I'm thinking of getting the external battery mod on sale at maxx uav with the XT60 connectors for 3s batteries. The actual Battery opening is 1.37" (via the straps) and i was just wondering if anyone knew which batteries would work best to give me some additional flight time.
Ha, I bet you clicked on this post to see how to add another 5 hours of battery time to your flights. Sorry to disappoint you.
There is nothing worse than getting to the flight site, with supposedly all 3 batteries fully charged, only to find out that the only one that is still fully charged...
