?SW sunshine =⚡️⚡️lit up thru the darkness✌️
I just received my new delta 2 and 220w panel this weekend. I charged to 100% and did a discharge cycle test using a 1100w heat gun bring it down to 0% soc.
This was less than the draw Will did on his review on YouTube video. And he had no trouble with recharging immediately after.

At that point I began to recharge from grid power and the unit would not start charging. On the screen it showed the flashing battery failure icon and the over temp icon beside it. Tried to turn off and restart several times with no luck, would not charge. At that point I figured the battery was too hot and the over heat protection kicked on. I left it connected to the grid power and went to bed.
In the early morning I checked on it thru the app and it was taking a charge but at a greatly lower wattage than it was set for.
It got to 100% SOC I then unplugged the grid power and ate breakfast.
Checked after eating and saw the display was down to 94% SOC??
Did another discharge cycle at 200w til back to 2%SOC which I set in the app.
I then recharged at 800w til 100% SOC.
Which it remained at and didn’t drop. I
ran it again on another 200w discharge down to 45% SOC then recharged again to 100% SOC. Which it remained at over night.
Today I connected the 220w biracial panels up and ran another cycle at 200w discharge off on on clouds. Panels produced up to 215w when the clouds passed then down as low as 15w in cloud cover.
Ok at a 200w discharge I was running the delta 2 was in the shade and outside ambient temp 78deg I checked the app and the battery was at 106deg!
Called Ecoflow line and was told temps should not be that high.
200w is a relatively light load from a portable evap. Cooler box.
CS said maybe I need to unplug load and let it rest??!?
Big concern at that point!! What if it’s powering a small fridge during power outage?? Unplug the fridge because the delta is getting hot?? At 200w?? ?
This unit the delta 2 is rated to easily carry that small of a load, it’s rated to 1800w.
I’m thinking I may have a defective delta at this point. Called Ecoflow and was told they would reach out by email but I’ve heard wait time can be lengthy.
Anyone else checked and tested their Ecoflow delta 2s and experienced this hot battery issue?
Sorry for the long post but I’m trying to cover everything.
Please let me know as I’m ready ask for a replacement. It was bought on Amazon during this recent event and at $899 for the delta 2 and 220w panels as a package I figured it was time to pull the trigger.
