Capable of powering from 1 to 5 LEDs though the more LEDs you have the quicker the battery will drain and the less bright the LEDs will be.

How to connect the battery to your LEDs

It is very easy. Just connect the red wire to the red wire and black wire to black wire.
The best way to do this is to solder the wires together and cover the joins with heat shrink tubing but if you're not a dab hand with a soldering iron just twist the wires together and protect the join with either electrical tape or heat shrink tubing. 2 x 1 inch pieces of 2.4mm heat shrink tubing will be supplied with your battery holder.



For a more reliable connection for larger numbers of LEDs we recommend using a connector block. Simply twist the wires together as before and place under the screw. Tighten the screw to secure and attach the battery wires opposite the corresponding LED wires. A connector block will also be supplied with your battery holder.
