    I am showing a charging efficiency of about 88%. What is the best way to increase this?

    What charge current are you set for? (78A or 80A older models). If you reduce to 48A for example, resistive heading losses (I squared R) would be reduced by 5%.

    Steve, I charge at 40A. Are you saying it will be more efficient to charge at a lower current?
