High-Voltage 4S 14.8V 650mAh 14430 Li-ion Battery PACK for Measurement Instruments

• 650mAh Balanced Runtime with 14.8V High Voltage: Delivers 9.62Wh of stable energy, perfectly tailored for compact high-power devices: supporting a mini drone (micro size) for 8-12 minutes of flight time, a handheld laser level for 3-4 hours of continuous use, a small industrial sensor for 5-7 days (low-power mode), or a portable audio amplifier for 2-3 hours of playback. Ideal for scenarios where high voltage, portability, and consistent runtime are mutually critical.
• 14430 Miniature Cells & 4S Stability: Adopts 14430 cylindrical li-ion cells, renowned for their ultra-small footprint and excellent energy density for micro devices. The 4S series configuration precisely aggregates voltage to 14.8V, with built-in cell balancing to ensure uniform current distribution and steady output—avoiding voltage fluctuations that may damage precision equipment. Weighing only 80g with a slim profile, it seamlessly integrates into tight device enclosures without adding excess bulk.
• Comprehensive Safety Protection: Equipped with a high-precision built-in Protection Circuit Module (PCM) that provides multi-layer safeguards: over-charge protection (cuts off at 16.8V), over-discharge protection (shuts down at 11.2V), short-circuit protection, over-current protection, and over-temperature protection. The 14430 cells’ inherent thermal stability eliminates risks of leakage, swelling, or thermal runaway, ensuring safe use in industrial, consumer, and professional scenarios.

• Micro Drones & RC Devices: Mini consumer drones, micro RC cars, and small RC helicopters (high-voltage motor needs).
• Precision Tools: Handheld laser levels, small laser rangefinders, and portable precision measuring equipment.
• Industrial & IoT Sensors: High-voltage industrial sensors, wireless monitoring devices, and compact IoT transmitters.
• Portable Electronics: Small audio amplifiers, handheld gaming devices (mini models), and portable high-power LED lights.
• DIY & Professional Projects: Custom micro drone builds, high-voltage Arduino projects, and small precision equipment prototypes.
