12.6V 5A Auto Cut Li-ion Battery Charger Price in Bangladesh

The 12.6V 5A Auto Cut Li-ion Battery Charger 63W is a dedicated charging adapter designed for compatible three-cell-series (3S) conventional lithium-ion battery packs. It provides a maximum charging voltage of 12.6V DC and a rated output current of up to 5A, making it suitable for battery-powered electronics and compatible rechargeable equipment.

A conventional 3S lithium-ion battery pack has a nominal voltage of approximately 11.1V and reaches 12.6V when fully charged. A charger designed specifically for this configuration uses an appropriate charging profile to control current and voltage throughout the charging process.

The charger’s automatic cut-off or charging-termination function helps prevent continued charging beyond the intended charging stage. Depending on the model, an LED indicator may show charging and full-charge status. Some versions also include protection against overcurrent, overvoltage or short circuits, so the exact protection features should be confirmed for the supplied unit.

With its 63W rated output, this charger is useful for compatible battery packs used in portable electronics, DIY projects and other low-voltage equipment.

What Is an Auto Cut Li-ion Battery Charger?

An auto cut lithium-ion battery charger uses charging-control circuitry to manage the charging process and terminate or transition charging when the appropriate condition is reached.

Many lithium-ion chargers use a Constant Current / Constant Voltage (CC/CV) charging method. During the constant-current stage, the charger supplies controlled current. As the battery approaches its target voltage, the charger maintains the specified voltage while the charging current gradually decreases.

Automatic charging control is important because lithium-ion batteries require a suitable charging voltage and current. A charger must match the battery’s chemistry and series-cell configuration.

Key Features

• 12.6V DC output: Designed for compatible 3S conventional lithium-ion packs.
• Up to 5A charging current: Supports charging at the rated current when the battery and charger conditions permit.
• 63W rated output: Provides substantial charging power for compatible battery packs.
• Automatic charging control: Helps manage the charging process.
• CC/CV charging method: Commonly used for conventional lithium-ion battery charging.
• Charging status indication: Some versions use LED indicators to show charging status.
• Compact adapter format: Convenient for compatible battery-powered equipment.
• Electronics project compatibility: Useful for suitable rechargeable battery packs in DIY applications.
• Dedicated voltage rating: Avoids using an unsuitable generic power adapter for charging.
• Practical charging solution: Suitable when the battery specification matches the charger’s output and charging profile.

Technical Specifications

Specifications such as AC input range, connector polarity, indicator behavior and individual protection features should be verified against the exact product version.

Working Principle

The charger converts AC input power into a controlled DC output suitable for charging a compatible battery pack.

During charging, its control circuitry regulates current and voltage according to the charging profile. In a CC/CV design, current is controlled initially, while the voltage is maintained at the specified limit as charging progresses.

When the battery reaches the appropriate end-of-charge condition, the charger may terminate charging or change its output behavior, depending on its design. The indicator may change color to show the charging status.

A charger rated at 12.6V is intended for conventional 3S lithium-ion batteries, not every battery described as a “12V battery.” LiFePO4 and lead-acid batteries use different charging requirements.

Applications

For compatible rechargeable battery packs with an 11.1V nominal voltage and 12.6V full-charge voltage.

2. Portable Electronics

Suitable for equipment that uses a compatible 3S lithium-ion battery pack.

3. DIY Electronics Projects

Useful for appropriately designed rechargeable power systems.

4. Robotics Projects

Can charge compatible battery packs used in low-voltage robotics equipment.

5. Battery-Powered Devices

Suitable for compatible devices with matching battery chemistry, voltage and charging requirements.

6. Electronics Prototyping

Useful for projects involving rechargeable lithium-ion battery packs.

Advantages

Dedicated charging voltage: The 12.6V output is appropriate for conventional 3S lithium-ion packs.

High rated current: A maximum rated current of 5A can reduce charging time when the battery supports that charging rate.

Automatic charging control: Helps manage the charging process without relying solely on manual disconnection.

CC/CV charging: Provides a standard charging approach for conventional lithium-ion batteries.

Convenient adapter design: Offers a straightforward charging option for compatible battery equipment.

Limitations

• It is not suitable for every battery marketed as 12V.
• It must not be used with a 4S lithium-ion pack or a 4S LiFePO4 pack unless the battery manufacturer explicitly specifies compatibility.
• The battery must support the charger’s maximum charging current.
• The advertised automatic cut-off function does not replace appropriate battery protection.
• Connector dimensions, polarity and built-in protections vary by model.
• Actual charging time depends on battery capacity, initial state of charge, temperature and the battery’s permitted charging current.

Installation and Usage Tips

1. Confirm that the battery is a conventional 3S lithium-ion pack with a 12.6V full-charge voltage.
2. Check the battery manufacturer’s recommended charging current before using a 5A charger.
3. Verify connector size and polarity before connecting the charger.
4. Use a compatible battery protection system as specified by the battery manufacturer.
5. Charge in a dry, well-ventilated location and follow the battery manufacturer’s instructions.
6. Do not use a damaged, swollen or unusually hot battery.
7. Avoid covering the charger during operation.
8. Do not leave charging batteries unattended or near flammable materials.
9. Disconnect the charger if abnormal heating, smell or other unusual behavior occurs.
10. Do not assume the charger is compatible with LiFePO4, lead-acid or other battery chemistries.
