Hi guys, first off, awsome forum super usefull. Need a bit of help regarding batteries. Will be buying phantom fc40 soon (Live in south america, rarely go to US so must get purchase right) - also on a bit of a budget what's a better option to buy? 1) extra charger (having two in total counting the one that comes with the phantom) and 3 extra 2200 dji stock batteries (having 4 total) or 2) 2 2700 lectron pro´s and no extra charger? both options cost about the same but was wondering if it wouldn't be better option 1 since I get faster charging (by parallel) and can go back out to the field in no time and have 40 minutes (in 4 different batteries) Also, Is there a way to be able to change the battery in the field without powering out the phantom (as I understand it when you change the battery it shuts down and you have to do the turning on sequence again right? Many thanks!! only have a few days left to make final purchase!!
