Hey guys, now that I've got my 16s 272ah CATL pack together and have put it through a few cycles, id like to do a capacity test, but I have no equipment to measure total current used.
I have the Smart Daly 200a BMS, which in the app shows current be drawn at that time, but its highly innacurate, as I will pull a constant 50a with the inverter, but it will bounce around, from 24a to 67 to 38 to 52, etc. The app does show a battery percentage that seems to be very accurate though, from 100% all the way to 0% (which i believe are based on my LVD and HVD in the settings)
My LV6548 does the same, it shows me instantaneous current, but not over a period of time.
What can I do? I'd rather not buy the little 150w capacity testers, as 14kwh of battery would take way to long and im far too impatient.
Suggestions?
