Features

  • Apply to PCB/PCM of 2 cells Li-ion / Polymer Li-ion 7.4V battery pack.
  • No external power is need
  • Can connect directly to pcb/pcm via special connector on board or connect directly to output of battery pack
  • 5 LEDs display battery pack's voltage. The voltage listed below is base on battery during discharge. (The actual voltage might vary for LED 2-4 during charging.) 
    • 1 LED Flashing = pack voltage  < 5.5V  (must recharge battery)
    • 1 LED = pack voltage: 5.4-6.8V  (battery need recharging)
    • 2 LED = pack voltage: 6.7-7.3V
    • 3 LED = pack voltage: 7.2-7.7V
    • 4 LED = pack voltage: 7.6-7.8V
    • 5 LED = pack voltage: 8.0V or higher ( battery is fully charge)
