Gives me the capacity i needed!

I have an HOA that does not allow Solar Panels to be permanently attached to the property. To get around this, I manually set up solar panels every time it needs a charge. I like using the Delta 2 Max to power my PC setup, and this extra battery gives me more days between recharges. Given the added convenience, I will be using much more solar in my day to day life. I LOVE the storage compartment, I will never loose the cable with this!
My only complaint is how much solar energy input does not transfer to charging, but I recognize this as a limitation of the technology. I didn't find this information in any of the reviews, so I'm placing my findings here. Of course your results may vary, but I have observed approximately 87% of Solar Input converting to Battery Input.

The battery works very well with my Delta 2. I am using these to run my refrigerator and freezer in my garage. I have installed fixed solar panels that have so far provided enough power to work for most of the day. The automation features and reserve power settings are very useful. I have already been able to use the units to power my refrigerators during a power outage. Great combination.

The extra MAX battery is working great with my Delta 2. I was waiting for EcoFlow to build an LFP extra battery, I did not want to buy the 800 cycle Lithium Ion type which does not match the LFP chemistry of the Delta 2. It would be an improvement to be able to charge the Extra Battery by itself, with solar or from the wall. For our setup, side-by-side, I'd like to have the option of plugging the cord into the BACK of the units (not the SIDE), so they could sit closer together. The ability to manage the batteries remotely with the app, such as Energy Management, is a great feature.

This system is great for my needs, my only complaint is should be an ac cable designed to charge the extra battery separately. Other than that one flaw it’s a perfect system.
