Customer Reviews for EcoFlow - DELTA Pro 3600Wh Extra Battery

Very easy set up and charging. The wheels are sturdy and the wireless interface worked very well. Hooked up to the delta pro and smart generator also seemless. Had to use it for a power outage for 12 hours and worked running TV, internet and refrigerator and extra freezer. No issues at all. Great product
I would recommend this to a friend!

Great products, but limits on installation options

Coupled this with my Delta pro main unit. All is working well, but really nee more flexibility on the connection cables. The basic ones are just long enough if the units are directly side by side. This limits where one can place the equipment (eg stacking or wanting to leave more space between units in poorly ventilated ares to improve air flow.

Really pleased with the two extra batteries I bought for the two Ecoflow Delta Pros I bought. It's best to learn a little about how these batteries work so they work most efficiently and last the longest. Best way to do that is by joining one the Facebook Delta Group. Lots of knowledgeable and helpful members. The battery is heavy like the Delta Pro it supports because it has the same capacity, 3.6K Watt hours. The cable that attaches the battery to the Delta Pro is short so consider that when you are planning where to put it. The good thing is that two batteries can be attached to the Delta Pro, giving a total of 10.8K Watt hours.

It was bought by mistake, but it is working well. It gives my Delta Pro power station a nice reserve power. I wish that I could charge it independently like a Bluetti. I like the portability of wheels and handle to help move it around.

I’ve had my delta Pro smart extra battery about a month now. After using my Delta pro alone all summer I got concerned it would not have enough power to get me thru the night in the winter months on our off grid property. In summer with more daylight hours I would be down to mid 40’s percent battery life in the morning and that’s without using the propane furnace in my RV. After connecting the eco pro smart extra battery and using the furnace (since it’s getting colder at night in Kate September) I now have about 80% average battery life left in the morning. I charge using 6 240 watt solar panels which charge both units in a matter of a few hours. I have a firman remote start generator in case I have No solar during the day and it charges both units in a few hours as well. I’m looking forward to purchasing the EcoFlo smart generator next year and I will be set.

great expansion to the delta pro. my biggest gripe is that the cables stick out almost an extra foot making it a little hard to build into a small footprint. I wish there were right angle cables or adapters available.

My Only Delta Series Issue
on August 4, 2024
Posted by: D. J. W.
from Northeast PA

I've purchased 20 different Delta series batteries and I give EcoFlow an A+ in every catagory except one. This regards my two Pro Batteries and two Pro Extra Batteries. The Extra Battery Cable (EBC) is of limited usefulness due to its short length. I want to mount the Pros and Extras on a two-shelf (top and bottom) heavy-duty utility cart (with four caster wheels). The current EBC will not allow this configuration because it is too short; also, for a proper fit, one connector should be rotated 180-degrees from the other. With the proper EBC, I'd have one Pro on the top shelf and two Extras on the bottom shelf of each utility cart, i.e., two carts with two identical set-ups for use with the 240V double-voltage Hub accessory. This would require me to purchase two more Extra Batteries. However, my entire design fails for the need of a little longer EBC -- a connecting cable! Customers have requested a longer EBC for at least two years and, still, EcoFlow has not responded to them in any way. Why? It is only a connecting cable! Will EcoFlow ever address this problem? I don't want to order two more Extra Batteries if EcoFlow has made a decision to never address this EBC shortcoming (so to speak).
