I've been searching for a chart that converts battery voltage into a percentage, and have found some for 48v. But it doesn't show what Ah the chart is for. So I'm wondering if there's any difference in voltage between two 48v batteries that have different Ah? I have a Yonglin 80c display where you can set what voltage number you want each individual battery bar (5 total) to represent in the display. If I choose to put the percentages according to the chart I posted, will the percentage level on the display be accurate if I swap between my 10.4Ah and 17.5Ah batteries?
