I know this is a popular meter and I really like it so far for voltage readings and amperage draw and it's tested to be accurate for that but just wondering if the "percentage remaining" part of the shunt is usually accurate?
I calibrated it initially by fully charging the battery and it appeared to work fine for a while but after a couple months the "% remaining" function seemed to be wrong as far as I could tell by comparing to the voltage reading. But reading state of charge using voltage I think is the tricky part with Lifepo4 batteries since the voltage range is small.
I used the Xuba 280 homemade pack with Overkill Solar bms and that performed amazingly well so far and I don't want to ruin it by over-discharging it too much so would like to figure out the % charge thing. I am a total newb at this so don't want to talk negatively about the product it's surely something I am doing wrong.
