Description

Blinker Board - 3 amp

Protects tool batteries from over discharge.

Max Amps: 3 (if you need to power something more than 3 amps, use a relay)

Compatible with: DeWalt, Milwaukee and Makita 12/18/20 volt batteries. 

These are called “blinker boards” because they blink (pulse) the power once the battery reaches low voltage. “Blinking” refers to the output power being turned on and off rapidly, there are no actual lights on the board that blink. However, when used to power lights, the lights will blink.

If you do not want the blink feature, you can disable it by bridging SP2. With SP2 bridged, the board will shut off immediately without blinking (when the battery is low).

How it works:

The board starts blinking (or shuts off if SP2 is bridged) at approximately 15.8 volts for 18/20 volt batteries and 11.2 volts for 12-volt batteries.

The power blinks 2 times>stays on for (approximately) 4.25 minutes>blinks 5 times>stays on for 1 minute>then shuts off.

There is an auto-select feature that checks for 12V or 18/20V system and selects its mode accordingly.

Connections:

  • Positive wire from battery goes to P1
  • Negative wire from battery goes to P3
  • P4 goes to minus (negative) on whatever it is you are powering
  • P2 goes to plus (positive) on whatever it is you are powering

The boards have reverse polarity protection on the input side only.

Please Note: It is very important that you do not connect/short the positive and negative on the output side as this will burn out the board.

Disconnect your battery from the Blinker Board before connecting it to your application.

The boards were originally designed to power buggy lights. The blinking feature is to blink the lights and warn the user that the batteries need changed.
