I think pricing extra batteries the same as the base unit is ridiculous. Just buy another Delta 2 at that price. It's not even smaller. For me unless it's the Max battery at that price it's not a slick deal.

You're looking at different use cases where form doesn't matter as much.

For in home use or camping, bare batteries aren't going to cut it.
Works fine for me for both in home use and camping. In home the batteries literally sit still in a utility closet. The EcoFlow Delta 3 Plus sits there too. In the event of a power outage I have extension cords to run the sump pit, (gas) hot water heater, refrigerator, and my (gas) furnace blower/logic board.
LiFePO4 100 ah batteries weigh less than 25 pounds so they are easy to bring camping. I don't know why you think they wouldn't cut it. They take up less space than the ecoflow extra battery for one with the same watt hours.

IPX ratings, ease of use, and general prevention of people mucking around all come to mind.

Also, what about needing to grab and go in an emergency?
In an emergency I prefer utility over a pretty package. I can fit more watt hours into my vehicle with regular batteries. I can use them more ways. I can charge them more ways. If the EcoFlow generator is being used in one place but access to electricity is somewhere else I can take the batteries separately and independently to charge them while still using the EcoFlow where I need it.
Couldn't find IPX ratings for this EcoFlow Delta 2 extra battery (they'd probably advertise that if they had it) or my batteries, but like I said they are used for trolling motors all the time so they're pretty good around water.
I don't even know how to respond to "people mucking around."

I'm guessing you haven't actually had to disassemble your setup in an emergency.

Might want to practice.

I take it camping. I take the battery to the lake. The plugs I linked before literally pull apart by hand. They are easier to deal with than the big EcoFlow plug. There is no disassembly. You are grasping at straws.

The extra batteries are terrible deals. Just buy any other regular LiFePO4 battery for half as much and a cheap XT60i cable to plug it into the solar ports on the back. You get more capacity for cheaper that way, and you can use the battery with any power station, inverter, or as a trolling motor battery for your boat, etc.
I have read multiple places that its not a good idea to mix battery brands, sizes etc. because of different BMS, charge/discharge rates etc. Sure it works and I have never heard any horror stories but where I am putting these, house, RV, I'm not willing to see them go up in smoke. shake head

The batteries aren't directly connected. It's through the solar port which controls the charging rate. Same thing that happens when you plug in an EcoFlow extra battery (which come in multiple sizes) to a power station (which also come in multiple sizes).
LiFePO4 batteries don't have the "go up in smoke" problem that other types of lithium batteries have anyway. They are much safer and won't spontaneously combust like that.

Thanks for the additional context. I'm curious though since this 3rd party battery is connected to the "solar" port, will the unit actually charge that battery? I would think the unit only expects inbound voltage there and would not be sending charging power out that port?

I don't think so. I use my regular charger to charge my batteries. The battery bank can be plugged in to both the charger and the EcoFlow at the same time. To be honest, the only time I need the extra capacity of the batteries is during a long power outage. The extra capacity lets me run all my critical home loads overnight without running the generator. Nice to not have to go out in the middle of a storm to set up and start the generator too. Then I can charge all 3 up at the same time when I do eventually start it up. Don't have to burn as much gas this way keeping the generator running all day when I can just cycle it on/off a few times to top off all the batteries instead.

There are a couple drawbacks to using your own extra battery:

- assuming you use the DC/solar input on the Delta, it limits input to 8A unless you use an XT60i cable with third pin that ties third pin to negative at which point the current limit is 15A, the max is 600W

- input of 12V battery at 8A is 96W, at 15A is 180W, to reach max 600W input at 15A you need 33V or a standard 48V so you're left with using 2x12V batteries in series or a 48V battery to maximize input

- 600W is about 1/3 of the max output of the unit so if you are using the Delta at it's limit constantly, it will use up the internal battery first and then you're limited by the input of your extra battery; with the Delta extra battery it will balance both charging and power output between both batteries simultaneously and can be viewed from their phone app. If you're using your own battery you'll need a way to recharge them manually.

Note the Delta 2 and extra battery are 48V internally.

I have a Delta 2 with extra battery from the HD deal last year and it somehow ran low enough that it would no longer charge (happened even though it was hooked up to AC power input). I probably could have fixed by opening it up and manually charging the internal batteries but it was replaced with no hassle under warranty but the replacement is a refurb so even though it looks new, the battery capacity is now slightly less than the original extra battery I have.

I've experimented with using both my own 12V batteries with modded cables and solar panels and for ultimate convenience having the optional Delta extra battery can be worth it.

All of the above RayHs posted is true.

- the cable I linked is an XT60i to maximize charging from the extra battery. You can buy whatever voltage extra battery suits your other needs

- I have the Delta 3 Plus which provides two solar inputs, so I don't have to worry about wiring my batteries in series

- I think using the Delta at its limit continuously is a rare edge case, but something to consider if you have it. Most people need the large surge capacity for something like the fridge compressor, sump pit pump, to start a furnace blower motor, etc. The high use item cycles on for a bit, but is off more than it is on. In this scenario my extra batteries have more than enough time to catch up and keep the Delta charged.

Why not at home in the garage or basement - doesn't need to be pretty to switch over a single circuit
