Default Battery Charge/Discharge Efficiency

I quoted the battery charge efficiency from the spreadsheet I wrote up from a pack refurbishment using Robitronic chargers.

When the sticks had settled in final capacity after at least 5 or more cycles

The final figure would be typically be 90 to 92% for D divided by C, where D=discharge capacity (10 amp rate), C= Charge capacity (also 10amp rate).

This 90% figures applies in the case of a full Charge and Discharge of a subpack, a part charge/discharge may give another figure.
