I have a 200mw vTX could I use a 350mah or 500mah?

Any help would be appreciated?
Where so you mount the battery on the scarab?
I'm using a 400 mW vTX + E-OSD + FPV camera powered throught the balance plug of a 4S lipo. No interferences in the video. I'm using 3 ferrite rings to suppress noise: one at the vTX, one directly at the 12v power distribution behind the balance plug and the third in the 5V UBEC line to the Paris board. I tried a fourth one in my servo line (tricopter), but it did not have any effect so I removed it to save weight.
