Oem split charge dc-dc

[T6 DJT]

Hi guys new to the forums after just buying my first van! 2015 T6

Loving it!
Sorry if I’m posting this in the wrong place.

My question to anyone who may be able to help me.

My van has factory split charge fitted, I’m relocating everything to the back as wanting to fit a swivel. I’ve ordered a victron Tri smart charging kit.
I’m in 2 minds about the best way to go about it.
Do I just remove the relay for the oem system under the seat and start a fresh from the battery back?
Or is there a way I can splice into the original cable that goes through to the battery.. lazy I know

Anyone have any ideas?

Does the battery not fit under the swivel seat?

Not as far as I’m aware, as wanting to lower also to bring back down to normal level, other thing was will have 2 battery’s back there with everything in one place

Just leave all the factory stuff “as is” & fit the TR in series with the relay & the battery. I.e. the output of the relay that normally goes to the battery is now the input to the TR. the output of the TR is now the input to the battery. The factory relay effectively becomes an ignition controlled supply to the TR.
