601665 3.7V 680mAh LiPo Battery

Overview

The 601665 3.7V 680mAh Lithium Polymer Pouch Battery is a high-capacity, slender-profile rechargeable cell purpose-engineered for elongated device housings. Its unique 6.0 × 16 × 65mm geometry — just 16mm wide but 65mm long — makes it the natural fit for pen-body cameras, action cameras, GPS trackers, and stick-form wireless devices where conventional wider cells physically cannot fit. At 2.516Wh, it delivers meaningful runtime in a lightweight aluminum-laminate pouch package, with factory-installed PCM protection and ready stock available for immediate dispatch.

⚡ Key Specifications

✅ Product Highlights

1. The Slim-Long Form Factor — Built for Cameras & Pen-Body Devices Most LiPo cells in the 600–700mAh range measure 30–40mm wide, making them incompatible with tubular or stick-form enclosures. The 601665’s 16mm width and 65mm length mirrors the internal cavity geometry of pen cameras, body-worn recorders, and slim action cameras — enabling integration without housing redesign. If your product has a narrow elongated battery bay, this cell was made for it.

2. 680mAh / 2.516Wh — Substantial Runtime in a Lean Package Despite the narrow 16mm profile, the 65mm cell length allows for a 680mAh rated capacity — enough to power:

• A 1080p action camera for 60–90 minutes of continuous recording
• A GPS tracker for 48–72 hours of periodic transmit operation
• A voice recorder for 8–12 hours of active recording
• A Bluetooth device for 10–15 hours of standby/talk time

3. Factory-Installed PCM — Full Protection Standard Every cell ships with an integrated Protection Circuit Module:

• ✅ Over-charge cutoff at 4.20V — prevents cell swelling and thermal runaway
• ✅ Over-discharge shutdown at 3.0V — protects cycle life
• ✅ Over-current & short-circuit protection — safeguards downstream circuitry
• ✅ Low internal impedance for stable voltage delivery under load

4. Aluminum Laminate Pouch — Lightweight & Hermetically Sealed The silver aluminum-laminate soft pack enclosure provides:

• Superior weight-to-capacity ratio vs. steel-can Li-ion cells of equivalent capacity
• No electrolyte leakage risk — hermetically sealed pouch construction
• Flexible form tolerance — minor dimensional variation absorbed by the soft shell without housing stress

5. 500+ Cycle Longevity Rated for over 500 full charge-discharge cycles at 80% capacity retention. In a camera or tracker used daily, this translates to 18+ months of regular service life before capacity degrades below usable threshold.

6. Ready Stock + OEM / ODM Customization Standard 601665 680mAh cells are available ex-stock for immediate sampling and production. Custom variants — different connector, wire length, PCM rating, capacity adjustment, or label — deliverable within 7–15 business days.

🎯 Application Scenarios

• 📷 Action Cameras & Body Cameras — 65mm length matches stick-cam and body-worn housings; 680mAh delivers 60–90 min recording
• 🚗 Dash Cameras & DVRs — sustained low-drain recording with stable voltage delivery
• 🖊️ Pen Cameras & Covert Video Recorders — pen-diameter enclosures demand exactly the 16mm narrow width
• 📍 GPS Trackers & Asset Monitors — 680mAh sustains days of periodic GPS ping in low-power mode
• 🎙️ Digital Voice Recorders — long cell length fits pen and stick-form recorder bodies
• 🔦 Flashlights & Inspection Lights — tubular housings benefit from the 65mm form factor
• 🩺 Wearable Medical Monitors — stable discharge for ECG patches and ambulatory monitors
• 📡 Handheld IoT Terminals — adequate capacity for cellular/BLE field devices

⚠️ Designed for standard low-drain applications (max 1C / 680mA continuous discharge). Not recommended for high-current power applications. For high-rate camera flash or motor drive applications, please inquire about our dedicated high-C-rate series.

⚠️ Safety & Storage Guidelines

• Store at 40%–60% charge state; recharge every 3 months during long-term storage
• Keep in a cool, dry place — avoid direct sunlight, heat sources, and high humidity
• Charge only with a dedicated LiPo / Li-ion charger set to 4.20V CV/CC — never use NiMH chargers
• Do not puncture, crush, bend sharply, or expose to temperatures above 60°C
• If cell shows swelling, unusual heat, or deformation — discontinue use immediately and discharge safely
• UN38.3 certified — compliant with IATA / ICAO regulations for international air and sea shipment
