WarHawk-AVG, we’re talking about Nanjg 110, not 105C

Right right

I goofed…sorry (and deleted my old post)

Modifying a Nanjg 110 boost driver for higher output

I got two of these Nanjg 110 boost circuits from Intl-Outdoor. Out of the package they’re pretty hot, delivering 1.1+ amps from 2AA. They draw over 2 amps from 2AA NiMH (which were ~2.15V under that load). I want to try and mod it for higher output and possibly better efficiency. Correct me if I’m wrong: I can swap out R1 for a lower value, or simply remove it altogether if I wanted to boost output? R1 and R2 are located at about 9 o’clock in the picture. [image]

Per the link above…adding a 2nd resistor would parallel the resistances reducing it w/o having to remove the original
