I have not heard of a battery monitor needing 6 cycles to get it correct, but new batteries do need cycling several times before they are at their designed capacity.

I think the monitor is a bit too basic, built to be a price leader not the most accurate monitor available. There is not a setting for Peukert, which it claims the monitor learns but I doubt it can do this accurately. All the battery monitors I have installed - Xantrex and Victron - require an input for Peukert. If they can't find it for themselves I doubt a less expensive monitor can.

I think you get what you pay for. I recommend the Victron BMV-600 as I know it to be an accurate monitor and at $149 from Jamestown Distributors it is a real bargain.

Fryewe - you state that you have told the monitor that your battery bank is 100 AH - that should be set at the total AH of your batteries, somewhere between 200 and 240 AH.
