Can we fix this Schumacher Li-po Jump Starter?

In this video we look inside this Schumacher Jump pack and see why it is not charging. This video is much longer than I intended, but I wanted to show as much as possible about the Lithium cells and how they can lose capacity and not function as intended. In the end I had to wait a couple weeks on a new battery to truly get this booster pack back in tip top shape. I believe this booster pack is handy enough to justify $20 to save if only for the device power bank charging capabilities alone. Hope you find this video helpful and thanks for Watching!
