I have modified it to work with a li-ion battery with mt3608 step-up converter and tp4056 usb li-ion charger. Also, the battery itself has a protection module. Now, it can also output on 9v dc, so I can use it to power other devices. Seems to work without problem. I have not removed R30 and did not use the switch, instead, I have connected a switch directly to the output of the battery.

  • Samuel I've just ordered the parts to do the same with mine. Is yours still running ok?

  • Doctorzorro May I ask what battery you used? Was the protection circuit already in it or is that a separate module also?
