48V 120W Lithium Battery Charger

A high-quality 48V 120W lithium battery charger is offered by the Chinese manufacturer Starwell. It is specifically designed for light electric vehicles. During the constant-current phase, it delivers a stable output of 120W; upon transitioning to the constant-voltage phase, it precisely controls the upper voltage limit. Once the battery is fully charged, the unit automatically cuts off the output, effectively preventing the risk of overcharging.
Features:
♦Universal AC input/Full range(up to 264VAC)
♦Protection: Short circuit/Overload/Over voltage/Over temperature
♦Built in PFC function, PF>0.95
♦Cooling by free air convection
♦Suitable for all kinds of LED lightings, and moving sign applications.
♦Built-in constant current limiting circuit (C.C.+C.V.mode);
♦Compliance to worldwide safety regulations for LED lightings

Product Details

As a professional charger manufacturer in China, Starwell Factory's 48V 120W Lithium Battery Charger is specifically designed for 48V lithium-ion battery packs. It employs an intelligent Constant Current/Constant Voltage (CC/CV) charging mode; after rapidly charging at a constant power of 120W, it automatically transitions to the constant voltage phase to prevent overcharging and extend battery lifespan.

Equipped with a built-in microcomputer management chip, the charger monitors battery voltage and temperature fluctuations in real time. It operates in conjunction with the Battery Management System (BMS) to ensure that the charging process remains safe and controllable, thereby fully meeting the rigorous requirements of lithium-ion battery packs.

What is a 48V 120W Lithium Battery Charger?

The 48V 120W Lithium Battery Charger is an intelligent charging solution meticulously engineered for 48V lithium-ion battery packs. Designed with precision and safety as its core principles, this charger delivers reliable performance for a wide range of electric vehicles, including e-bikes, scooters, and light-duty mobility devices.

At the heart of this charger lies its intelligent charging control system, which utilizes a constant current and constant voltage (CC/CV) charging mode. This advanced methodology ensures the battery is charged efficiently and safely: the constant current phase delivers a steady 120W of power for rapid charging, while the constant voltage phase gradually reduces the current to prevent overcharging, thereby extending the overall lifespan of your lithium battery pack.

The charger is specifically programmed to precisely match the charging curve of 48V lithium battery packs. Unlike generic chargers, this device communicates with the battery’s internal management system (BMS) to ensure the voltage and current are perfectly regulated at every stage of the charging cycle. This meticulous calibration guarantees a full, balanced charge without risking damage to the battery cells.

Safety is paramount in the design of this unit. It is equipped with multiple safety protections to safeguard both the user and the equipment. Built-in safeguards include protection against short circuits, reverse polarity (to prevent damage from incorrect cable connection), overcurrent, and overheating. These features work together to provide a worry-free charging experience, automatically cutting off power if an anomaly is detected.

Despite its robust performance, the charger features a compact and lightweight design that makes it easy to carry. Whether you need a charger for home, the office, or to keep in your backpack for on-the-go top-ups, its portability ensures you always have access to safe and reliable power. Durable and user-friendly, this 48V charger is the ideal power companion for maintaining the health and performance of your lithium-ion batteries.
