I could post this is the sprinter forum but I prefer the community here. They might be more helpful on technical details but I’m not there yet.
Short version. I want to charge two 100 Ahr LiFP batteries via my alternator to then provide fast charging to my new Ecoflow Delta2. It will include DC-DC 12v to charge the auxiliary batteries and a dc dc 12-48v to charge the power station van solar charge port.
I’m trying to decide how I want improve the charging speed of my Ecoflow delta2 battery power station. It can charge at 100 watts via a regular 12v car plug.
For $400 and a good bit of wiring Ecoflow sells an 800w DC DC alternator charger. Reviews are not great. I don’t like this options as I dont think it could charge my extra 12 v. Although it would be under the MB recommendation of not exceeding 80A additional load.
The Delta2 also has a solar charge port that has a 11-60v input max of 15 amps and or 500w.
I have an additional 12v 100Ahr LiFP battery.
it seems to me the simplest solution is to add my existing 12 v battery with a 30 amp DC DC charger as an auxiliary vehicle battery. Then charge the Delta2 using the solar port using a second DC-DC 12 to 48 volt converter.
I don’t have all the details worked out yet but the 12 to 48v converter arrived today.
I probably want the option of adding solar charging in the future and want to explore 12v trickle charging of the main starter battery as it drains quickly if you are in and out of the van regularly if it’s not started.
does this rough plan seem decent. Am I missing anything? Should I be up the charging capacity for possible future expansion? Is it way over built? Any features that I am missing?
Thanks EbSP
