KP F02 704573 3.7V 4500mAh Lithium Polymer LiPo Rechargeable Battery with Bare Wires – 16.65Wh

1. Product Overview

The KP F02 704573 is a 3.7V, 4500mAh rechargeable lithium polymer pouch battery providing 16.65Wh of nominal energy. Its flat construction makes it suitable for compatible portable electronics, power banks, Bluetooth devices, GPS equipment, IoT products and DIY electronic projects.

The battery is supplied with red and black output wires with bare ends, allowing a suitable connector to be installed according to the application. A protection PCB is visibly fitted along one edge of the battery; however, its exact protection functions and current rating are not specified.

This is not a verified high-discharge battery. Confirm the operating and peak-current requirements of the equipment before use.

3. Physical Specifications

The finished battery size may vary slightly because of the pouch, protection PCB, insulation tape, wires and manufacturing tolerances. Measure the battery compartment and the supplied battery before installation in a tight enclosure.

4. Suitable Applications

This battery may be suitable for compatible:

• Power banks and portable backup devices
• Tablet computers and portable media players
• Bluetooth speakers and wireless devices
• GPS and tracking equipment
• IoT and smart devices
• Portable electronic instruments
• Arduino, ESP32 and NodeMCU projects
• DIY electronics and prototypes
• Replacement applications matching its specifications

Suitability depends on the equipment’s voltage, charging system, physical space and current requirements.

5. Charging and Usage

• Charge only with a compatible 1S lithium-ion/LiPo charging circuit.
• Maximum full-charge voltage must not exceed 4.2V.
• Do not connect the battery directly to a 5V USB supply without a suitable LiPo charging controller.
• Observe the correct polarity: red is positive and black is negative.
• Fit the required connector securely and insulate all exposed conductors.
• Do not use the battery where the equipment’s operating or peak current exceeds the battery or protection-board rating.
• Avoid pulling, twisting or placing mechanical stress on the wires.

6. Compatibility Note

Before purchasing or installing this battery, verify:

• 3.7V nominal battery compatibility
• 4.2V full-charge compatibility
• Required battery capacity
• Available installation space
• Battery dimensions
• Equipment operating and peak current
• Wire polarity
• Required connector type
• Charging-circuit compatibility
• Protection-board requirements

Matching voltage and capacity alone do not guarantee compatibility. The battery’s dimensions, polarity, current capability and charging requirements must also match the equipment.

7. Safety Note

• Do not puncture, crush, bend or open the battery pouch.
• Do not short-circuit the wires.
• Do not overcharge or use an incompatible charger.
• Keep away from fire, water, excessive heat and conductive objects.
• Do not use the battery if it is swollen, leaking, damaged or unusually hot.
• Insulate the bare wire ends during storage and transportation.
• Installation should be performed by a person familiar with lithium battery wiring and safety.
