I have a SmartSolar mppt 75/15 charge controller and I'm wondering how the settings for a 7s19p Lipo 18650 Pack should be. The battery pack is made with Samsung INR18650-35E cells.
I try to made the settings to get a long battery life. So charge upt to 4V per cell? Discarge down to 3.5V per cell? Made this sense?
Currently I made the settings as shown in the picture. So, if someone could say "That's fine" or "Made this setting differen" then this would be fine.
Thanks and best regards, Bernd
