The 18650 Li-ion Rechargeable Battery (3.7V, 2500mAh) is a high-output cell ideal for powering DIY hd老熟女bbn, robotics, IoT prototypes, flashlights, and portable power projects. It delivers stable energy, good runtime, and is widely used in Ghana for STEM kits and maker builds.

Key Benefits

• 2500mAh (2.5Ah) capacity for longer runtime

• 3.7V nominal Li-ion output (charges up to 4.2V when full)

• Works with standard 18650 holders, cases, and battery packs

• Suitable for single-cell builds or multi-cell packs (with the correct BMS)

Typical Uses

• DIY power banks & portable backup packs (with power bank/BMS module)

• Robotics projects (motors + drivers)

• IoT builds (ESP32/Arduino with regulator)

• High-power LED/flashlight projects

Charging & Compatibility
Use only a Li-ion charger such as a TP4056 module (for 1 cell) or a smart 18650 charger.
For 5V projects, use a boost converter (3.7V → 5V). For 3.3V projects, use a regulator or bulk converter (3.7V → 3.3V).

Safety Note (Important)
Do not short-circuit, puncture, overheat, or overcharge. For battery packs (2S/3S/4S), always use a matching BMS.

Package Includes

• 1 × 18650 Li-ion Battery (3.7V, 2500mAh)
