I have a 550 loaded as my signature, Running a 3s 8000mah battery. The voltage starting out fully charged is 12.5 to 12.6. I have the first level set to 11.5 and a load of .8. When I see the first level light flash I land and charge. I am finding myself putting back 7400 to 7600 mah which is to much. What should I tweak in the settings? The protection voltage or the loaded?
