Battery for PVS-2

[m4carbine]

The best bet is 2 ea. 1CR2 Lithium batteries stacked parallel in a fake battery body made from Delrin rod.

Its 2.1" long X 1.375 in dia. with a .605 dia. hole.

I have a PVS-1, PVS-2 and a British L1A7 sight that I use these in with no problem. The up side is that this set up has about 10 times more life than the original Mercury cells.

The Batt spec voltage is 7.5 but they draw down to about 6 volts right away. The great thing about the Lipo batteries it there is not a big voltage drop like Carbon or Mercury batteries, they run at about 6V almost until they die.
