    The battery came well packaged, with the cable included. Once I got it in place and plugged it in, it worked perfectly with the EcoFlow Delta Pro 3. Being a refurbished battery the price was good compared to new. No visible damage, no marks noted - the battery looks new.

    Extra Battery is in great shape. The price is really good. The battery was at 30% and charged up with no problems. Battery and box are in great shape.

    I'm a firm believer in the eco flow system. However I was worried about the eBay refurbished items... Until now. I now have their newest smart generator and pro 3 and this was the refurbished extra battery. It is working perfect as all their products seem to do. Excellent seller and I truly trust their refurbished items. I absolutely will be purchasing from again!
