If you are looking to keep your options open to charging other batts besides the chargers you're looking at for the specific batt of Yuneec, I bought this one
SkyRC Q200 from Banggood as they had by far the best price. They still have that coupon there (click it) for 20% off, making it $160, but you will need 4 Yuneec adapters to charge all 4 at once. I bought them from this
Ebay guy, but he only has 2 left and you can find them with
China sellers, but the wait for them will be longer.
Of course, this is all from my USA seat, I have no idea if this all ships to Sweden or works with your power. My thoughts were not spending a bunch of coin on a specific batt charger system as it may run out of use and/or a very poor resale value as its use dwindles with the evolution of the hobby.
YMMV
EDIT: The other thing I love about this charger is resistance measurements, along with individual cell. Also App, PC tools and 4 balance boards.
