Thanks for all the information, Laurent!
It looks like your current model, the PD9270, is a 70-amp unit. Unfortunately, we don’t carry a lithium-compatible converter at that exact amperage.
My best recommendation would be part # PD79RR. It’s a 60-amp unit that’s lithium-compatible, and the good news is you won’t need to upgrade your wiring so it would work with your existing setup.
If you were to go with a higher-amp converter, you'd need to upgrade to a heavier gauge wire, which would make the installation more involved.
Let me know if you have any more questions. I'm happy to help!

Hey Laurent, Did you decide to go with the 60-amp lithium-compatible converter I suggested? I'd love to hear how it worked with your setup, as it could help others looking to make a similar upgrade.
