JBL Boombox - Full Teardown

This is actually a reverse teardown. I put this bluetooth speaker back together. That's more important than to see how it is taken apart.
This is taking almost 50 minutes, because if you want to change the battery, you have to take it all the way.
Overall this is a well built speaker.
The battery label spells the following:
Great Power Energy&Technology Co.,LTD
Model No. GSP0931134 01
Rating: 7.4V 10000mAh
74.0 Wh Lithium Polymer
Made in China
I did measure the dimensions of the battery with
150 length x 70 width x 23 mm thickness
Not sure if it is possible to squeeze in a bunch of Li-Ion batteries.
That would be a more difficult modification.
I couldn't find many teardown videos for this on YouTube. Make sure you watch this video before you attempt to open your own Boombox.
