Hello, I’m new to the forum, and I wanted to create this tread to ask if anyone has attempted to do the extra battery mod on the Mavic 2 by making their own battery packs using 18650 cells. Another question; since the Mavic 2 uses a 4s high voltage battery, should I assume that if doing this mod to my aircraft I’m only limited to use high voltage 4s batteries correct? Normal 4s lipos would not work?
