Hey man.. Not sure if you are still looking, but I have 2 504w 2019 batteries for sale. Bought 2019 Levos for the wife and I and I have 700w batteries on back order.
My bike has 3 charges on it and Wife's just has 1 charge. Both obviously look like new. If you are interested, you can PM me here, but I am more active on Pinkbike and EMTB Forums and I have them listed for sale there too.
Located in North Idaho but Ill work with you on shipping.
