Haisito 12V/24V 20A Battery Charger & Maintainer for LiFePO4 and Lead‑Acid — 7‑Stage Smart with Temp Sensor

Haisito's 12V/24V 20A charger is a smart, seven-stage battery charger and maintainer designed to charge, trickle and revive a wide range of 2–200Ah batteries including LiFePO4 and lead‑acid types.

This compact charger combines automatic multi‑stage charging, selectable current levels and built‑in safety sensors to deliver controlled charging across cars, trucks, motorcycles, lawn gear and more. It supports 110–240V input, offers three adjustable output currents, and includes special modes for pulse repair and forced charging when cells are deeply discharged or misidentified.

How does Haisito protect my battery during charging?

The charger uses temperature sensing and multiple electronic safeguards to reduce risk while charging. It monitors temperature and voltage, prevents short circuits and overcurrent, and steps through a seven‑stage routine that optimizes charge acceptance without overstressing the battery.

• Built‑in temperature sensor with safe operation from −10°C to 40°C.
• Low‑voltage, overvoltage and overcurrent protections.
• Short‑circuit and electrostatic spark protection for safer connections.
• Seven‑stage charging algorithm for controlled, complete charging cycles.

Which battery types and vehicles will this charger work with?

Haisito's charger is engineered for broad compatibility: lead‑acid variants (AGM, GEL, EFB, flooded) and modern lithium chemistries including LiFePO4 are supported. It’s suited for automotive batteries as well as smaller and utility applications like motorcycles, golf carts, lawn mowers and light commercial equipment.

• Supports 12V and 24V systems with automatic detection.
• Rated for batteries from about 2Ah up to 200Ah.
• Compatible with cars, trucks, motorcycles, electric bikes, boats, tractors and forklifts.
• Specific LiFePO4 mode included for safer lithium charging.

What charging speeds and modes can I choose?

You can pick from three adjustable current settings to match battery capacity and desired charging speed. The unit offers trickle/maintenance modes, a pulse repair feature to revive sulfated batteries, and a forced charging option to start very low‑voltage cells.

• Three current options: 12V/5A, 12V/10A, 12V/20A (respective 24V: 3A, 5A, 10A).
• Trickle charge/maintainer stage for long‑term battery conditioning.
• Pulse repair to help recover weak or sulfated lead‑acid batteries.
• Forced charge mode (hold button 5 seconds) for deeply discharged or misread batteries.

How easy is it to use and install?

The charger is designed for owner use with clear mode selection and plug‑in operation for standard mains. Attach the clamps or ring connectors, select the appropriate voltage and current, and the unit will manage the rest through its automatic stages—monitoring and finishing with a maintenance trickle.

• Input: 110–240V—works in a variety of locations and outlets.
• User‑selectable voltage/current with simple button controls.
• Includes clamps for quick temporary connection and ring terminals for permanent installs.
• LED or display indicators show charging stages and status (refer to manual).

Who is this for: The Haisito 12V/24V 20A smart charger is aimed at vehicle owners, small‑fleet operators, and DIYers who need a versatile, safety‑focused charger and maintainer. It fits households with mixed battery types—cars, motorcycles, lawn equipment, small boats and electric utility vehicles—especially where occasional deep discharge or long‑term storage maintenance is expected. Choose this if you want selectable charging speeds, LiFePO4 compatibility and built‑in protections for dependable battery care.
