Efficiency of our batteries
Did some calculations of the results of the Charge to Discharge ratio from the Battery balance I performed last April.
Using the figures for the last charge then discharge cycle (by which time the stick has stabilised with a steady final capacity) gives a Discharge over Charge ratio of about 93%.
Example: Subpack 15, Charged to 7138 mAh, then discharged giving out 6630 mAh, this works out to 92.9%
The test conditions are charge and discharge at 10 Amps, discharging down to subpack voltage of 5.4 volts (0.9v per cell)
