I purchased a used JBL Flip Bluetooth speaker with a dead battery for $20. I know there are Bluetooth speakers out there that are cheap but probably don't sound that great. I took a chance this used JBL speaker because I have already heard the sound quality before the purchase. I bought a new lithium replacement battery for $15. So overall, I have spent $35 on the whole thing. I think the outcome would still be better than buying a cheaper off brand Bluetooth speaker with inferior sound. So this video, I will show you how to replace the old battery of JBL Flip. Enjoy
