The BAKTH-564261-1S1P 3.7V 1650mAh Lithium Polymer (Li-po) Battery is a compact, high-performance power solution tailored for small-scale portable electronics. Engineered with lithium polymer technology’s inherent advantages—flexible form, slim profile, and stable energy output—this battery combines model-specific design (encoded in “BAKTH-564261”) with reliable performance, making it ideal for wearables, IoT devices, and consumer gadgets where space and weight are critical constraints.
Core Specifications & Stable Power Delivery: At its core, the battery features a 1S1P configuration (1 cell in series, 1 cell in parallel), delivering a nominal 3.7V voltage—perfectly matching the power requirements of most miniaturized electronics (with a safe operating range of 4.2V fully charged to 3.0V discharged). Its 1650mAh capacity translates to practical, long-lasting runtime: it powers true wireless earbuds for 5–7 hours of continuous playback, smart fitness trackers for 4–6 days of daily use (including heart rate monitoring), or small Bluetooth beacons for up to 2 weeks of intermittent operation—eliminating frequent recharging hassles.
Model-Specific Slim & Flexible Design: The “564261” designation in the model refers to the battery’s compact dimensions (approximately 5.8*44*63 mm), a slim profile that fits seamlessly into ultra-thin device enclosures. Unlike rigid cylindrical batteries, its Li-po construction offers moderate flexibility, allowing it to conform to curved or irregular shapes—such as the contoured casings of smartwatches, medical patches, or mini IoT sensors. This design versatility makes it a top choice for OEMs and DIY enthusiasts building space-constrained devices where every millimeter matters.
Robust Safety & Long-Term Durability: Safety is integrated into every layer: the battery uses a high-quality aluminum-plastic film outer casing to prevent leakage and enhance thermal stability, while a built-in protection circuit guards against overcharging, over-discharging, short circuits, and overcurrent. These safeguards reduce risks of overheating or swelling, even in enclosed device housings. Additionally, it boasts a long cycle life of over 300 charge-discharge cycles (retaining ≥80% of initial capacity), outperforming lower-grade Li-po batteries and ensuring consistent performance over time.
Practical Performance & Versatile Use: With a low self-discharge rate (<4% per month), the battery retains charge during storage—ideal for backup devices like emergency sensors or infrequently used gadgets (e.g., portable thermometers). It operates efficiently across a wide temperature range (-20°C to 60°C), making it suitable for both indoor (e.g., office wearables) and outdoor (e.g., camping Bluetooth speakers) applications. Compatible with standard 3.7V Li-po chargers, it reaches 80% capacity in just 1.2 hours, minimizing downtime.
Ideal Application Scenarios: This battery excels in powering:
Wearable Tech: Smart bands, fitness trackers, and mini smartwatches;
Audio Accessories: True wireless earbuds, small Bluetooth speakers, and portable microphones;
IoT & Sensors: Mini Bluetooth beacons, temperature/humidity sensors, and asset trackers;
Medical Devices: Fingertip pulse oximeters, portable glucose monitors, and small health patches.
