Hello,
I am a general amateur in electronics.
I have a bluetooth speaker i made myself but i have an issue, it is powered with two 18650 cells in parallel (parallel for charging via a 1s micro usb charger) they go through a eBay boost converter, thus going from 3.5-4.2 (1s LiOn voltage) to the minimum required voltage for the amplifier, around 7.5 volts. The problem is that the converter only delivers about 700mah max. With heavy bass the converter doesn't match the current requirements and it pops loudly. So i need a a boost converter that can boost the cell voltage and deliver 2-3 amps successfully.
Please let me know. Thanks, Nick~
