Product Description
High-Capacity 3.7V 1400mAh 2P Li-ion Cell 752935 Design Battery Pack for Wearable Devices


The BAKTH-752935-2P-2 is a high-performance lithium-polymer (Li-Pol) battery engineered with a 2P parallel configuration (two cells in parallel), featuring a slim prismatic form factor (75mm × 29mm × 3.5mm), nominal 3.7V voltage (4.2V full charge), 1400mAh capacity, and 5.18Wh energy output. Designed to balance high capacity with ultra-thin design, this battery merges Li-Pol’s flexibility, lightweight construction, and stable performance—making it the ideal power source for mid-sized portable electronics, wearable chargers, IoT devices, and custom gadgets that demand extended runtime without sacrificing slim aesthetics.
Core Advantages of 2P Parallel Design & Li-Pol Technology
Crafted to solve the trade-off between capacity and size for modern devices:
  • 2P Parallel for Enhanced Capacity: Two high-quality Li-Pol cells in parallel double the capacity (from 700mAh to 1400mAh) while maintaining a stable 3.7V voltage, delivering 5.18Wh of reliable energy. This parallel configuration not only boosts runtime but also enhances current-carrying capacity (supports peak discharge up to 3A), making it suitable for devices requiring moderate burst power, such as portable speakers or mini drones.

1400mAh Long Runtime: Optimized for low-to-medium drain devices, delivering extended usage: powering a wireless earbud charging case for 8-10 full earbud charges, a mini Bluetooth speaker for 6-8 hours of continuous playback, a handheld scanner for 3-4 hours of active use, or an IoT environmental sensor for 3-6 weeks (depending on data transmission frequency). Perfect for all-day use and on-the-go lifestyles.

  • Lightweight & Space-Efficient: Weighing only 28-30g, it adds minimal bulk to portable devices—critical for gadgets that prioritize portability. Its flat profile maximizes space utilization, allowing for thinner device designs without compromising battery life.

Ideal For:

Portable Audio & Wearables: Wireless earbud charging cases, mini Bluetooth speakers, and mid-sized smartwatches.

Handheld Electronics: Handheld game consoles, portable scanners, digital cameras (compact models), and mini LED projectors.

IoT & Smart Home Devices: Mid-range Bluetooth beacons, environmental monitoring sensors, and smart doorbell backup power.

Custom Projects & Gadgets: DIY electronics, mini drones (mid-sized models), Arduino-based devices, and portable LED lights.

Emergency Backup: Small medical devices (e.g., portable pulse oximeters), emergency flashlights, and portable radios.
