    So I was checking out my batteries in healthy drones and have some deviations some flights with a battery but then not in some flights with the same battery. Is this normal? I had a 0.103v deviation one flight then none the next. I really don't understand what that means and was hoping someone can chime in that does. Thanks

    Small deviations throughout your flights is normal. It depends on who you ask, but I think the batteries are operating as designed as long as there are not lengthy periods where the deviation is greater than 0.1V. I'm basing that on information I've gathered from reviewing several websites that discussed this topic.

    The differences are related to and caused by internal resistance [differences] of each cell.

    This is known to occur and why 'balancing' is performed during charging.
