What to know before buying

Listing details to confirm

The listing is inconsistent about output: its title and feature copy describe 12V/25A and 24V/13A, while the details section lists 12 Volts output and 24 Volts input. Confirm the intended voltage and current for your battery before purchase. The stated repair mode applies only to lead-acid batteries, not LiFePO4, and cannot repair severely damaged batteries. The listing also says operation is normal from -10°C(14°F) to 40°C(10°F), but the Fahrenheit endpoint conflicts with the Celsius value, so the usable temperature range is unconfirmed.

Who is it for?

A good fit for

Owners of compatible 12V or 24V vehicle batteries who want selectable charging current and automatic maintenance.
Drivers, boat owners and users of motorcycles or lawn equipment with compatible lead-acid or LiFePO4 batteries.

Less suited to

People needing a charger for e-bikes, e-scooters or other electric mobility devices.
Buyers who need confirmed output ratings or an unambiguous operating temperature range without first checking the listing.

Customer feedback reports ease of use, compact size and perceived charging performance, including a report of charging a 240 Ah leisure battery fully. Compatibility feedback is not uniform, with a customer noting difficulty using it with LiFePO4 batteries. That concern matters because the listing claims LiFePO4 support, while its output details are also inconsistent. The overall rating distribution leans positive but includes a meaningful spread of lower ratings, and does not establish specific causes.

Positive themes

Customers report that it is easy to use and charges quickly.
Feedback mentions compact size and perceived compatibility with batteries.

Mixed feedback

Compatibility feedback includes a report that the charger was not suitable for a LiFePO4 battery, despite the listing claiming support.

Frequently asked questions

Which battery types does the Haisito charger list as compatible?

The listing names LiFePO4 and lead-acid types including AGM, GEL, EFB, MF, VRLA, SLA and wet batteries. It is described for vehicle batteries, not e-bikes or e-scooters.

Three settings are given: 12V/2A and 24V/3A, 12V/15A and 24V/6A, or 12V/25A and 24V/13A. The details section separately lists output voltage as 12 Volts and input voltage as 24 Volts, so confirm the ratings before use.

Can its repair mode be used on LiFePO4 batteries?

No. The listing says pulse repair mode is only for lead-acid batteries and cannot repair severely damaged batteries.

What does the display show?

The listing says it displays charging percentage, battery voltage, charging current, internal temperature and error messages.
