Main advantages:
Compact size and lightweight:
High nominal voltage: 3.7V operating voltage, compatible with most low-power electronic circuits, no additional boost required.
High energy density: Ternary material system enables energy density of over 200Wh/kg.
Good cycle life: Supports approximately 300 charge-discharge cycles.
Good safety: Low risk of polymer electrolyte leakage; with a protection board, overcharge, over-discharge, and short-circuit protection are provided. Stable discharge performance: Low internal resistance, supports standard/maximum discharge current of 0.3A–0.6A, suitable for low to medium rate applications.
Main Applications:
Bluetooth headsets and TWS earphones
Smart wearable devices: such as smart bracelets, smart rings, health monitors
Miniature IoT devices: such as GPS trackers, shared bicycle lock modules, asset tags
Portable audio devices: small Bluetooth speakers, voice recorders
Medical electronic devices: such as thermometers, blood glucose meters, portable diagnostic instruments
