Yeh, same as what I do.
Victron quick disconnect on the battery.
Use chassis point as the NEG (not battery NEG)
Then plug in charger when needed......I leave mine in engine bay when charging.
But also have a 3m extension lead for the DC side, but noticed your get volt drop over the cable, at need to tweak the charge profile to bump up the voltage a bit
. Then use the BT app to keep an eye on things, and restart the change of needed.
