HCY 701435 3.7V 600mAh 25C Lithium Polymer LiPo Pouch Cell Drone Battery with 2-Pin Connector

1. Product Overview

The HCY 701435 3.7V 600mAh 25C Lithium Polymer battery is a compact rechargeable LiPo pouch cell intended for portable electronic and high-discharge applications.

The actual battery shown is marked HCY 701435, 3.7V, 600mAh and 25C. Based on its nominal voltage and rated capacity, it provides approximately 2.22Wh of energy.

Its slim pouch construction, flexible wire leads and pre-fitted 2-pin connector make it convenient for compact battery-powered devices and custom electronics projects.

Understanding the 701435 Size Code

The model code generally represents the approximate bare-cell dimensions:

• 70 → approximately 7.0 mm thickness
• 14 → approximately 14 mm width
• 35 → approximately 35 mm length

The complete finished battery can be slightly larger due to insulation, tabs, wires, connector and any protection/interface circuitry.

4. 25C High-Discharge Rating

The battery is marked 25C, indicating that it is designed for applications requiring comparatively higher discharge capability than ordinary low-current pouch cells.

This makes it suitable for compatible applications such as:

• Mini drones
• RC aircraft
• RC toys
• Robotics
• Small motor-driven projects
• Portable high-power electronics

I would not advertise an exact maximum current in amps unless you have the HCY datasheet for this specific 600mAh variant, because the 25C marking alone does not tell us the manufacturer’s permitted continuous/peak conditions.

5. Suitable Applications

This battery may be suitable for compatible:

• Mini drones and quadcopters
• RC helicopters
• RC aircraft
• RC toys
• Robotics
• Portable electronic devices
• Embedded systems
• DIY electronics
• Battery replacement applications
• Small rechargeable products

Compatibility depends on the device’s voltage, current requirement, dimensions, connector and polarity.

6. Charging & Usage

This is a single-cell 3.7V LiPo battery and should only be charged using a charger designed for 1S Lithium-ion / Lithium Polymer batteries.

Before use:

• Confirm correct polarity
• Confirm connector compatibility
• Confirm the equipment’s current requirement
• Use a suitable 1S LiPo charging circuit
• Do not use a charger intended for another chemistry or cell count
• Do not exceed the manufacturer’s permitted charging/discharge limits

7. Advantages of LiPo Pouch Cells

• Compact and lightweight design
• Flat form factor for space-limited products
• Rechargeable
• High energy density
• Flexible wire connection
• Suitable for portable electronics
• High-discharge variants suitable for motor-driven applications

8. Compatibility Note

Before ordering, verify:

• Nominal voltage: 3.7V
• Capacity: 600mAh
• Discharge rating: 25C
• Nominal cell size: approx. 7 × 14 × 35 mm
• Connector type
• Connector polarity
• Wire orientation
• Required current
• Available installation space

Having the same voltage and capacity does not automatically guarantee compatibility.

9. Safety Note

Lithium Polymer batteries require careful handling.

• Do not puncture or crush the pouch
• Do not bend or deform the cell
• Do not short-circuit the wires
• Do not reverse polarity
• Do not expose to fire or excessive heat
• Do not use a swollen, leaking or physically damaged battery
• Always use a compatible LiPo charger
