A slim, open-top 2×AA battery holder with a genuine JST PH connector. Two AA batteries in series provide approximately 3V — ideal for powering low-voltage electronics projects, Adafruit boards, and microcontrollers with JST PH battery inputs.
The JST PH connector polarity matches Adafruit's Li-Ion/LiPo batteries and 2-pin JST cables, so it plugs straight into compatible boards without rewiring. The genuine JST connector ensures a smooth, secure fit that won't catch or tear.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- JST PH
- A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- pH
- A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.
