Litime 48V 30A Lithium Battery Charger — 58.4V Output, 0V Reactivation, LiFePO4 Three‑Stage

The LiTime 48V 30A lithium battery charger is a purpose-built 58.4V AC‑DC charger for 51.2V (48V nominal) LiFePO4 battery banks that supports 0V reactivation and delivers up to 30A of charging current.

This compact, fan‑cooled LiTime charger provides a three‑stage charging profile (pre‑charge, constant current, constant voltage) tailored to LiFePO4 chemistry, plus multiple hardware protections and a convenient 50A Anderson output for faster hookup. It accepts a wide AC input (100–240V, 50/60Hz) so it works across regions, and includes CE and RoHS safety compliance as well as product liability insurance.

How does this charger restart a battery that reads 0V?

The LiTime unit includes a 0V activation feature that gives a gentle pre‑charge to deeply depleted LiFePO4 cells so they can return to a normal charging profile. This prevents immediate high‑current attempts on a dead battery and helps recover packs that otherwise wouldn’t accept charging.

• Dedicated 0V pre‑charge stage to slowly raise cell voltage.
• Automatic transition from pre‑charge to CC/CV when safe.
• Useful for batteries that have been left discharged for long periods.

What safety protections and certifications are built into the charger?

LiTime equipped this charger with multilevel protection circuits to reduce risk during charging and handling. The unit provides over‑temperature shutdown, output short‑circuit protection, reverse‑polarity protection, and over/under‑voltage safeguards to protect both the charger and connected batteries.

• CE and RoHS compliance for electrical safety and materials.
• Automatic CC → CV → float/cutoff charging sequence to prevent overcharging.
• Covered by AIG product liability insurance beginning May 22, 2026.

How fast does it charge and what battery sizes is it suited for?

The charger delivers up to 30A at a maximum output of 58.4V, making it well suited for 51.2V (48V nominal) LiFePO4 battery banks. Charging speed depends on battery capacity and state of charge; a larger amp‑hour battery will take proportionally longer but benefits from the charger’s consistent CC/CV profile.

• 58.4V maximum voltage tailored for 51.2V LiFePO4 packs.
• 30A maximum current—appropriate for medium to large battery banks.
• Fan cooling supports sustained charging at higher currents.

Are there any installation or usage limitations I should know about?

While robust, the charger is not waterproof and should not be used in marine or wet environments such as boats, yachts, or exposed trolling motor installations. It’s designed for indoor or sheltered installations with proper ventilation to allow the cooling fan to operate effectively.

• Not suitable for marine or underwater applications.
• Requires AC input 100–240V, 50/60Hz; check local supply compatibility.
• Includes heavy‑gauge cord and battery cables; use the 50A Anderson connector for fast, secure hookup.

Who is this for: The LiTime 48V 30A charger is aimed at homeowners, RV and off‑grid solar users, electricians, and installers who maintain 51.2V LiFePO4 battery banks and need a reliable, relatively fast AC‑to‑DC charger with 0V recovery and strong safety features. It’s a practical upgrade for anyone replacing lead‑acid chargers or seeking a LiFePO4‑specific charging solution—provided the installation is dry, ventilated, and the battery chemistry matches the charger’s LiFePO4 profile.
