Features:

  • Discharge Current: Supports continuous discharge up to 3A, ideal for low-power applications.
  • Low Self-Consumption: Minimal power drain when idle, ≤3μA per cell.
  • Charging Parameters: Charging voltage set at 3.7V, with 3A charging current.
  • Overcharge Protection: Activates at 3.7 ± 0.05V with an integrated delay mechanism and releases at the same voltage.
  • Over-discharge Protection: Triggers between 2.0V–2.1V with a 100ms delay and releases at 2.3 ± 1V.

Specifications:

  • Rated Discharge Current: 3A
  • Self-consumption: ≤3μA
  • Charging Voltage: 3.7V
  • Charging Current: 3A
  • Overcharge Detection Voltage: 3.7 ± 0.05V
  • Overcharge Protection Delay: Instantaneous with voltage threshold
  • Overcharge Release Voltage: 3.7 ± 0.05V
  • Over-discharge Detection Voltage: 2.0–2.1V
  • Over-discharge Detection Delay: 100ms
  • Over-discharge Release Voltage: 2.3 ± 1V

Installation Notes:

  1. Battery Matching: Ensure all cells are matched — voltage difference ≤0.05V, internal resistance ≤5mΩ, and capacity tolerance ≤30mAh.
  2. Wiring Order: Connect cells in parallel first, then series. Avoid using screws that could damage components.
  3. Old Battery Usage: Only use if the battery is confirmed to be in good condition.
  4. Voltage Checking: Use a multimeter to ensure voltage consistency across cells to avoid issues like rapid discharge or improper charging.
