I'm considering which package order (p3 or p3 + extra battery)
but I'm wondering how much phantom3 battery.
(p3 combo pack $100 expensiver than starndard pack)

It will be same price p2 battery ($129) or higher?

Anyone who know about this information?

Thanks.

It's not listed on the accessories yet but the difference from the p3 alone & p3 + 2nd battery should be a fair estimate. Although you need to add a bit more mullah as the package deal obviously comes with a discount.
