## Description

This compact battery holder connects 3× AA batteries in series, providing 3.3–4.5V output — a similar range to lithium-ion/polymer batteries. It features a built-in on/off switch and a genuine JST-PH 2-pin connector with a 6" cable, making it a convenient drop-in power source for 3.3V projects with JST battery connectors. The polarity matches standard 2-pin JST cables and Li-Ion/Poly batteries, so it can be used as an alternative non-rechargeable power source for boards designed for LiPo batteries. Key Features 3× AA Series Configuration – 3.3–4.5V output range Genuine JST-PH 2-Pin Connector – Polarity-matched, smooth insertion and removal Built-In On/Off Switch – Convenient power control 6" Cable Length – Flexible placement options Voltage Output Alkaline – 4.5V (new) to 3.3V (end of life), nominal ~4.5V NiMH Rechargeable – 3.7V (charged) to 2.7V (end of life), nominal ~3.6V Ideal For 3.3V microcontroller projects with JST battery connectors Portable electronics and wearables Alternative to LiPo batteries where rechargeability isn't needed Educational and prototyping projects Package Contents 1× 3×AA battery holder with on/off switch and JST-PH 2-pin connector Warning: Do not connect this battery holder to Li-Ion/Poly charger boards — AA batteries are not rechargeable via these chargers and attempting to do so is dangerous. Note: Batteries not included. Fits any standard AA battery.
