Dewalt powerstack 5ah bms

Looking for a source to replace the bms on a dewalt powerstack 5ah ( pouchcell)

Bms is covered in hot glue so board level repair is difficult but not impossible

Friend of mine fried his and I was able to remove the glue . He fried the mosfets and while I can replace them I would rather buy a brand new bms and replace it .

If anyone has a source for dcbp520 bms please send me a link
