A few things to confirm before publishing: the maximum continuous discharge current, BMS protections, dimensions, weight, and connector types. Those are the specs buyers ask about most, and I couldn't verify them from the photo. Also, at over 100Wh, this pack is classified as dangerous goods for shipping and can't go on passenger aircraft, so check your marketplace's rules for battery listings.
