In today’s world, where vehicles and equipment rely heavily on efficient battery performance, having a reliable charger is essential. The Haisito EF-20 Smart Battery Charger stands out as a high-performance charging solution for 12V and 24V batteries, including LiFePO4, Lithium, and Lead-Acid (AGM/Gel/SLA) types. Whether you need to charge a car, boat, motorcycle, lawn mower, or golf cart, this charger delivers fast, safe, and intelligent charging with multiple protection features.

Key Features & Performance

1. One-Button Start & Adjustable Charging Current

The EF-20 charger is designed for ease of use with a one-button start function. Once activated, it automatically detects the battery type and adjusts the charging process accordingly. Users can also manually select from three charging current levels:

  • 12V (5A, 10A, 20A)
  • 24V (3A, 5A, 10A)

This flexibility allows for fast charging when needed or a slower, more controlled charge for battery maintenance.

  • Designed for cars, motorcycles, boats, tractors, forklifts, and more

This makes it a universal charging solution for both personal and professional use.

3. Trickle Charge & Pulse Repair Function

One of the standout features is its trickle charge mode, which prevents overcharging and maintains battery health. Additionally, the pulse repair function helps revive sulfated batteries, extending their lifespan.

4. Advanced Safety & Protection

Safety is a priority with built-in protections:

  • Overvoltage & Undervoltage Protection
  • Short-Circuit & Overcurrent Protection
  • Temperature Detection (-10°C to 40°C operation)

The charger also locks automatically after 10 seconds to prevent accidental adjustments.
