20A Smart Battery Charger 12V 24V LiFePO4 Lead Acid Maintainer with Booster Mode
High current output supports faster battery charging
The 20A Smart Battery Charger is designed for 12V and 24V battery systems, combining fast charging, battery maintenance, pulse repair, and trickle charging functions in one device. With 20A output for 12V batteries and 10A output for 24V batteries, it provides powerful charging performance for different battery applications.
Supporting LiFePO4 and lead-acid batteries including AGM, GEL, marine, and deep-cycle batteries, this charger is suitable for cars, trucks, motorcycles, boats, lawn mowers, tractors, golf carts, RVs, and other compatible vehicles.
Adjustable charging levels meet different battery requirements
The charger features five adjustable current settings including 2A, 6A, 10A, 15A, and 20A. Users can manually select the suitable charging current according to battery condition and charging needs.
With a 10-stage smart charging process, the charger manages multiple charging steps including battery detection, desulfation, pre-charging, bulk charging, constant current, absorption, float charging, and restart functions.
Emergency boost mode provides additional power support
The charger includes a 200-second booster mode that increases current output to help quickly add battery power when needed. This function provides additional charging assistance for batteries requiring higher current support.
The booster mode is not a jump starter and cannot activate completely dead batteries.
Pulse repair function helps maintain battery performance
The charger uses high and low frequency pulse technology to detect battery sulfation and acid stratification. The repair function helps restore the performance of old or idle lead-acid batteries and supports improved battery condition.
When the battery has charging difficulties, users can select repair mode for maintenance. This function is designed for battery recovery and cannot repair fully damaged batteries.
Smart temperature control adapts to climate changes
The charger features summer and winter temperature modes that automatically adjust charging voltage according to environmental conditions. Summer mode activates above 28°C, while winter mode activates below 10°C.
This temperature compensation system helps maintain suitable charging performance by adjusting charging control in different weather conditions.
Large screen monitoring makes charging information easier to view
The oversized LED display provides real-time charging information, including voltage, current, internal temperature, charge percentage, summer mode, and winter mode. The clear screen allows users to monitor battery status during charging.
The charger is equipped with multiple protection systems including short-circuit protection, electric shock protection, low-voltage protection, overheating protection, cooling system, flame-retardant materials, overcharge protection, overcurrent protection, reverse connection protection, child safety lock, and false touch protection.

Automatic maintenance keeps batteries ready for use
After the battery reaches full charge, the charger automatically switches to trickle or float charging mode. This low-current maintenance process helps compensate for natural battery discharge during storage.
With adjustable current control, intelligent detection, pulse repair technology, temperature compensation, and multiple safety functions, the 20A charger provides a practical solution for maintaining different 12V and 24V battery systems.
