Has anyone installed this Renogy 60 amp dc to dc IP67 charger? It must be very new because I could find only 1 review on it, and it's a 1 star review. Guy says it was DOA. However, I want to believe this is a decent unit, as I love the IP67 rating! It would go under the hood of my Tundra to charge the two house batteries I have mounted in the back of my truck. I know that Victron is supposed to be a better charger, but the Victron only carries an IP43 rating. IP43 rating means "protects against splashes of water that are less than 60 degrees from vertical". Problem with that is that splashes of water never ask what degree or angle they should splash at! Anyway, just wanted to know if anyone has any experience with the Renogy 60a dc to dc charger with the IP67 rating. Thanks!

 

Not answering your question ( i use the 30A one) but a side not. Even with 30A, I have to be very careful with terminals and such otherwise I get heating and eventual disconnect. 60A is going to be a beast to manager. If you need 700W charging due to some reason, I would recommend going to a 24V system and stepping down whever you need 12V

 

I am going adding another battery (that will make 2 total) as soon as it comes in. I have debated whether to run it parallel or in series.

I don't particularly need 60 amps. I like the added amp hours that running it parallel would give and I'd rather not have to deal with the hassle of stepping it down every time I need it. Sounds like I would be better to go with a 30 or 40 amp dc to dc charger. Thank you.
