Fuel Gauge for PCB of 18.5V Li-Ion Battery Pack (#4480)

Note: This fuel gauge is not intend to be use as a very accurate reading of the battery pack's capacity. The battery level indication can vary by 5% depending on the capacity of the pack!

Features:

• Apply to PCB/PCM of 5 cells Li-ion / Polymer Li-ion 18.5V 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  < 14.8V  (must recharge battery)
  • 1 LED = pack voltage: 14.7-17.8V  (battery need recharging)
  • 2 LED = pack voltage: 17.7-18.6V
  • 3 LED = pack voltage: 18.5-19.7V
  • 4 LED = pack voltage: 19.6-20.2V
  • 5 LED = pack voltage: 20.2V or higher ( battery is fully charge)
