Battery

Batteries are the power source for portable and standalone electronics projects, supplying the voltage and current required to run microcontrollers, sensors, motors, and wireless modules without a tethered supply. Choosing the right battery involves balancing capacity, voltage, discharge rate, and physical size.

This collection covers a broad range of battery chemistries and form factors: LiPo packs for RC and drones, 18650 Li-ion cells for high-capacity portable builds, NiMH AA and AAA rechargeables for general use, CR2032 and CR2016 coin cells for low-power wearables and sensors, and standard alkaline AA and AAA cells.

Batteries in this range are used to power Arduino and ESP32 projects, micro:bit and Raspberry Pi builds, RC vehicles and drones, portable Bluetooth speakers, wearable electronics, IoT sensor nodes, and STEM education kits.
