Fuel Gauge for 20S (24V) NiMH/Nicd Protection Circuit Board (#4613)

Note: This fuel gauge is not intended to be used 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 20 cells Nimh/Nicd 24V battery pack.
• No external power is needed
• 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 based on battery during discharge. (The actual voltage might vary for LED 2-4 during charging.) 
• The following data is tested under 25ºC
• No LED on = Pack Voltage ≤ 20V±1V, must recharge battery
• 1 LED Red = pack voltage: 20V±1V to 22V±1V  (battery need recharging)
• 1 LED Red, 1 LED Green = pack voltage: 22V±1V to 24V±1V
• 1 LED Red, 2 LED Green = pack voltage: 24V±1V to 26V±1V
• 1 LED Red, 2 LED Green = pack voltage: 26V±1V to 28V±1V
• 1 LED Red, 4 LED Green = pack voltage: 28V±1V ( battery is fully charge)

Specifications

• Power consumption: Max 2mA (at Idle - no LED on)
