Educational Applications	This battery can be used to teach students about: Lithium-ion battery technology Rechargeable energy storage Battery voltage Battery capacity Energy consumption Charging and discharging Battery-powered robotics Power management Series and parallel battery configurations
Multi-Cell Applications	Multiple 18650 cells can be combined in series or parallel for appropriately designed battery packs. For example, connecting cells in series increases the overall voltage. However, multi-cell Li-ion packs require proper cell matching, protection/BMS circuitry, and a compatible charging system. Do not connect individual cells together without understanding the required battery-pack design and protection requirements.
Charging & Compatibility	This is a 3.7V nominal Li-ion cell with a stated 4.2V full-charge voltage. Use only a compatible Li-ion charger or charging module designed for the appropriate cell configuration. A generic power supply should not be connected directly to the battery for charging. The battery should also not be connected directly to an electronic device unless the device's voltage and current requirements are compatible with the battery and appropriate regulation/protection is provided.
What's Included	1 × 18650 Li-ion 3000mAh Rechargeable Battery
Important Notes	This is a hobby-grade lithium-ion battery. Actual battery performance and runtime depend on the connected device and operating conditions. Do not short-circuit the battery. Do not puncture, crush, disassemble, or physically damage the cell. Do not expose the battery to excessive heat or fire. Do not use a damaged, swollen, leaking, or otherwise compromised battery. Use an appropriate Li-ion charging system. Keep away from children and use appropriate supervision in school/lab environments. Store and handle lithium-ion batteries responsibly.
Why Choose It?	The 18650 Li-ion 3000mAh Rechargeable Battery offers a practical rechargeable power source for students, educators, makers, and hobbyists working on robotics and electronics projects. Its compact 18650 form factor, 3.7V nominal voltage, and 3000mAh stated capacity make it suitable for exploring real-world rechargeable power systems and portable electronics.
Product Summary	A 3.7V 3000mAh rechargeable 18650 Li-ion battery for hobby electronics, robotics, STEM education, IoT prototypes, and DIY projects. Requires a compatible Li-ion charging and power-management system.
