I’m trying to repair a Chargeasap Flash 2.0 battery pack I received in non working order. The pack says it charges to 100% but won’t turn on and resets to 0%. I have removed labels from top and bottom and removed 6 screws from bottom plastic end but can’t seem to get battery assembly to slide out of metal case. Anybody have an idea how to get battery module out of case?

I finally figured out that the whole module slides out the end with the charge ports. I think there is something wrong with one of the boards. I’m just going to salvage batteries.
