Product Overview
The SPIDERWAY 54.8V 100A intelligent lead-acid battery charger is a high-performance charging device designed for electric forklifts, including models from Jungheinrich, TOYOTA and LiuGong. It uses intelligent charging technology to support a safe, efficient charging process while helping to extend battery life.
The charger is intended for 48V/200-500AH lead-acid battery packs and delivers an output of 54.8V/100A. It is suitable for high-power lead-acid batteries such as those used in electric forklifts.
Key Features
- Intelligent charging management: The embedded microprocessor runs a charging curve program automatically and adjusts charging parameters according to battery status to improve charging efficiency.
- High-efficiency charging: Charges automatically according to the battery charging characteristic curve. The charging mode is constant current → constant voltage reduction (equalizing voltage value) → trickle floating charge (automatic judgment conversion). This supports fast charging speed, high charging recovery efficiency, no need for manual supervision, long-term charging without overcharging danger, and helps ensure battery service life.
- Multiple safety protections: Includes input over-voltage and under-voltage, phase loss, internal overheating, output over-voltage and under-voltage, short circuit, reverse connection, and battery over-discharge protection.
- Fault code display: Shows fault codes such as output overcurrent E1, battery pack overvoltage E2, and battery pack undervoltage E3 for quick problem diagnosis.
- Data display: Displays charging voltage U, charging current A, charging time H, charging ampere-hour C, capacity setting value AH, and records charging data in real time.
