Morning All,
I need to remove my leisure battery and get tested as it looks like its not providing enough voltage and is also not fully charging .
I believe i need to first disconnect from the main battery and then should be able to remove the leisure battery .
Im assuming its the red cable here as has a little fuse connected to it as well )you can just about see it in the picture )

I doubt that little red wire is a feed to your leisure battery, if you're really intent on taking your leisure battery out then start with disconnecting both positive and negative of the main battery then disconnect evrything from your leisure battery and dont connect anything back up until you put it all back together.
The feed to the leisure battery should be through a substantial sized cable fitted with two hefty fuses, no offence but if you're not sure what you're doing then better find someone who does, you can cause a stack load of damage if you end up shorting something out.

Thanks for the reply , unfortunately I would disconnect everything and then remove the leisure battery , problem is that this my daily drive as well and will need to use it while the battery is being tested

Ok then you need to determine which is your feed to your split charge system and isolated it before you reconnect your main battery, maybe a photo from a wider angle of your main battery and surrounding connections and maybe someone can advise you on what you ned to disconnect and isolate.
Good luck.

Disconnect ALL cables from the starter positive terminal, then disconnect the +ve from the leisure battery. Wrap that end in tape (even seal inside a plastic bottle) so it can't short to anything, then reconnect the cables to the starter battery. Now you can remove the leisure battery safely.
That red wire does look very small for a connection to the leisure battery. Depending on the state of charge of the LB you could have many tens of amps flowing through it and it will probably get more than a bit warm. At best you could have quite a voltage drop to the LB which could mean it's not being charged fully.
