18650 DIY Power Bank Bluetooth Speaker from Aliexpress

This is me assembling and testing out a neat DIY Bluetooth speaker from Aliexpress using 18650 batteries I recovered from an old EUC battery. It uses 8 batteries in parallel so the capacity can be as little or as much as you want as it depends on the cells quality. At the time of purchase, speaker was 28cdn and took about 2 weeks to arrive. Assembly is very easy as it uses spring loaded battery holders which makes install and servicing very easy. Speaker output is also quite good though i don't know the specs of the speaker. Don't expect this to be better than a Sony or JBL speaker, but for the price and added power bank functionality, it can't be beat. Check it out here.
