My Laser Blinky Notes
P. McGill 27Apr21

* Bulkhead connector on battery housing is probably Seacon VSG-4-BCL, with a VMG-4-FS mating connector on the cable.

* The laser connector whips are Impulse IE55W-1002-CCP. Pin 1 is ground, pin 2 is 6.5-28VDC input. Viewing the face of the CCP with index flat up, pin 1 is on left, pin 2 is on right. Pin 1 is white wire, pin 2 is black wire.

Pin 1 - left - white - ground
Pin 2 - right - black - 6.5-28VDC

* Lasers draw 21 mA at 9 V. If lasers are blinking with 50% duty cycle, then 2 lasers consume an average of 21 mA.

* Blinky circuit draws an average of 11 mA when battery is connected but no lasers are plugged in.

* According to the Duracell MN1604 datasheet, a 9 V battery will last about 5.5 hours at 0 degC with a 50 mA load down to 6.5 V, so it's about 275 mAh. With a 21 mA + 11 mA = 32 mA load, this would last about 275 mAh / 32 mA = 8.6 hours.
