Hi,
I want to build my first drone for cruise and long range. I have selected most of the parts in my Aliexpress cart but came about that the battery part is very important and learned that lipos are a bit dangerous and are for racing in general where I'm interested in cruise and long range.
So Li-ions are the way to go but another important topic is that there are different sizes of li-ions as 18650 and 21700 and the most popular.
I calculated the weight = 840g. Where the 18650 @6s2p = 528g.
That's 312g more if I use the 21700. Which one you think I should use ?
