Guy like George said you can run two batteries together in parallel but they have to be of the same type with the same internal resistance otherwise you will have problems.
Other than that your winch and other high load auxillary devices such as high power inverters should be run of the secondary battery,
The example you made of "you will only be winching with the engine running" is probably right but i have seen in many cases people stalling there engine while winching and not being to restart it..... and jumping it off the secondary battery while in a foot of mud is a lot of ****ing around.
If your finding the winching battery is going flat quickly there are only really three reasons, firstly is your secondary battery ok?
second make sure you haven't got one of these split charge systems which uses a 30A relay!! While winching your winch is probably drawing several hundred amps under heavy load you need the relay to be able to supply all the power the alternator can give to your secondary battery which in your disco is probably 90 amps? to replenish the battery and provide additional power to the winch.
Also make sure the wiring off the split charge system is easily capable of this current taking into account the resistance of the cable due to its extra length!
Thirdly Check your wiring to your winch and two and from the solenoid pack if its been relocated is up to the job! to higher resistance and you end up with loosing power to the winch and putting energy into the wiring as heat...just wasted energy!
hope this helps mate
