Hello all. I just purchased a beginner plane and kit. I'm looking for advice on chargers for the batteries. I'm not looking to spend big money until I'm sure this is a hobby I will be sticking with. This is the battery pack I've ordered with the plane, 550mah 2S LiPo Battery 90C 180C 7.4V with XT30. The kit comes with your basic usb charger. I would like to get a charger that charges multiple batteries at once. I live in a rural area and won't have access to electric outlets when in the field. Are there possible inexpensive setups to charge the batteries while in the field? Is it better to just buy enough batteries to last if you are wanting to fly for several hours or is it possible to have a charger setup with enough batteries that you can fly and charge at the same time?
