unless yo have very big and powerful gimbals, it will be just fine. Be careful though with long cables. Connecting long cables could cause voltage spikes that is worst case could harm the board. Would be better to use light battery near the gimbal.
Thanks for the answer, that is, you do not recommend using a battery? I stand motors gbm5208-180t, I plan to put on a 2 camera canon 600d and canon 5dm2
Battery is fine, it is just electricity it provides and I am pretty sure it provides enough current for your systems.
Only saying, if you need to use long cables, you should know what you are doing, or there could be problems. If you are installing the battery to the gimbal and using some 40 cm wire, there should not be any problems.
