Ostation B AA Rechargeable Battery

The Ostation B 1.5V rechargeable Li-ion battery is the world’s first AA-sized rechargeable battery to integrate a BMS. Each cell has an embedded chip for real-time temperature monitoring and health management, seamlessly working with the Ostation 2 Series charger to optimize current for safety and efficiency. At the same time, per-cell ID and health data are accessible, ensuring true digital management.
A proprietary technology ensures a constant 1.5V output, allowing safe mixed use without voltage spikes. Dual-layer enclosure prevents leakage and boosts durability, while both the positive cap and pogo pin are made of pure copper with gold plating to minimize resistance and support up to 3A discharge for demanding devices. The Ostation B fully replaces standard 1.5V alkaline cells, fitting all devices designed for 1.5V batteries. Supporting up to 1,000 cycles and featuring a built-in battery management system, it encourages wider use of rechargeable batteries and supports environmental sustainability.
