Introduction: This advanced 8-Channel Battery Tester is designed for precise and efficient battery testing, suitable for both professional and hobbyist use. It offers independent channel operation, real-time monitoring, and comprehensive testing modes to ensure accurate battery performance analysis.

Key Features:

• External Discharge Terminal: The blue segment at the upper end serves as the external discharge terminal, with a working indicator at the lower end for each channel.
• Real-Time Monitoring: Displays voltage and current curves, real-time voltage, and current measurements, utilizing a DC two-wire method for internal resistance measurement.
• Efficient Heat Dissipation: Features a U-shaped groove at the back combined with a PCB board and an active fan to create an effective heat dissipation channel.
• Compact Battery Holder: Designed for 18650 batteries, the compact holder is ideal for flat battery measurements.
• Independent Channels: Eight independent channels allow for unrelated, independent operation without mutual interference.
• Channel Synchronization: Supports synchronization of all 8 channels or individual parameter settings for each channel.
• Cycle Charging and Discharging: Supports one cycle of charging-discharging-charging in automatic mode.

Technical Specifications:

• Working Voltage: DC 5V 10A (power supply sold separately), overpressure protection to prevent machine damage.
• Power Supply Interface:
  • DC5.5 high-current interface
  • 5V positive and negative welding points
• Power Supply Reverse Protection: Includes reverse protection to prevent damage from incorrect power supply connections.
• Modes:
  • Automatic Mode: Charges to 4.2V, discharges according to stop voltage, and recharges to 4.2V.
  • Charging Mode: Charges to 4.2V, stops when the current is less than the stop current for 30 seconds.
  • Discharge Mode: Discharges until the load voltage is lower than the stop voltage for 10 seconds.
  • Activation Mode: For professional use, requires manual stop.
• Charging Current: Maximum 1A per channel, not adjustable.
• Charging Stop Voltage: Adjustable in 6 steps (3.7V to 4.2V).
• Recharge Stop Voltage: Adjustable in 13 steps (3.0V to 4.2V).
• End Current: Adjustable (100mA, 200mA, 300mA).
• Discharge Current: Maximum 1A per channel, not adjustable.
• Discharge Stop Voltage: Adjustable in 17 steps (2.0V to 3.6V).
• Standing Time: Adjustable from 1 to 5 minutes.
• Status Preview: Supports 8-channel status preview on one screen.
• Single-Channel Display: Supports detailed display and curve display for each channel.
• Internal Resistance Detection: Uses DC method for accurate measurement.

This 8-Channel Battery Tester is an essential tool for anyone needing precise and reliable battery testing capabilities.

Note:

• This product has undergone an upgrade, primarily involving a change in the battery box type. The latest version features a spring-loaded battery box, while the functionality of the product remains unchanged. Please note that both the new and previous versions are being shipped randomly. Customers may receive either version. We appreciate your understanding. If you have a strong preference, please consider this before placing your order.
