Charging 12v bike battery using 5v phone adapter.

Charging 12v bike battery using 5v phone charger and step-up boost converter.

Requirements

1) 5V phone adaptor with USB cable.

2) DC-DC Step-up Boost converter.

3)Two Alligator Clips.

4)Two normal wires.



About DC-DC Adjustable Step-up Boost Power Converter Board Module


  1. Wide input voltage from 5V - 32V
  2. The module has a wide Output Voltage range from 1.25V - 35V
  3. Efficient MOSFET switches enable efficiency up to 94%
  4. Input Current of module- 3A maximum, no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current)
  5. The Switching frequency of module -400KHz



The connection of the circuit is simple as follows


Connect the 5v output of the phone adaptor using a USB cable to the input of the DC-DC Step-up Boost converter.

            DC-DC Step-up Boost converter.

Connect +ve wire(red) of the USB cable to +ve of DC-DC Step-up Boost converter and -ve wire(black) of the USB cable to -ve of DC-DC Step-up Boost converter at the input of the module.


           


Connect the output of the DC-DC Step-up Boost converter module to +ve of the module to +ve of battery terminal and -ve of the module to the -ve terminal of the battery as shown in the video.

The output voltage of the module should be the charging voltage of the battery as specified on the battery specifications.

Adjust the out voltage of the module using the potentiometer on the DC-DC Step-up Boost converter module as shown in the video.

The charging time of the battery will be 10-12hrs for a full charge and also based on the specifications of battery current requirements. For example 12v/7ah battery.


Precautions while charging 12v bike battery

  1. Always handle batteries with care.
  2. Do not short circuit the battery terminals. 
  3. Never overfill with acid.
  4. Never allow children access to a battery.
  5. Always charge the battery in a properly well-ventilated area.
  6. Never allow the battery vents to become blocked.
  7. Always wear eye protection for safety.
  8. Always wear protective clothing.
