<p dir=&quot;ltr&quot; style=&quot;margin-top:0; margin-bottom:0;&quot;>Hello, Im am selling 1 used Eco delta pro extra battery, about 8 months old. I have upgraded to the Delta pro ultra and I dont have no use for these since it wont work with the ultra. They are in very good shape with very miner scuff marks from use. They all have been updated with the latest firmware. I would like to sell them one at a time to anyone interested since it is for one pictured. I will have more auctions posted for them, same descriptions with their photos to go along with them. I do have a 4th one that may go on ebay, still have not decided if I want to part with it just yet since it is connected and being used with a delta pro. What you see is what you will recieve plus the original box.&nbsp; Thank you for looking</p>
