The 2 pack looks like it comes with 4 batteries, 2 upgraded antennas and a programming cable.
Not bad for the price, especially if those are the high cap batteries.
The antennas are probably fake Nagoyas but might still work better than the stock.rubber ducks.
The programming cable might be a knock off with a Chinese chip that makes finding the right drivers for difficult but maybe not or the drivers might be available either way.
