I am planning to build lsr with lpc-826 diode with lm317 driver
what battery(batteries) I need to power it? (570mA)

Need 7 what? Also, if this is like many of the other red diodes, direct driving with 2x1.5V batteries works as long as your diode is heatsinked. I have done his with 635, and 660 diodes and never had an issue. Cheers.

lol i read it too quickly. i thought he asked for the voltage.

with lm317 use 2 3.7v lithium batteries.

2 cr123s in series should work and fit any 18650 hosts like the hotlights

2x CR123 is kind of a pain to fit in hotlights.

Grab 2x 10440s. Then just solder a piece of wire across the third 10440 battery slot. Two of those batteries will give you enough voltage and enough current to power an LM317 based driver for a red diode.

Simple, more than capable, and leaves you lots of room in the pill to build the driver without needing to modify the hotlight.

Do you plan on using the driver in a hotlight host? Hotlights usually don't have a clicky switch on the tail. In a hotlight you connect the (-) from your driver to a bare metal part of the host housing. The (+) is coming from the front metal tab of the switch. Somebody here on the forum made a nice guide about the hotlights with really nice pictures.
