I’m thinking 4x 18650 in series and this driver driving the leds 2s2p. Is there another way to individually address the leds?

I’m not sure if this is right but an LD2 driver for 4 batteries in series with whatever current output you wanted with the 4 leds in parallel.

Hmm… that could be a good option, I like led4power’s drivers.

This quad comes with resistors for connecting the points on the t-pad. Will that add more heat to the board? Other than making the connections what is their purpose?

I soldered the jumpers on the ones I had.
I thought they were zero Ohm resistors anyway so shouldn’t make any difference. They are there to determine if the leds run in parallel, series or a combination of both.

Ooh, thanks DNF :slight_smile:
