EF ECOFLOW Portable Power Station Delta 2, 1024Wh

[arlo]

I would have tried to turn you towards an APC Back UPS Pro unit.
Thing is. Those have a provision for an extended run time external battery. I just happened to have the proper connector for mine.
A couple of local battery warehouse batteries and a plastic food container to keep them in. I can get over 2 1/2 hours of run time.
But you can do that with any UPS. Just outboard the batteries or parallel wire an external set to the internal ones.
Replacements aren't that expensive. I'm due for a new set soon and the local battery supply has pallets of them.
I don't get the whole grounding issue thing though really. Are you saying that a 2 blade plug screws things up but a 3 prong grounded plug plays nice? What about if you hang a 3 prong ground strip and then plug your stuff into that?

Improper grounding and bad electrical connections can cause voltage on the ground and screw things up.
Usually it's two prong outlets that are fine and three prong will have issues if theres a grounding issue. Can be tested by temporarily lifting the ground with a three prong to two prong adapter.

From what I understand the EcoFlow Delta power stations have "floating neutrals" which causes my issue with my H3 only.

Arlo - I swapped out the battery in the APC three years ago, so I was concerned that something else was wrong with the APC UPS. I will keep the unit as I always do and if I catch a deal I will get another battery for it.

As mentioned. The deal would be at your local battery supply house. Not particularly any difference in APC vended and a Yuasa, etc.
As long as you stay away from chinesium.

I spoke with a rep from Schneider Electric in S. PA. some years ago when getting stuff together for a starter solar project.
You know. To get my feet wet and have enough to keep the fridge, boiler, and a few lights on when the juice went out.
To keep from firing up the generator. Besides racking and inverters, charge controllers, connectors. Which he sent me some nice catalogs. I was asking about the deals for deep cycle batteries. A chuckle. There are "No Deals".

He went on. Man, they all last 5 years. Even if you baby them. Maintain them. 5 years tops.
He further went on. If I was just getting into it. Get a good charge controller. And hit the wrecking yards for late model, all the same, car and truck batteries. They'll last.....5 years. So. Hmmmm. Just make sure the inverter is set to shut down earlier than deep-cycles.
I remembered the golf carts in Florida, dudes with trolling motors. Seems like 5 years was tops.
I think I called around and got six close to identical CCA Ford and GM, Mopar batteries from wrecked Diesels.
30-40 bucks a pop. And guess what. They lasted 5 years.

On the sub. of batteries. One of the biggest good and worst surprises was getting a lithuim battery for my HD.
When I installed it. It was like the God of lightning himself sent a bolt directly to the starter when I hit the button.
But parking it with the parking lights on and traipsing around here and there. And then coming back to see the lights off was a big bummer. Like. I never had an issue leaving them on and coming back to start it. Slow, yeah. But it started.
Well. You don't want to bump start a Harley unless you're heading down a hill. Or have a few willing dudes go give you a push.
And they won't start w/o a bit of juice. Which is just what the lithium did. The BMS shut it down cold.
After a bit it recovered enough to give enough pixies to bump it over in 2nd with a push.
I just bought a NOCO lithium replacement. The customer svc. rep. let me know that it would shut down on low voltage. But was designed override it if shut down for a few minutes. Have to check that out when it warms up.
