Jiangxi Huahao HH 146074 3.85V 10000mAh High-Voltage Lithium Polymer LiPo Pouch Cell with Metal Tabs – 38.5Wh

1. Product Overview

The Jiangxi Huahao HH 146074 is a high-capacity 3.85V, 10000mAh rechargeable lithium polymer pouch cell with a rated energy of 38.5Wh.

This is a high-voltage lithium cell designed for compatible equipment using a maximum charging voltage of 4.4V. It must not be treated as a conventional 3.7V LiPo cell with a 4.2V charging limit.

The cell is supplied with exposed metal tabs and does not have a wire lead or connector fitted. A protection PCB is not visible and must not be assumed to be included. Suitable protection, charging and power-management circuitry must be provided in the final battery assembly.

3. Physical Specifications

The dimensions above represent the nominal cell body. Actual finished size may vary because of pouch tolerances, folded edges, insulation tape and protruding metal tabs. Measure the supplied cell and installation space before use.

4. Standards and Markings

The battery carries the following visible markings:

• IS 16046 (Part 2):2018
• IEC 62133-2:2017
• BIS registration number: R-41256528
• CE marking
• Recycling symbol
• Crossed-out wheeled-bin disposal symbol
• Manufacturer: Jiangxi Huahao New Energy Co., Ltd.
• Model: 146074
• Nominal voltage: 3.85V
• Rated capacity: 10000mAh
• Rated energy: 38.5Wh
• Manufacturer code: PB-251

5. Suitable Applications

This cell may be suitable for compatible:

• High-capacity power banks
• Fast-charging portable power products
• Portable speakers and audio equipment
• Tablet computers and portable displays
• Portable electronic instruments
• Backup power modules
• Custom rechargeable electronics
• Battery-development and repair applications
• Equipment designed for a 3.85V high-voltage lithium cell

The cell is not a ready-to-use battery pack. It requires suitable electrical connections, protection circuitry and a compatible charging system.

6. Charging and Usage

• Charge only with a lithium charging circuit specifically designed for a 3.85V cell with a maximum charging voltage of 4.4V.
• Do not use a charger designed only for conventional 3.7V/4.2V LiPo cells if full rated capacity is required.
• Never exceed the 4.4V maximum charging voltage.
• Verify the polarity of both metal tabs before making any connection.
• Use a suitable 1S protection PCB or battery-management circuit in the final assembly.
• Confirm the cell’s charging and discharge-current ratings before use.
• Use properly designed tab-welding or connection methods.
• Insulate the tabs and all electrical joints after assembly.

7. Compatibility Note

Before purchasing or installing this cell, verify:

• 3.85V nominal battery compatibility
• 4.4V full-charge compatibility
• Battery compartment dimensions
• Actual finished cell thickness
• Tab positions and polarity
• Required output connection
• Charging-circuit compatibility
• Equipment operating and peak current
• Protection-circuit requirements
• Available space for the protruding tabs

A 3.85V high-voltage cell is not directly interchangeable with every 3.7V LiPo battery. The charging voltage, protection circuit, dimensions, tab arrangement and current capability must all match the equipment.

8. Safety Note

• Do not short-circuit the exposed metal tabs.
• Insulate the tabs during storage and transportation.
• Do not puncture, crush, bend or open the battery pouch.
• Do not overcharge or use an incompatible charger.
• Keep away from fire, water, excessive heat and conductive objects.
• Do not use the cell if it is swollen, leaking, damaged or unusually hot.
• Do not solder directly to the pouch body.
• Avoid repeated bending or mechanical stress on the metal tabs.
• Assembly should be performed only by a person familiar with lithium battery construction and safety.
