Tell us about yourself!
Sorry if i did not make this clear. YOU NEED A PROTECTION CIRCUIT in extreme cases the battery can catch fire or explode
you need to have a protection circuit but if you get a 18650 battery and the micro usb charging port then yes
Short answer yes. It will power and work but when you try to change is it can over charge and ruin the battery or as you use it the battery will be over discharged so if you want to just test it for a short period of time then yes but if you want to use it for more than about 10 hours(assuming the battery is fully charged) no
Looks Great but did you use kerfing to bend the wood in the triangle like shape around the sides of the enclosure or some other method.
How did you make the holes of the radiator and speaker cutouts?
