The Juntek could used as a change controller as it incorporates a programmable relay that could be set up to operate to cut off charging at a preset level. Im thinking of doing this for my LifePo4 battery charger where I what to stop charging at 14.2 volts instead of the chargers 14.6volts. See the below link for details.

I guess instead of 230v charger input this could be substitute for a solar panel array.
Check out "Bused_A NZ" on YouTube where he uses a Electrodacus BMS which pretty much does that, uses a set of relays to disconnect the solar panels when the battery had reached the correct charge voltage.

David, could a spare MPPT solar controller be used between the battery charger and battery set to Lithium settings to stop the charger overcharging? My Swift caravan charger only has std battery settings.
I'm also looking at Lithium.

Yes I do agree with you Chris. You will notice I used words like "could be used" as I was not 100% convinced myself. I do like your way of using just a equalizing BMS and then using the Votronic to limit charge voltages. When finance allow I plan to get a 230 volt Victron 30amp charger. Yes David I have tried attaching my 230v charger to my MPPT solar controller put the charger would not produce any output voltage. Maybe it could not see any battery voltage through the MPPT?
