502020 3.7V 150mAh LiPo Battery

Product Description — 502020

502020 Pure Cobalt Rechargeable Lithium Polymer Battery | 3.7V 150mAh | Driving Recorder · Beauty Instrument · Digital Photo Frame

Overview

The 502020 Pure Cobalt Lithium Polymer Battery is a precision-grade, ultra-compact rechargeable cell engineered for electronics that demand consistent, clean power delivery in a minimal footprint. With a 3.7V nominal voltage and 150mAh capacity packed into a neat 5.0 × 20 × 20mm square body, this battery is uniquely optimized for dash cameras, facial beauty instruments, digital photo frames, and other compact consumer electronics where voltage stability and long-term reliability are non-negotiable.

The Pure Cobalt cathode chemistry sets this cell apart from standard LiPo alternatives — delivering a flatter discharge curve, superior charge retention, and a longer usable cycle life that translates directly into better real-world device performance and lower total cost of ownership.

Product Specifications

Key Features

• Pure Cobalt (LiCoO₂) Cathode Chemistry — The single most significant differentiator of this cell. Pure cobalt chemistry delivers a measurably flatter and more stable discharge voltage curve than NMC or standard mixed-oxide alternatives, ensuring that voltage-sensitive devices like beauty instruments and dash cam processors receive clean, consistent power from the first minute of use to the last
• Square 20 × 20mm Footprint — The symmetrical body geometry makes the 502020 exceptionally versatile for PCB-adjacent mounting in square or compact rectangular device housings, including digital photo frame internals, handheld beauty devices, and flush-mounted dash cam modules
• Superior Charge Retention — Pure cobalt chemistry exhibits a lower self-discharge rate than standard LiPo formulations, meaning photo frames and beauty instruments left unused between sessions retain significantly more charge — ready to perform without needing a top-up every time
• High Voltage Stability for Sensitive Electronics — Beauty instruments such as RF skin tighteners, EMS devices, and LED therapy tools are particularly sensitive to power fluctuation. The 502020’s flat discharge profile ensures consistent treatment intensity throughout the battery’s operational range, protecting both device performance and user experience
• Dash Cam Optimized Endurance — Low internal resistance and stable discharge behavior support the continuous-write demands of driving recorder modules, preventing recording interruptions or file corruption caused by voltage sag under sustained load
• Compact 5.0mm Slim Profile — The 5.0mm thickness fits within the tightest slim-body device enclosures, enabling sleek industrial design without compromising on energy capacity
• Built-In Protection Circuit (PCM) — Comprehensive overcharge, over-discharge, over-current, and short-circuit protection ensures safe operation across all three target application categories — from always-on recorders to intermittently used beauty tools
• 500+ Cycle Life — Extended service lifespan minimizes end-user replacement requirements and reduces warranty return exposure for device manufacturers and OEM partners
• Lightweight at ~3.5g — Negligible weight contribution to handheld beauty instruments and compact portable devices, preserving ergonomics and portability
• In-Stock Availability — No lead time delays; warehoused and available for immediate dispatch on standard and bulk orders

Why Pure Cobalt Chemistry Matters

💡 For beauty instruments and driving recorders where stable voltage directly affects output quality and recording reliability, Pure Cobalt chemistry is the technically superior choice over commodity LiPo alternatives.

Application Deep Dive

Driving Recorders / Dash Cams Continuous video recording places a sustained, moderate load on the battery. The 502020’s low internal resistance and stable discharge profile prevent the voltage sag that causes frame drops, file write errors, or unexpected recorder shutdowns — keeping footage intact from ignition-on to ignition-off.

Beauty Instruments RF, EMS, and LED beauty devices are among the most voltage-sensitive consumer electronics. Fluctuating supply voltage directly translates to inconsistent treatment intensity, affecting both efficacy and user perception of device quality. The Pure Cobalt flat-curve discharge guarantees that treatment energy output remains consistent from a full charge through to the low-battery threshold.

Digital Photo Frames Standby-heavy devices like digital photo frames benefit enormously from the Pure Cobalt cell’s low self-discharge rate — maintaining display readiness over days or weeks between active use sessions without requiring constant recharging.

Compatibility

The 502020 is designed as a compatible replacement and OEM supply battery for driving recorders, beauty instruments, digital photo frames, and compact electronics utilizing a 3.7V lithium polymer cell in the 5.0 × 20 × 20mm form factor.

⚠️ Please confirm your device’s battery cavity dimensions (5.0 × 20 × 20mm) and operating voltage (3.7V) before purchasing. Custom connector types, wire lengths, and lead polarity configurations are available on request.
