That's what I figured. According to the manual, it's sampling all signals every 100 milliseconds. At that rate, it's hard to image that the BMS wouldn't be calculating a relatively accurate mean. I'll keep a close eye on SoC values vs. rested voltage values and hopfully things don't start drifting apart.Most battery monitors are counting Coulombs. They do this by mathematical integration. The algorithm is going to take samples which are both low and high current on that curve, but they will all average together. So any well designed battery monitor should show accurate values.
Though some BMS have a SOC monitor feature, it can be inaccurate, as some have this feature kind of slapped on at the last second.
So, fingers crossed this is all 'normal' and I just need to ignore the readings displayed on the BMS software...
Thanks everyone for the quick feedback on this.
