TP4056 Module Price in Pakistan | Li-lon Battery Charger 1S 2A

Battery charging is the process of restoring energy to a rechargeable battery by passing an electric current through it. The charging process depends on the type of battery (e.g., Li-ion, NiMH, Lead Acid) and requires controlled voltage and current to ensure efficiency and safety. Overcharging or improper charging can damage batteries or cause overheating.Chip.pk give best TP4056 Module Price in Pakistan.

TP4056 Charging Module:-

The TP4056 is a widely used Lithium-Ion (Li-ion) and Lithium-Polymer (Li-Po) 1S Battery Charger Module. It is a small, inexpensive, and efficient linear charger IC designed for single-cell (3.7V) Li-ion batteries. The module provides a constant current and constant voltage (CC/CV) charging method.

Features of TP4056 Module :

1. Micro-USB and Type-C Input – Can charge batteries via USB power sources.
2. Constant Current/Constant Voltage (CC/CV) Charging – Ensures safe and efficient charging.
3. Overcharge & Over-discharge Protection – Prevents damage to the battery.
4. Automatic Charging Cutoff – Stops charging when the battery is fully charged.
5. LED Indicators:
   • Red LED (Charging)
   • Blue/Green LED (Fully Charged)

TP4056 Technical Specifications:

• Input Voltage: 4.5V – 5.5V (USB Power)
• Charging Current: 1A (Adjustable via resistor)
• Charge Cutoff Voltage: 4.2V ± 1%
• Battery Protection: Overcharge, Over-discharge, and Short Circuit Protection
• Size: Small PCB (~ 25mm x 19mm)

How TP4056 Works?

1. Connect a 3.7V Li-ion battery to the B+ and B- terminals.
2. Supply 5V power through the micro-USB or IN+ and IN- terminals.
3. The module charges the battery using CC/CV mode:
   • First, it supplies constant current until the battery reaches 4.2V.
   • Then, it switches to constant voltage mode and gradually reduces the current.
   • Once the current drops below a certain level, charging stops automatically.

Common Applications:

• Power banks
• DIY electronics projects
• Portable battery-powered devices
• Solar battery charging systems

TP4056 Battery Charging Module – In-Depth Explanation

The TP4056 is a compact and efficient Li-lon Battery Charger module designed for 3.7V Li-ion and Li-Po batteries. It provides safe and optimized charging using a constant current (CC) and constant voltage (CV) charging method. The module ensures that the battery is charged safely without overcharging or over-discharging.

1. Working Principle of TP4056

The TP4056 module operates in three stages to charge a Li-ion or Li-Po battery efficiently:

(A) Trickle Charge (Pre-Charge) Mode

• If the battery voltage is below 2.9V, the module charges the battery slowly at a lower current (~130mA) to prevent damage.
• This helps recover deep-discharged batteries safely.

(B) Constant Current (CC) Mode

• Once the battery reaches 2.9V, the module supplies a constant current (~1A by default) to charge the battery rapidly.
• The red LED remains ON during this stage.

(C) Constant Voltage (CV) Mode

• As the battery approaches 4.2V, the charging current gradually decreases while maintaining the voltage at 4.2V.
• When the current falls below 1/10th of the set charging current (~100mA if charging at 1A), the battery is considered fully charged, and charging stops.
• The green/blue LED lights up, indicating a full charge.

(D) Automatic Cutoff

• Once the battery is fully charged, the TP4056 stops supplying current to prevent overcharging.
• The module will restart charging if the battery voltage drops below a certain threshold (around 4.0V).

3. Additional Features & Modifications

(A) Charging Current Adjustment

By default, the TP4056 charges at 1A, but you can change the current by replacing resistor R3:

• 1A (Default) → 1.2kΩ
• 500mA → 2.4kΩ
• 250mA → 4.7kΩ
• 130mA → 10kΩ

(B) Battery Protection (TP4056 + DW01 + 8205A FETs)

• Some TP4056 modules include a battery protection circuit (DW01 + 8205A MOSFETs) that prevents:
  • Overcharging (>4.2V)
  • Over-discharging (<2.4V)
  • Short circuits & Overcurrent
• These modules provide an OUT+ and OUT- output that can be used to power external devices safely.

(C) Parallel Charging for Higher Capacity

• If you need higher battery capacity, you can connect multiple 3.7V Li-ion cells in parallel.
• However, do not charge multiple batteries in series, as TP4056 is designed for single-cell operation.

5. Precautions & Best Practices

⚠ Avoid Overloading the Module: TP4056 can handle only up to 1A charging current; higher loads can overheat the module.
⚠ Use a Proper Power Source: Provide a regulated 5V supply (USB adapter, solar panel, etc.) for safe charging.
⚠ Ensure Good Heat Dissipation: The module gets warm during charging; avoid placing it in enclosed spaces.
⚠ Always Use a Protected Li-ion Battery if your module does not have built-in protection.
