Need help designing 18650 battery pack. Answered
Hey guys, I'm trying to transform my JBL iPod deck which uses 13v 2.5Amps into a wireless bluetooth speaker for a better use. I have a couple of 18650s which has a capacity of 2500mah so i tried to connect 6 batteries in series and got 12.8volts but the issue is the battery capacity doesn't increases. Also some of the battery are 2.3v and 2.89v when fully discharged and has voltage of 3.6v as usual. So my doubt is can i connect 3x2.3v + 2x2.89v battery in series and 3x2.3v and 2x2.89v battery in parallel with the series ones to make it achieve more battery capacity?? If not how do i make a battery pack for 12v with better performance. The battery i have is Panasonic CGR18650C.
