Wire up the connections in parrallel (red-red, black-black) to boost the mAh and keep the voltage.
Wiring them in series (red-black, red-black) boosts the voltage but keeps the mAh... generally not a good idea for LiPo's and other multi-cell batteries, because you want each cell to be 0.1V within each others voltage.
You probably should do some more research on basic electrical theory before attempting anything, because those batt's can easily cause some serious damage to your heart!
As long as the leads of batteries you want to join are of same length it is no problem i use 4s x 3 batt in Parallel. Also check the batteries are charged to same voltage level and there is no defective cell in the packs.
If its any help we are running 3x 3s 4000mah batteries feeding into a common power ring, only issue we have is battery voltage on telemetry reading wrong, but don't know if it's because we have multiple batteries

4c ???
This must be a mistace. Don't you mean 30C? Or 4Ah ?
