(on core2duo you can’t eihter) you can check internet for comparison of CPUs performance. > [@murm](#): > > is there any way to just buy from amazon compatible batteries with larger energy density? no, but there non-official board that allow you to replace 18650x2 with lion square battery, it will have more capacity if you are willing to do it. > [@murm](#): > > and any of you have any experience on how long their devices last depending on the battery? with 2x18650 you should have ~5 hours. _(±2h)_ > [@murm](#): > > boards like he radix that I think have a heavier spec? did you mean radxa? it works, but no audio and wifi so you need to use usb dongle. > [@Radxa CM5 - Will it work?](https://forum.clockworkpi.com/t/radxa-cm5-will-it-work/19329): > > Would this board work in our Uconsoles? --- _[View the full topic](https://forum.clockworkpi.com/t/a-few-questions-about-cpu-gpu-battery-and-so-on/20618)._
