Smart Shunt accuracy

Is SOC more accurate than consumed Ah as a %?

Have been using the smart shunt for about 6 months and noticed that the SOC is always higher than the Consumed Ah as a % of the battery bank total. I.e.: SOC currently reads 77% and Consumed Ah is -114 of a total of 345Ah (66%) in the battery bank. volatage reads 11.86.

Battery settings are top to bottom:

345

13.5

50%

4%

3m

1.24

85%

0.1a

3m

the batteries re Rolls AGM


Thanks

Hi @SimeonS,

try playing with the Peukert value and take in mind that batteries are ageing. So this needs to be adapted.
Consumed Ah is more accurate than SOC.
