Battery Rating vs Capacity Monitoring
Some things: Shipping batteries in the US requires the Watt-Hour rating to be marked on the battery, and the rule is to use the "nominal" voltage. So LFP uses their 12.8v figure for that 100AH x ...

The shunt gets the amps (indirectly, but whatever) and you can switch that to read watts instead, regardless of the battery capacity.
So for your 100AH batt, 5 amps for 2 hours is 10AH and you are at 90% SOC
If the LFP is 1360 watt hrs and you run a 5 amp load for 2 hrs you should also be down 10% in watt hrs to 1360 -136 = 1224, so the watts read out would have been 136/2 = 68w ??? instead of 5 amps. (I have not tried this with my Trimetric so have no idea what it would say for watts instead of amps)
Same monitor, now the 100AH batt is 1273 Wh and 10% down is 1273- 127 = 1146
so the watts read out would have been 127/2 = 63.5 ???
How does the monitor know that 5 amps is now 63.5w instead of 68w when you change to watts instead of amps? How can the shunt know that?
