Industrial Applications & Technical Support

Customizable Enclosure & Thermal Solutions: To fully match your specific working environments and eliminate technical uncertainty, this 205.8W industrial charger supports Tailored System Configurations. Depending on your project requirements, it can be customized with either Natural Convection Cooling (Fanless Design) for silent, zero-maintenance dust-free operations, or an Intelligent Cooling Fan to optimize heat dissipation during continuous high-current loads. Wrapped in a compact aluminum chassis (178*80*46MM), it delivers a flexible, robust power backbone.

Application Versatility & Compliance: Our engineering team can fine-tune this power profile for high-demand, specialized sectors. This SKU is perfectly suited as a base platform for customization in:

• Light Electric Mobility: Reliable power management and steady 7A current delivery for commercial e-bikes, logistics delivery scooters, and warehouse micro-mobility.
• Industrial LED & Automation Tools: Sealed, fanless configuration option makes it ideal for dust-prone factory floors, site lighting, and automated field equipment.
• Your Specialized Applications: Facing a unique or unlisted application? We regularly modify enclosure types, connector styles, and internal protections based entirely on your target blueprints.

Battery Compatibility & OEM/ODM Engineering: This hardware is standardly calibrated for 7S 25.9V nominal lithium-ion battery packs. However, its exact charging profile, custom cut-off voltages, and intelligent protection parameters are completely customizable.

Note: If your system involves multi-pack configurations, specific CAN-bus/SMBus protocols, or unconfirmed hardware requirements, please consult our engineering department for a tailor-made OEM/ODM consultation before placing your bulk order.
