Yes, safe as long as you have done it neatly and the wire cannot chafe on anything (really you should have a fuse at each end, right by the battery terminals) and the wire is good for a bit more than 40 Amps.

You have done what I would do ;)

Plenty of split charge relays on Ebay.

Pull the fuse out if camping up so you don't drain your main battery ;)

PS, just re-read = you don't need the cable from -ve to -ve, but it won't do any harm either.

Halfrauds would do one as it will be just a standard relay if you want one sharpish. Just remember that they will find a charge level together so if your leisure is discharged and you link it to the crank battery then you may not have a lot of power to turn ya bus over with. Also most leisure batteries ( depending on construction) do not like to be discharged in the way starting a camper does. :?

some of your engine cranking amps will be drawn through your cable as both batteries will be starting the engine. Depending on the state of your connections to your starter and the level of charge in your leisure battery this can vary. It is better to isolate the batteries until the engine has started. However this is no different to how most people have their relays set up (with the relay being triggered by the charge light) without issue. If your fuse is rated lower than your wire you should be fine.

But ^^^^^^^ the relay doesn't actually switch and connect the batteries UNTIL the engine has started. :ok
