I used the battery maybe twice only, it has a valid warranty. Its current market price is 2500, and this is a picture from Mukab. It's usually not available. For sale to the highest bidder. Please do not undervalue the item. It has type C inputs, two three-pin outlets, and USB as well. The highest bid reached 1100. The price is 1300. And for the serious buyer, we won't disagree.
