Intelligent Thermal & Management

The front panel integrates an advanced dual-color LED diagnostics system controlled by an internal MCU for real-time tracking of the smart battery charging profile curve:

• Solid Red (Standby): Power On / No Battery Detected.
• Blinking/Cycling Red to Green (Active): Safe execution of Pre-charge / CC / CV phases.
• Solid Green (Finished): Auto Cut-off active; battery at 100% capacity. Safe for long-term float connection.
• Flashing Alternately (Fault): System Error Latch (Output Short-circuit, Reversed Polarity, or Thermal Overload).
• DC Terminals as follwoing:
  

  Custom Charger Output Connector Options

  Phonix supports custom DC output connectors for battery chargers, allowing the charger to match your battery pack, BMS, charging port and end equipment.

  Common options include 5.5 × 2.1 mm and 5.5 × 2.5 mm DC barrel plugs, locking barrel connectors, Molex, JST, XLR (Cannon), GX aviation connectors, waterproof IP67/IP68 connectors, Anderson Powerpole, Anderson SB, SAE, XT30, XT60, XT90, DIN, Mini-DIN, USB-C and MC4 connectors.

  For OEM and ODM projects, we can also customize the connector type, pin configuration, polarity, cable length, wire gauge, overmolding, connector housing and terminal configuration according to your equipment requirements.

  Whether you need a compact barrel plug for a small appliance, a locking connector for industrial equipment, an XLR connector for an e-bike or mobility application, or a waterproof connector for outdoor and marine equipment, we can configure the charger output to your specification.
