High-Capacity 3.6V 6400mAH 18650CP 1S2P Lithium Battery Pack for High-Drain Portable Devices

The BAKTH-18650CP-1S2P-3J is a premium lithium-ion battery pack, featuring a nominal 3.6V voltage (4.2V full charge), an impressive 6400mAh high capacity, and 23.04Wh energy output. Engineered with high-performance 18650CP cylindrical li-ion cells and a stable 1S2P configuration (1 cell in series, 2 cells in parallel), it merges ultra-long runtime, consistent power delivery, and industrial-grade durability—making it the ideal power source for portable electronics, backup power systems, medical devices, and outdoor gear that demand extended, reliable energy supply without compromising portability.

Crafted to solve the pain points of low-capacity batteries and unstable power sources for long-duration use devices:

• 6400mAh Ultra-Long Runtime: Delivers 23.04Wh of stable energy, powering devices for prolonged periods: supporting a portable CPAP machine for 8-10 hours of continuous use, a handheld POS terminal for 12-15 hours of daily operation, an outdoor LED work light for 30+ hours, or a mini backup power bank for 2-3 full charges of smartphones. Perfect for on-the-go, outdoor, or emergency scenarios where frequent recharging is impractical.
• 18650CP High-Quality Cells & 1S2P Stability: Adopts premium 18650CP cylindrical li-ion cells renowned for excellent energy density, cycle life, and thermal stability. The 1S2P configuration ensures balanced current distribution and consistent voltage output, avoiding sudden power drops that may damage sensitive equipment. This combination guarantees reliable performance even under continuous load.

• Medical Equipment: Portable CPAP machines, handheld diagnostic devices, and small oxygen concentrators.
• Portable Electronics: Handheld POS terminals, portable scanners, and professional audio recorders.
• Outdoor Gear: LED work lights, portable camping stoves, and outdoor monitoring equipment.
• Backup Power Systems: Mini UPS for routers, security cameras, and home emergency devices.
• DIY & Industrial Devices: Arduino-based projects, small electric tools, and industrial sensors.
