question

I imagine it will depend what the control panel is doing. Is the control panel is simple turning on other devices? ie turning on an inverter or charge controller (charger like the orion). Then as long as those external devices support lithium then i imagine you're fine. However if the management system itself is doing the charging then you'd likely need to check the manual to see if you can edit the charge profile of the device to work with lithium batteries.

If it's able to take shore power and charge a battery to me that implies that it's doing some charging itself so you'll need to tweak the charge criteria to work with lithium. However if the way it's doing that is by simply turning on an external charger. Then just double check that external charger.

I know the Multiplus has the functionality you're referring to but nothing to say this PMS can't be used with your current setup just have to check how it works.

I have one of these pms 3 units in my camper when I fitted a lithium battery a caravan electrician advised disconnecting the internal charger and fitting a separate charger bought a Victron charger which is wired directly to the battery and plugs in to the mains socket. there is a spare Trip in the 240v side but that’s for the future.

Thanks for the great info guys! Yeah, it's an internal charger and I'm not sure it's able to be modified. So my option is either to add a separate charger for offshore power and disconnect the PMS units charger, or change my Phoenix inverter to a multiplus, and remove the panel altogether, replacing it with a Lynx distributor. Let's see how many shekels are in the bank account. Thanks again!

Just a thought the internal charger works of one of the breakers so just turn it off for now. The PM's unit is nice to have as it contains the 12v fuses for the auxiliaries and switches to isolate everything.

Alrighty, an update from Roamer, the lithium battery company, says this is good to go. He said it will charge slowly from shore power but will get the job done at no risk to the battery. So no need to change things out!

Here are the charger specifications from the PMS. I'll get it all hooked up and will update with my findings in a while. Thanks.

Any update on this? Interested to do the same thing myself.
