Well, for my system, there aren’t a lot of choices. Do a google search for “Lithium Battery Monitor” and you’ll find about 3 vendors. Since I can’t seem to get Elithion to work, I’m going with the MiniBMS from CleanPowerAuto. While it doesn’t give me all the stats that Elithion does, I very rarely look at them. I note that Electric Blue also has a system now that will give that sort of info, but at $15/battery, that is very pricey for me.
I’m still looking into how to display the SOC (State Of Charge) of the system, and so far, I’m quite impressed with Electric Blue’s system – especially so since I can alter the programming. Will keep you posted on what I choose for the display.
