Yep good point. I’ve downloaded a table of emissivity values for metals and plastics of every imaginable kind and surface finish which should help a bit.
I also used the trusty index finger to check for hotspots and it was all good. I’ll do another test soon with a longer operating period to allow everything to get to equilibrium temperature.
Very pleased with the smart shunt so far. I am tweaking the settings to detect 100% SOC as it has so far synchronised to 100% at not quite the right time. I have a battery voltage setting of 56V (equivalent to 0.2V below Absorption for a 12.8V battery) and a tail current of 1% for 15 minutes. Will see what happens tomorrow. It jumped to 100% too early today so I’ve dropped the current from 4% to 1% and increased the time.
Thanks everyone for all your help and advice. I’m now happy with the SmartShunt performance and will be buying another for a separate circuit with new confidence in how to install and configure it.
Hi, where did you attach the positive cable of the smart shunt?
To the positive busbar.
