The best power settings for my battery

Hello everyone, after few test with my drone I finally have a stable flight and now I want to use with the maximum efficiency my 6S batteries, I have two 6S battery with 100c costant and 10000mAh in total, in the power parameters what minimum and maximum voltage I have to write for maximum efficiency and reliability? Now I have maximum 4,15V and minimum 3,6V. Is that ok or I need to modify something? All the power is from the power module so I have the mah comsumption and I write in the parameters that I have 9500mAh in total for security, but I don’t know if trust it or not, here my last log and a picture of my drone. Thanks to all :smiling_face::smile: ( in the picture I had the 4S batteries)
