Operating Instructions

Charging the Battery

The included 58.4V 18A charger supports fast charging. It can charge the battery from 60% to 100% in approximately 2 hours. A full charge from 0% takes about 5.5 hours.

• Connect all cables as described in the Setup section.
• Plug the charger into a power outlet.
• Monitor the charger indication lights:
  • Green Light On: Fully Charged (100%)
  • Red Light Fast Flash: Precharging Stage (0%-10%)
  • Red Light Slowly Flash: Fast Charging Stage (10%-99%)
• Always charge the battery promptly when its charge level drops below 5% (46V).

Monitoring Battery Status

The kit includes an LCD Bluetooth monitor and supports a mobile application for real-time battery status monitoring.

• LCD Bluetooth Display: This display shows battery voltage, charge level, discharge current, temperature, and the status of each cell. The settings page allows control over charging/discharging switches, screen-off time, and power off/screen-off functions.
• Mobile APP: Download the Elefast APP, register, and log in. Connect to the battery's Bluetooth or the display's Bluetooth.
• Important Note: Only one Bluetooth device (either the LCD display or the mobile app) can be connected to the battery's Bluetooth at a time. If a Bluetooth signal cannot be found, disconnect any other connected device.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your Elefast lithium battery.

• Charging Habits: After using the battery, especially if the charge is low, charge it promptly. Turn off headlights and the display screen, and remove the key when not in use to prevent unnecessary discharge.
• Deep Cycle Life: The battery is designed for a long lifespan of up to 8000 cycles.
• Temperature Management:
  • Charging Temperature: Maintain between 32°F (0°C) and 122°F (50°C). The BMS will automatically cut off charging if the temperature is below 32°F.
  • Discharging Temperature: Maintain between -4°F (-20°C) and 140°F (60°C). The BMS will stop discharging if the temperature is below -4°F.
  • Storage Temperature: For optimal long-term storage, keep the battery at or above 32°F (0°C).
• Cleaning: Keep the battery and terminals clean and free from debris.

Troubleshooting

The Elefast battery features a built-in 200A Smart BMS (Battery Management System) to protect against various issues. If you encounter problems, refer to the following information.

BMS Protections

The Smart BMS automatically protects the battery from:

• Overcharging
• Over-discharging
• Overloading
• High Temperature
• Short Circuit

The BMS will automatically cut off charging if the battery temperature is lower than -4°F or lower than 32°F, and stop discharging if the temperature is below -4°F.

Charger Fault Analysis

If the charger indicator shows a Red/Green Light Flash, it indicates a fault. This could be due to:

• Standby/Short Circuit: Check wiring connections.
• Low-Voltage Protection: May require engineer settings.
• Over-Voltage Protection: Stop charging immediately.

Bluetooth Connection Issues

If you cannot connect to the battery via Bluetooth (either display or app), ensure that only one device is attempting to connect at a time. Disconnect any previously connected phone app or display before trying again.
