty accurate on my previously lead batteries. All settings change to lipo.

These set SOC automatically when they see correct voltage, tail current for a minimum period of time. After that it's load/charge based until the next time it sees fully charged. Suggest you check these parameters and if you don't see the problem, share them here. What charges your battery?

Does this battery not have an internal BMS? Does it require an external one?

Lithium batteries, for the most part, need to be managed.
