Application for lipo battery 3.7 v 350mah 801730
Its mechanical robustness (verified by vibration and 1m fall tests) ensures the power supply remains secure even in harsh logistics or industrial tracking scenarios.
It allows for longer talk time and standby periods in premium headsets without increasing the physical footprint, while the stable 3.7V discharge ensures consistent audio quality.
Low self-discharge rates (Residual Capacity >90% after 30 days) make it ideal for remote sensors that may spend periods in low-power standby mode between data transmissions.
Lightweight at approx. 11g, it contributes to the portability of patient monitoring devices, pulse oximeters, and handheld diagnostic tools.
Standard CC (1C) and Quick CC (1.5C) charging options allow for fast turnaround when the device needs a recharge, enhancing user convenience.
The 500+ cycle life is critical for wearables that require daily charging, ensuring the device remains functional for several years of active use.
The high energy-to-weight ratio allows for extended flight times in micro-drones compared to traditional battery formats.
The 51021-002 connector and 1007AWG#28 wires ensure a secure, plug-and-play connection for easy manufacturing and field replacement.
