Hi I have 2x80 watt panel connected through a 20 amp charge controller to 2x 110 amh leisure batteries, the problem I am having is I'm losing voltage overnight, I've even installed a diode between the +panel lead and the charge controller but still lose power. As a test last night I disconnected one battery and this morning the connected one was down to 12.62v whereas the disconnected battery was 12.96v. My charge controller stops charging at 13.5v and starts again at 13.4v any help would be most appreciated .
