I'm trying to put together a system using Victron Smart 12/330 batteries. I plan to use a Smart Protect 220A for load disconnect via the VE Bus BMS V2. I would like to charge batteries with a Multiplus 12/ 3000 and an Orion XS 12/50A DC to DC charger. Do i need a charge disconnect between the Orion XS and the VE Bus BMS B2? Would a Smart Protect or Cyrix LI CT be appropriate? or is it necessary at all since the engine ignition would be shutting off charge? Thank you!
Ive just built a similar system

However, im using a cerbo, it controls both multiplus and orionXS.
You can do it without a cerbo, the multiplus will be controlled over VE.Bus, so that doesnt change. Only change would be controlling the orionXS over its remote input, connecting the allowed-to-charge of the BMS to it.
I guess you could technically use a batteryProtect or a cyrix to stop charging from the orionXS, but thats an unnecessary complication
