This battery holder connects three AAA batteries together in series, which produces between 3.6V and 4.5V (depending on the calls used), great for powering all kinds of projects.

As you would expect for smaller AAA batteries, the box is compact so will fit well in many enclosures or even a wearable project.

The 2-pin JST-PH connector is handy too - especially considering the output voltage is similar to what a LiPo battery would produce. Many microcontrollers come with these battery connectors and can accept the same voltage level this battery pack offers. Safe, zero-hassle portable power!

The holder accepts standard AAA batteries. When using 1.2V rechargeable NiMH batteries you'll see ~3.6V output, or use with 1.5V alkaline cells for ~4.5V output.

The polarity matches that of our 2-pin JST cable and Li-Ion/Poly batteries.


  • Box Dimensions: Approximately 62mm x 37mm x 15mm
