{"title":"2 x AA Battery Holder with On/Off Switch  JST PH Connector","handle":"2-x-aa-battery-holder-with-on-off-switch-jst-ph-connector","url":"/products/2-x-aa-battery-holder-with-on-off-switch-jst-ph-connector","description":"A slim 2×AA battery holder with a built-in on/off switch and genuine JST PH connector. Two AA batteries in series provide approximately 3V — ideal for powering low-voltage electronics projects, microcontrollers, and portable builds without needing to disconnect the battery to turn off power.\n\nThe JST PH connector polarity matches Adafruit's Li-Ion/LiPo batteries and 2-pin JST cables, so it plugs straight into boards with JST PH battery inputs. This is also a great upgrade for micro:bit projects — the on/off switch means you don't have to unplug the connector to power down, and AA batteries last significantly longer than the AAA cells in standard micro:bit battery packs.\n\nKey Features\n\n\nOn/Off Switch – Conveniently control power without disconnecting\n\nGenuine JST PH Connector – Correct polarity, smooth fit in JST sockets\n\nSlim Form Factor – Compact holder for portable and wearable projects\n\nStandard AA Batteries – Widely available, long-lasting power\n\n\nSpecifications\n\n\nBattery Type: AA (not included)\n\nCell Count: 2 (series)\n\nOutput Voltage: ~3V nominal (alkaline), ~2.4V nominal (NiMH rechargeable)\n\nConnector: JST PH 2-pin\n\n\nIdeal For\n\nmicro:bit projects (replaces AAA battery pack with longer-lasting AAs)\nAdafruit boards with JST PH battery inputs\nPortable electronics and wearable builds\nSTEM education and classroom projects\n\n\nPackage Contents\n\n1× 2×AA Battery Holder with On/Off Switch and JST PH Connector\n\n\n\nNote: AA batteries are not included.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5268,"title":"Default Title","sku":"AF-4193","price":4.56,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":105,"option1":"Default Title"}]}
