hi guys,
can anyone suggest me a bluetooth speaker with 18650 battery option and song selection using mobile app so we change song SD card of speaker
still now polaris V8 have 18650 option and SD card, but no sd card song selection.
Offtopic:
atleast with replacable battery, as bluetooth speakers die only due to dead battery after 1 or 2 year.

because 18650 have high capacity, example : panasonic 18650 batteries have 3400 mAH, that battery life is more than 2 years,
i am addicted to 18650 
i bought one LED flash light from aliexpress, that use only one 18650 battery, i not seen that much brightness before (2000 lumens advertised, but bright enough to make day light thing in room), so 18650 is best and future proof, easy to replace.
