Dc to Dc charger

[Cirrus]

So far I'm very happy with my Renogy 40 amp DC-DC charger.
No problems after a year of use.
Your mileage may vary....

I installed a Victron 30A DC-DC charger in my rig, pulling from the twin 397A total alternators on F350. I've seen 300+ watts out of it which I either use to run outdoor kitchen fridge (90W) and charge the 400Ah lithium bank, or run the 12 CF fridge (500W) while lessening the load on the battery bank while traveling. I put a 50A circuit breaker at the truck battery and ran #6's to an Anderson connector at the bumper. So far completely happy with it.

Sounds like the right way to run DC charging from the truck to a Lithium battery bank.

Has anyone installed DC to DC charger? I have new truck with 220 amp alternator amd plan on putting lithium in my 22MLE. Renogy has one that you buy specific for alternator and vectron just has charge rate. Any experience with these? Tim

Best modification that I've made. Got lots of help with doing it.
