I have not really paid attention, I have seen people do things like this but pretty sure they were using custom firmware that used the internal voltage reading and used the voltage resistor pads for the aux LED’s.
I forgot if I changed the default mode group to include turbo in the main mode groups or not come to think of it. Seems like I did though, if so then the brightest mode is already turbo. I can’t remember if he wanted me to do that or not, I was worried about the temps with a titanium light + turbo.
Regardless you can enter the menu and then pick whatever mode group you want and/or re-enable the reverse modes so that you can access turbo with a reverse click from moon.
Do TA drivers work with 4S batteries and leds? I have soldered a driver that only gives a short blink when connecting 4S batteries to 4S leds and lets the leds light up if I connect 3S to 4S.
If you use one of the LDO drivers and the correct components for 4S voltage, then yes it can work with 4S. The GT70 is a TA driver running at 4S voltage for example.
