14.6V 4A (4000mA) 58.4W 4S LiFePO4 Battery Charger with Anderson Torberry DC Connector

Product Overview

The Guangdong QINX Technology Co., Ltd. 14.6V 4A 58.4W LiFePO4 battery charger is designed for 4S LiFePO4 battery packs requiring a regulated 14.6V charging output. With a 4A charging current and 58.4W rated output power, this desktop charger provides a practical charging solution for electric golf trolleys and other compatible battery-powered equipment.

The charger uses a universal 100–240VAC input and is designed for international B2B applications. Its Anderson Torberry DC connector provides a practical connection option for compatible battery systems, while the DC cable can be supplied at 1.2m or customized according to project requirements.

For manufacturers and distributors sourcing standard or customized charging solutions, Guangdong QINX offers a range of LiFePO4 battery chargers covering different charging voltages, currents, power levels, battery configurations and connector requirements. This allows customers to select a standard charging platform or discuss a modified specification for a particular battery system.

The 4S configuration is important because the 14.6V charging voltage is intended for a four-cell LiFePO4 battery pack. Before selecting the charger, customers should confirm the battery chemistry, series configuration, required charging current, BMS requirements and connector compatibility.

Technical Specifications

Energy Efficiency

The charger is designed around a Level VI energy-efficiency requirement, helping reduce unnecessary energy consumption during normal operation and standby conditions.

The 58.4W output rating does not fall within the automatic Active PFC threshold defined for higher-power products in the QINX product-page specification rules. Therefore, Active PFC is not presented as a fixed specification for this model unless the specific product configuration is separately confirmed.

Applications

This charger is primarily suited to compatible 4S LiFePO4 battery systems used in electric golf trolleys. Golf trolley manufacturers and distributors can use the 14.6V charging platform where the battery pack, BMS and connector configuration are compatible.

The product can also be considered for other compatible LiFePO4 battery-powered equipment where the required charging voltage is 14.6V and the charging current is 4A.

For broader battery-powered applications, Guangdong QINX provides power solutions for battery-powered equipment according to battery configuration, charging requirements, connector configuration and operating environment.

Connector Options

This model is specified with an Anderson Torberry DC connector for compatible golf trolley and battery-pack connections.
