I don't think you can "judge" the cost of the battery against the phenomenal deal you got from Wally World. Just take the $$ you saved on the Wally Deal and use it to buy batteries from a reliable source. Don't skimp on the batteries . . . . They are a Single Failure Point....
I realize that and appreciate your input.
I was just hoping someone might have a lead on these batteries that are either on sale or clearance...as I saw the one for a Pro at $45 on clearance at a local store and hoped I might find something similar for the Air. As the cheapest I have found them are around $85 or so.
As for the deal, yep, I only did this for the deal LOL! I already have a NIB DJI 1 (?) and I let my SIL use/have the DJI 3 to help out on his videography.
Anyway, thank you again!
