If you're already splicing wires it might be smart to put an inline fuse (something like this) between the batteries and controller. The manual for your controller should tell you how many amps it will draw, and make sure your wire is gauged to be bigger than the fuse you use. You want to fuse to fail before the wire does.
You didn't hear this from me, but you can. If you have the 10-30 I prefer that because it has a lower amperage rating, but lacks a neutral. With a GFI pigtail at 15A you can cut off the male end and expose the black, white, green wires underneath. On your nema 10-30 male plug you land the white on the center blade, the black on one of the side blades and leave the other side blade alone. Safe off the ground.
This is not safe because 30A is available and your device is rated at 15A. If there was anything but a direct short this GFI and anything plugged into it will melt and probably catch fire.
Let's make it a little safer. Connect the white like I said, but put an inline fuse at 15A on the side blade instead of landing the hot directly. Connect the other side of the fuse holder to the black wire from the cord. Put in a 15A fuse. There should be enough room in the big plug housing for it to fit. If not have the fuse itself stick out next to the cord.
It technically still isn't 100%. While the low voltage fuse can handle 15A. If it blows it may not actually break the arc. The thing is it has a chance better than not using it and will hopefully save the gfci part of the cord on an overload.
So what are we going to do to make it safer? This is for one and only one appliance, your bike charger.
To make it safer use this fmn fuse holder with this fuse 15A and even 20A is acceptable here, the package I linked has one of each. The fuse holder will need to be crimped to the bare wire and electrical taped over the crimped ends. This will not fit in the plug housing but otherwise should be used instead of the low voltage holder.
If you have the nena 10-50 connect the white to the center flat blade, the green to the opposite bent peg, and the black to one of the side blades, ignoring the other one. Insert the fuse holders in between the gfi and the nema 10-50 plug like I described above.
All this assumes the building super left the power on those circuits. I'd test them first before you get to deep in this project.
