I have two questions in regards to batteries for my hexacopter using 850kv, running an OSD and gimbal.
1) I accidentally bought a 5000mah 4s, but it has a discharge of 40c. I was told that the PDB would regulate to make sure none of my ESCs would burn out, but could using this battery be a bad idea?
2) Also, any suggestions about how to attach the XT60 deans to new batteries.
-there is an attachment with a photo of the ends of the batteries.
Thank you for your time.

The mAh rating and discharge value would never do anything to "harm" your hexa. It's the voltage which you need to be sure of.
The mAh is the capacity of the battery. 5000mAh is double the size of 2500mAh so think of it as a petrol tank in a car - you can put 20L in or 4L in - it just means you can fly longer.
The "discharge of 40C" means you can safely draw 40 times the Capacity. So, if your motors needed it, they could draw 40 * 5000mA out of the battery which is 200000mA or, in better terms, 200 amps.
As for the real question, 4S. This means your battery is a 4 cell so 4 x 3.7 = 14.8V. You need to know what the motors are designed to work with. Where are the details for the motors? It will say there either voltages or cell-count. It's only from that that would can know if it is safe or not to use.
The same goes for your ESCs - the specs for those will say a voltage rating. There's no sure way to know other than to see what the manufacturer says.
The PDB does nothing to regulate anything - either you misunderstood whomever told you that or they don't know what they talking about.
Hope that helps...
