Overview

Product Overview

500mAh 3.7V lithium rechargeable battery for compact electronics, wearables, and embedded projects, delivering a small, lightweight power source in a 3.5 x 10 x 15mm form factor. This lithium battery cell is ideal for space-constrained builds such as Bluetooth devices, miniature sensors, data loggers, IoT nodes, and low-power robotics where rechargeable 3.7V power is needed. Use it with compatible charging and power-management circuits in Arduino, ESP32, Raspberry Pi Pico, and custom prototyping systems to provide portable energy storage for wireless modules, backup power, handheld designs, and rechargeable maker builds.

Questions & answers

Frequently asked questions

Yes, it can power Arduino, ESP32, Raspberry Pi Pico/RP2040, and custom embedded projects when used with a compatible charging, regulation, or power-management circuit. Do not connect it directly to boards that require a different input voltage.
It is a compact rechargeable cell for integration, not a standalone USB power bank. Use appropriate wiring or a connector, plus a lithium charger and power-management circuit suitable for a 3.7V cell before use.
It is a rechargeable lithium cell rated at 3.7V nominal and 500mAh capacity, in a 3.5 x 10 x 15mm form factor. Charging must be handled by a compatible lithium battery charging circuit.
Its small size suits compact electronics such as wearables, Bluetooth devices, miniature sensors, data loggers, IoT nodes, handheld prototypes, and low-power robotics where rechargeable portable energy storage is needed.
Full-size Raspberry Pi boards typically need regulated 5V input and may draw more current than a small lithium cell setup can safely provide. Use a proper boost regulator or power-management board instead of connecting this battery directly.
