BAKTH-585973P-1S-3J 3.85V 4400mAh Lithium Polymer Battery Pack for Smart Devices
The BAKTH-585973P-1S-3J is a premium high-voltage lithium-polymer battery pack, featuring a nominal 3.85V voltage (4.4V full charge), an impressive 4400mAh capacity, and 16.94Wh energy output. Engineered with high-performance 585973P soft-package Li-Polymer cells and a stable 1S configuration, it integrates ultra-thin flexible design, superior energy density, and consistent high-voltage delivery—making it the ideal power source for portable consumer electronics, handheld devices, and small precision equipment that demand long runtime, compact size, and reliable performance in a flexible form factor.
Technical Performance You Can Rely On

Engineered for consistent, stable performance in diverse daily use conditions: 

  • Stable 3.85V High-Voltage Output: Maintains a steady 3.85V nominal voltage throughout discharge, avoiding sudden power drops that cause device malfunctions, data loss, or premature shutdowns. Critical for sensitive portable electronics like smartphones, game consoles, and diagnostic devices, ensuring optimal performance until full depletion.
  • Wide Temperature Adaptability: Operates reliably from -20°C to 60°C, performing well in cold outdoor environments and warm indoor settings without compromising capacity or safety. Suitable for year-round use, whether traveling in cold climates or using devices in warm conditions. 
  • Comprehensive BMS Safety Protection: Equipped with a built-in high-precision Battery Management System (BMS) that provides multi-layer safeguards: over-charge protection (cuts off at 4.4V), over-discharge protection (shuts down at 3.0V), short-circuit protection, over-current protection, and over-temperature protection.
