Connecting lithium battery via solar, B2B and external battery charger.

[Bill Brown]

I currently charge 2 x 120Ah AGM leisure batteries via a Ring RSCDC30 (B2B) Engine battery and 120W solar panel.
When on ECU the batteries charge via a Sargent EC328 power supply unit.
I want to change the AGMs to a lithium battery.
My questions are; (1) can I configure the RSCDC30 to suit a lithium battery and, if so (2), when on ECU, can I connect the Sargent leisure battery charger output in parallel with the solar panel input at the RSCDC30?
Or do I have to start again in order to use lithium?
Thanks.

I would not advise using the Sargent EC328 Charger with a Lithium Battery.
I don't think the Ring B2B is suitable for Lithium either.

You cannot use the charger in the EC328.
