Well this is fun!!!
What a great piece of kit the victron smartshunt is, didn't take too long to get it talking to the trusty raspberry pi zero, data getting recorded now so will be interesting to see how closely it will be possible to get it and the smartgauge to agree, right now the SG says 95%. About 22:23 you can see the current draw drop a little when I turned the laptop brightness down a little
Would dearly love to do a proper capacity test but not easy, constant current not so hard with a variable load controlled from the Pi but constant temperature might be a step too far on a boat.
But so far having a smartshunt and a smartguage looks to be a huge step forward in knowing just how tired the batteries are getting on a cruising boat, the 2 agree pretty closely in the mornings with the smartshunt set to 209AH for T105's which suggests still over 90% capacity, over 5 years old so doing OK so far Such fun!!!
