DJI Battery Charging Hub for Phantom 3 Quadcopter

hey guys this is the DJI the charger that came with DJI phantom 3 professional and it has a connector for the remote and this is the connector for the batteries so you take the battery you plug it in like this and you had to do like one at a time and you're not even supposed to charge the remote at the same time as you're charging the batteries the included instructions basically give you a warning that says don't don't do both at the same time so there's a separate hub that they sell and basically it's just so that you can connect all four of your batteries if you have four batteries together and no charging one at a time which is really stupid I wanted something that will charge them all at the same time not one at a time but basically you just hang your battery off like this so you have multiple batteries you would just plug them in like this side by side I mean opposite each other a
