6P 18650 High-Capacity Design 3.6V 15300mAh Li-ion Battery Pack for UPS Backup

The BAKTH-18650CQ-1S6P-PACK is a premium ultra-high capacity lithium-ion battery pack, featuring a nominal 3.6V voltage (4.2V full charge), an exceptional 15300mAh capacity, and 55.08Wh energy output. Engineered with high-performance 18650CQ cylindrical li-ion cells and a stable 1S6P parallel configuration (6 cells in parallel), it integrates superior energy density, consistent low-voltage delivery, and rugged pack design—making it the ideal power source for backup power systems, portable medical devices, outdoor surveillance equipment, and high-demand devices that require prolonged, uninterrupted energy supply without compromising reliability.

Crafted to solve the pain points of short runtime and unstable power supply for long-duration use devices:

• 15300mAh Ultra-Long Runtime: Delivers 55.08Wh of stable energy, powering devices for extended periods: supporting a portable CPAP machine for 18-22 hours of continuous use, an outdoor security camera for 7-10 days (low-power mode), a handheld POS terminal for 24-30 hours of daily operation, or a mini UPS system for 8-12 hours of backup power for routers and small office equipment. Perfect for off-grid use, emergency scenarios, and professional work where frequent recharging is impractical.

• 18650CQ High-Quality Cells & 1S6P Stability: Adopts premium 18650CQ cylindrical li-ion cells renowned for excellent cycle life, high energy density, and thermal stability. The 1S6P parallel configuration enhances capacity while ensuring balanced current distribution and consistent 3.6V voltage output, avoiding sudden power drops that may damage sensitive equipment. This combination guarantees reliable performance even under continuous heavy load.

• 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 4.2V), over-discharge protection (shuts down at 2.75V), short-circuit protection, over-current protection, and over-temperature protection. The 18650CQ cells’ inherent stability, paired with the BMS, eliminates risks of leakage, thermal runaway, or explosion, ensuring safe use in critical scenarios like medical and emergency backup.

• Backup Power Systems: Mini UPS for routers, security cameras, home emergency devices, and small office equipment.

• Portable Medical Equipment: Portable CPAP machines, handheld diagnostic devices, small oxygen concentrators, and mobile medical carts.

• Outdoor & Surveillance Gear: Wireless security cameras, outdoor LED floodlights, portable camping equipment, and off-grid communication devices.

• Professional Devices: Handheld POS terminals, portable scanners, industrial sensors, and mobile data collectors.

• DIY & Industrial Projects: Custom backup power banks, off-grid Arduino projects, and small industrial equipment.
