🔌 Flexible Connector Options
AC plug is optional (various country standards). The length and wire diameter of the AC cable are optional; if no special requirements, appropriate specs will be matched. DC plug is also optional — customers may supply their own connectors (as long as they are commercially available).
Customization: The length and wire diameter of both AC and DC cables are flexible. Based on output current and application, we provide suitable wiring. Contact us for specialized harnesses or waterproof connector integrations.
📈 Smart Charging via CANBUS & RS485
The integrated CANBUS/RS485 interface enables intelligent charging strategies: remote start/stop, real-time voltage/current monitoring, battery temperature compensation, and automatic charging curve selection. Ideal for fleet management, automated guided vehicles (AGVs), electric boats, and industrial lithium battery banks. The charger can be seamlessly integrated into existing BMS (Battery Management System) for enhanced safety and cycle life.
