*HELP PLEASE* Lumintop GT Nano battery pack mod

Hey everyone,

I want to make a battery pack for a luminto gt nano.
I want to do this so i can mount the flashlight on a pair of glasses for my partner to use in the dental clinic when she works on teeth.
My idea is to basically strip the lumintop gt nano of its battery and end cap, 3d print a mount and attach to glasses.
Then run wires to the flashlight to connect it to a battery pack in the pocket.

WHERE I NEED YOUR HELP
How can I make a battery pack from 18650’s or some larger capacity battery to connect to the flashlight without drawing a huge amount of current and frying the light?
She won’t need the light on turbo ever and most likely the light will not be used past 60% brightness (I’m guessing).

Any suggestion on how to do this would be greatly appreciated.

Cheers

GT nano will have spill. Do what I recommended here instead https://budgetlightforum.com/node/77457

Hey Sunny, i had a good read through, but i think i’d like to try with the GT nano.
I am not worried about spill as I can design and print a surrounding to focus the beam and also add a filter.
If you could provide a little help understanding the driver that may help me understand what to do.

From what i am aware, the driver in the GT nano will regulate the current for the normal batteries it takes, however when adding 18650’s would it still regulate it on the normal modes?
I know that when on turbo it goes unregulated and would definitely burn the LED, but could i add in resistors or some other limiter to fix this problem in case turbo was accidentally turned on.

Ideally i’d like to hook up the 18650s with something to limit the current in a case and just connect into the back of the GT nano with wiring.
