PEQ Battery Boxes, Where To find?

[L9OBL]

I recently built a gun and wired it to be either front AND rear wired, so i'm not limited to buffer tube batteries or handguard mini batteries or those PEQ battery box batteries (you know the special ones dexigned for certain PEQ ll batery boxes) but I was wondering if anyone knew where to find a quality PEQ battery box with a green laser and flashlight that ISN'T constantly soldout I found one but it uses a special battery and the charger is european 220 volt. so do you know where to find them (for under 100$) i've seen em but they're always soldout or if not where can i find a european to north american style plug adapter cause all i can find is N.A. to EU.
