Mods, please move this if it is in the wrong sub-forum. Seeking some advice and expertise. I bought a wireless Bluetooth adapter for my Bose QC15 headphones. It works pretty good with the exception of the battery life. Actually pretty disappointed in it. I get at most 2 hours instead of the 8-10 advertised. I’m hoping I can upgrade the battery even if I have to have it externally mounted. I have basic knowledge in soldering but not circuitry. If I bust it open and remove the battery and replace with wires leading to a battery carrier to hold a larger battery, will it work?? I have the following cells lying around; 300maH li-Po with PCM, 10440, 14500 protected, 18650’s protected/unprotected. I do like the idea of using the Li-ions as I can charge then separately and faster. Any ideas would be appreciated.
i bought it from BG. it will be the first thing that pops up if searching for QC15 bluetooth, if pictures help.
