Upgrading '87 RV with LiFePO4 batteries, Li capable converter & solar panels

[Chaz3664]

Hello, I have an old '87 RV I use for hunting and am upgrading the (2) 12v 100ah lead batteries to (2) 12v 100ah LiFePO4 batteries. The RV has the original converter (TU-730-2) so I know that has to be upgraded to properly charge the LiFePO4 batteries. I am considering the Progressive Dynamics PD9130LV (30-AMPS) model. I also have several 100watt solar panels I want to tie into system. Question is do I still need to upgrade converter if I buy a Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller? I will still need the ability to plug into 120v shore power when using AC and camping with hookups occasionally. I apreciate any insight and suggestions. Thank you!

Just because a charger doesn't say lithium compatible doesn't mean it isn't.

Do you have a manual or know the charge voltages?

The Victron is only for PV charging.

The PD9130LV is Progressive's Lithium converter. It might be OK but it doesn't allow you to see or change parameters. I personally would use a Victron charger also so you can see the settings for it and the MPPT controller.

If I understand you correctly, I could keep the original converter with battery charging leads disconnected and use Victron charger instead for more reliable charging?
