This 3V battery holder will power all of our 3V LEDs. Uses 1 coin cell battery to power 1-10 chip size LEDs (available here). If your project requires more LEDs, you may like the larger AA battery holder and switch unit, which powers up to 30 chip size LEDs.
This unit works well when your project is very small and/or portable.
10 chip-size LEDs will run for about 12 hours. 3 chip-size LEDs will run on a single battery for about 40 hours. One chip draws approximately 20 milliamps.
Connects to LEDs using the included shrink tubes. No soldering is needed.
- on/off switch
- 2032 coin cell battery
- shrink tubes for covering the connections
Connecting the LEDs
- Twist the red wire from the switch to all of the red wires on your LEDs; use shrink tube or electrical tape to protect the connection.
- Twist the black wire from the switch to all of the green wires on your LEDs; cover the connection with shrink tube or electrical tape.
- Insert the coin cell battery (included) into the holder.
- Turn on the switch and enjoy!
The white switch allows you to easily turn off the lights without disconnecting the battery. The battery can run up to 10 3V LED lights for about 12 hours. 3 lights will light for about 40 hours. The battery is changeable.
This set will work with ALL of the LEDs from True2Scale.
You may wish to use wired connectors to extend the length of the wires from the battery holder and switch unit to the LEDs.
Some countries do not allow packages containing lithium batteries. If your order is to be shipped outside of the United States, it is up to you to find out if your country will allow packages containing lithium batteries. If your country does not allow these items, we can remove the battery from your package before shipping. Please contact us or write a note during the checkout process.
Dimensions of the battery holder and wires
The wires on the battery holder are 4" long. You may wish to use wired connectors to extend the length of the wires from the battery holder and switch unit to the LEDs.
The battery holder is 15/16" (24mm) at the widest area. Length: 3/4" (19mm) Depth 7/32" (6mm)
