maxomill Posted January 8, 2018 Share Posted January 8, 2018 Make me clever does someone know how to read these graphs and how do you equate them to a 24 0r 48v system regards Maxomill Quote Link to comment Share on other sites More sharing options...
pilotfish Posted January 10, 2018 Share Posted January 10, 2018 (edited) This is a discharge chart for a 2v cell. If you look at the 1st and last last square in the 2nd data line of the top chart it tells me that a fully charged cell will deliver 5amps for 20hr before reaching 1.8v, so this tells me that the cell has a C/20 rating is 100Ah. Looking at the chart I am guessing that it is probably a Ritar battery, but they come in many shapes and sizes. Battery chemistry and life expectancy would form a very important part of your analysis - A 100Ah/C20 battery with a life expectancy of 1000cycles to 50% SOC is not the same as a 100Ah/C20 battery with a life expectancy of 2000cycles to 50% SOC. Edited January 10, 2018 by pilotfish 20hr rate should have been 0.05C or C/20 Clint and ___ 2 Quote Link to comment Share on other sites More sharing options...
