"I was in a *serious bind, so I went to the pros.
I needed a very compact, very powerful battery to fit inside the back of the suppressor on my VSS Vintorez rifle. With a MOSFET and wiring harness taking up most of my dust cover compartment, this was my last option for placement.
The VB-Power cells are exceptional quality and the wiring is tough like a Belorussian infantryman. This pack turns over 24.5 r/sec in a gun making 393FPS with an airbrake and a short barrel, and has thusfar been the tiniest little thing I could find.
This would be a great option to fit inside your MOE or G36C for some nasty power.
Low C-rating means that while a MOSFET is still preferred, it won't outright fry stock trigger contacts. Big guts in a little pack means that you should still have well-shimmed, high-quality gears and a well adjusted high-end motor if you want to avoid damage.
You will not be disappointed. "
