Got 2 new Flolreon 5500 mah 3S35C lipo for my 100w LED project, after using them several times I found an issue about the voltage difference between different cells. The max difference I got when I was using it was 0.08v, but mainly between 0.04-0.05. After using it the reading is 0.025.Is that normal or there are something wrong with it? That battery was used only 5 times, and another one has no problem with that(Max within 0.01v). Both of them didn't get over charged/discharged and I storage them when each cell has 3.75v.
