OK got it.. the 1 degree volt change has an extra 0 in it then the 10 degree volt change .0028 vs .028...
Thats fine. But ill bump or lower my volts when there is a 10 degree change.. Trying to do this @ a 1 degree difference would be maddening..
Now the Trojan site says per cell.. But we dont count all the cells? If so thats good information.. Im learning and thats what I am here to do.. learn..
So I see here that its based on 6 cells. Did not know that.
