I have been taking the kids camping pretty often and the power station we had wasn’t really cutting it. I decided to upgrade to an EcoFlow Delta 2 which has 1024WH and can run at 1,800W output. I also added the EcoFlow alternator charger which is great because it outputs 800W and charges the Delta 2 in a little over an hour. I thought about going with a regular Lifepo4 battery and a dc to dc charger and then an inverter but I couldn’t find anything that would charge a battery as fast as the alternator charger which only works with EcoFlow power stations. I am not saying that a faster charger doesn’t exist, I just didn’t find one. If something does exist I would love to know.
I got the Delta 2 to fit under the rear passenger side seats by removing the JBL amp which I never used anyway. I would like to expand the capacity of the delta 2 using a lifepo4 battery but everything I am finding online talks about taking a battery and having it charge the power station using xt60i cables. That’s fine, but how do I get the battery charged? I have watched so many YouTube videos and they all say expand capacity, yes you are expanding capacity but how do you get the battery charged in order to expand the capacity of the power station? I am really new at this electrical stuff and I know that many on here are very experienced and knowledgeable. I had an idea and would like to know if it would work and if these are the correct parts to use.
Use an AC to DC charger and plug it in to a 110v output plug on the power station and then to the life Po4 battery.
Use a DC to AC inverter from the life Po4 battery to power things like a fridge etc …
Now the alternator charger is charging the power station to 100% in about 80 minutes. That power station charges another battery (not sure on speed though). I use the power station for some things and the extra battery for other things.
Would this setup work? How do I know how much input the life Po4 battery can handle? I would use the highest rated charger as long as I am not overdoing it.
The reason I chose a DC to AC inverter off the battery is because I don’t see any DC to DC inverters. I need to something that connects to the battery for output and then carries the power to plugs.
Am I losing or wasting any power by going from 110v from the power station then converting it to DC so it charges the battery and then converting it back to AC for the output?
Below are the items I was looking at.
Thanks,
Adam
