With HTRC chargers, you are always supported during work: a precise and reliable choice.

【One-Button Start】The 12V 20Amp, 24V 10Amp battery charger features four modes that can be started with a single button press, with a maximum charging current of 20A, providing fast charging for the battery. It has accidental touch protection, automatically locking 10 seconds after charging starts to prevent accidental touches. Thanks to its small size, it is a portable car battery charger.

【3-Level Adjustable Current】With the car battery charger, you can choose the appropriate charging current, selecting from (12V/5A, 24V/3A) → (12V/10A, 24V/5A) → (12V/20A, 24V/10A). Please select the current strength that meets your battery charging needs.

【Wide Application Range】The trickle charger can be used for various types of batteries, such as lithium, LiFePO4, lead-acid (PB/AGM/GEL/EFB, MF, FLOODED, VRLA, SLA, wet batteries). It is applicable for cars, golf carts, motorcycles, electric motorcycles, motorboats, lawnmowers, forklifts, tractors, etc. Only lithium batteries equipped with BMS can be charged!

【Trickle Charging & Maintenance/Pulse Repair】The maintenance/pulse repair function activates the battery, and the unique battery protection function allows for fast and safe charging, while trickle charging provides perfect final protection for fully charging the battery.

【Temperature Sensing & Multiple Protection】It has a built-in temperature sensor, capable of charging normally from -10°C (14°F) to 40°C (104°F). It is equipped with various built-in protections, such as temperature protection, low voltage protection, over-voltage protection, short-circuit protection, over-current protection, and electrostatic spark protection. This allows for worry-free charging.

We provide a 1-year warranty.

20 Amp Intelligent Battery Charger
Question 1: Not reaching the maximum charging current?
For battery protection, the system automatically identifies the battery voltage and selects the most suitable current for charging the battery. When the battery voltage is low (for example, if the voltage of the 12V battery is less than 11V), the system automatically charges the battery with the maximum current. (Charging current adjustable in 3 levels, high current, fast charging)

Question 2: The LiFePO4 battery is not fully charged?
When the battery is fully charged, it has a recall function that reduces the charge by about 1V, which is normal. It adds a smaller current after full charge for continuous charging.

Schematic of different charging states:

Charging voltage & Current: Real-time voltage or current display
Repair mode: Battery repair
Temperature:

Winter. when the temperature is below -10°C (14°F), increases the charging voltage
Summer. when the temperature is above +40°C (104°F), decreases the charging voltage

Test mode: When the battery is nearly fully charged, it automatically continues to charge the battery in trickle mode.
Full charge: When the battery is fully charged, "FULL" appears
Low voltage: The battery voltage is too low or cannot hold energy
