Question:
Hello, I have a 2022 Thor Tellaro Class B rv on a 2021 Ram promaster 3500 chassis. Originally the RV came with a Balmar Underhood Generator 2nd alternator to charge the 2 x 300ah Lithium House batteries but I have removed that and would like to install a Victron Orion 12/12-70a DC to DC charger to replace it. Do you carry the 12/12-70 yet? Any info or advice would be great. Thanks

We do now Mike and thank you for your patience. We just added the Victron Orion XS DC-DC Battery Charger with Bluetooth item # VN266FR to our website. This is the 12/12-70A DC to DC charger.
The 70 Amp Victron Orion XS Battery Charger item # VN266FR is designed to quickly recharge your house batteries while driving. It has a smart alternator engine shutdown detection feature to protect your ProMaster's alternator. This charger works with lead and lithium batteries and also has Bluetooth monitoring through the VictronConnect app.

I was on the fence between installing the 12/12-70A DC to DC charger over the 50 amp one and I strongly recommend getting the 70 amp charger for anyone who's looking. The slight cost increase has given me some much needed peace of mind.
