LL-S review

I received an LL-S as a warranty upgrade. my original LL-2V had a bad cell and these had just come out..... I love everything about it.... the touch screen lets me see the cells are balancing. I do disconnect my panels once a month and let the battery cycle down as living in southern Arizona I'm never under 50%. battery cycles down and shuts off at 19% each month no problem..... glad I paid a little extra and got the display
