3.7V 1200mAh Lithium Polymer Li-Po Rechargeable Battery is a high-energy-density single-cell (1S, 3.7V nominal / 4.2V full) rechargeable LiPo pouch battery designed for mini quadcopters, handheld instruments, portable Bluetooth speakers, and solar-powered IoT devices. Offering 1200mAh (4.44Wh) capacity in a slim, lightweight flat-pack profile, it delivers substantially longer runtime than 300mAh/500mAh cells while weighing a fraction of a lead-acid battery.
Key Features:
- High 1200mAh (4.44Wh) Capacity: Provides extended operating time for Wi-Fi/cellular IoT nodes, handheld displays, and mini RC aircraft.
- Slim Prismatic Pouch Profile: Flat rectangular form factor mounts flush behind LCD screens, inside handheld project boxes, or under mini drone frames.
- Compatible with 1A TP4056 Chargers: Unlike tiny <500mAh cells, a 1200mAh cell safely accepts the standard 1.0A (~0.83C) charge current of off-the-shelf TP4056 charger modules without modification.
- Low Self-Discharge & No Memory Effect: Can be topped up at any state of charge and retains >85% charge over months of storage.
- Pre-Attached Wire Leads: Color-coded red (+) and black (-) flexible insulated wire leads simplify integration.
