[Electric Boats] Charge efficiency

 

I use a LinkPro to keep tabs on my 8.6KWh lithium battery bank.
One of the features of the LinkPro is a history function which displays the total AH used to charge the cells and also the total AH consumed from them.

In about 2 1/2 years I have put 6209 Ah into the cells, and consumed 6116. That works out to a charge efficiency of 98.5%. I was amazed.

Does it really matter? Not to me, since I charge from the grid, and pay little for electricity here on Puget Sound.

But I thought it was interesting.
