In my opinion its not worth it.
Not only is the charger more expensive, its also enormous, and it weighs double that of the normal one.
Personally, id save my bucks.
@tomfoolery I just prefer when I can feel the bumps and terrain a bit better. It gives it the agility I felt with my OW original. Furthermore, the range increase is always a bonus, but all in all It just makes the ride feel more responsive..
@ianjohnson you can if its been declared properly, and the cargo plane is certified for transport of batteries.
