12-24V will be fine, but the heating power will drop to 50% at 18V and 25% at 12V.

Probably the battery just died. Just fancy and not really needed. You could fit a 1-farad super capacitor which charges from 3.3V through a diode, use low leakage type, should hold for weeks.

As long as the LDO doesn't give problems, don't worry and  just use it as-is, if the station starts to reboot randomly then it's probably the regulador overheating.
There're several solutions in GitHub.

So if the battery is stable at 18v, say i use a 12ah milwaukee battery, and i calibrate the temp for the tip im using, aslong as the voltage stays pretty stable i should be fine to reach higher temps? and the battery isnt needed to save the tip profiles is it? thanks

DavidAlfa:
No, the battery only stores very commonly changed settings (temperature, current tip etc), disabling the battery will simply use internal flash, no difference really.

Hi! I'm trying to dump the stock firmware on my Ksger T12 before flashing the custom firmware, it's 3.10 with 3.1S software and I keep getting the "could not determine read protection status" error with Pico pwner. Any idea how to fix this?
I'm getting the USART pin from the oled, BOOT0 from C5 and NRST from C4

DavidAlfa:
Make sure you're using openocd 0.12 or newer.
Connect the stlink (rst, swc, swd , gnd), power the board and check what openocd says:

--- Code: ---openocd -f interface/stlink.cfg -f target/stm32f1x.cfg -c init -c "reset halt" -c "stm32f1x options_read 0" -c "exit"
--- End code ---

In my case I also have to run "sudo chmod 777 /dev/ttyACM0" everytime I plug the stlink or it won't work.

I run picopwner in one window, when asked to connect the stlink I do so and run that cmd in a separate shell.
