Output power: = Input voltage * 30A. For example, 12V input * 30A = 360W. At 12V input, the power is 360W.

For example, 24V input * 30A = 720W. That is, at 24V input, the power is 720W.

Power Explanation to the Boost Step UP Converter:

Since the input current of this power supply is 30A at 10-30V and 2 at 31-60V, the output power is related to the input voltage. Higher input voltages produce higher power.

(Input voltage * input current equals total power.) For example, 12V input * 30A produces 360W. 24V input * 30A produces 720W. At 36V input, the input current is 2, resulting in a power output of 900W.


Default delivery of the boost up converter module


Output voltage approximately 19V, current approximately 30V, undervoltage protection approximately 10.5V. If you require a factory adjustment to a different voltage, please specify this when placing an order and contact us.

This product is designed to boost the voltage of lead-acid batteries, lithium batteries, solar cells, or power supplies for electric vehicles and battery charging. It offers powerful functions.


1. For example, if the original battery of an electric vehicle is 48V, it can be boosted to 60V to power the vehicle, thereby increasing the vehicle's speed and acceleration.

2. Charge your electric bicycle. (1. For example, if you have an unused 12V or 24V battery, this booster can boost the voltage and charge the original battery, effectively acting as a power bank for your electric vehicle. 2. The input can also be connected to solar cells, wind power, generators, and other power sources to boost the voltage and charge the original battery, increasing the vehicle's range.)

3. It can boost the battery voltage to increase the vehicle's speed. The recommended voltage should not exceed 10V.

4. Boost and stabilize the solar panel voltage.


Voltage Adjustment of the Boost Step UP Converter:


With the power supply connected and no load, use a flat-blade screwdriver to adjust the output "V-ADJ" potentiometer (marked in the image below) clockwise to increase the setting and counterclockwise to decrease the setting. Due to the large output capacitor, the output voltage will react slowly when switching from a high voltage to a low voltage. We recommend using smaller adjustment increments. (The default output voltage is set to 19V for shipment. Please specify or leave a message if you require a different voltage setting.)


Input Low Battery Protection Adjustment of the Boost Step UP Converter:


Low battery protection is primarily intended for battery input, preventing over-discharge and low battery voltage from damaging the power module and battery. Low voltage protection is also required when the input is a switching power supply.

Method 1: For example, to set low battery protection for a 12V battery, connect a 10V voltage to the power module input and use a flat-blade screwdriver to adjust RV1 (clockwise to increase the protection voltage, counterclockwise to decrease it) until the UVLO light illuminates. At this point, the low battery protection voltage is 10V. When the battery voltage drops below 10V, the power module will not boost (the input voltage is equal to the output voltage). Only when the input voltage exceeds 10V will the power supply automatically recover and start boosting.

Method 2: The Boost Step UP Converter Module Connect a battery or switching power supply to the input. If the UVLO light on the board is off, turn the RV1 potentiometer counterclockwise to illuminate it. Once it illuminates, turn it two full turns clockwise. If the UVLO light is on, turn the RV1 potentiometer clockwise to turn it off. Turn it two more turns after turning it off. (Applicable to voltages between 8V and 45V)
