Ok, battery situation figured out 100%
I remembered i actually had a couple of those 8.4v Ni-Mh stick batteries, from NZ.
The snow wolf was built to take these.
Sure enough, it fits in the semi circle groove perfectly, no rattling, and the short lead has enough room to connect and tuck inside…
These batteries are several years old, and may not be in the best condition.
I hooked it up to my (newer) mp-40 8.4v Ni-Mh, and got these numbers…
So, ladies and gents, there’s your solution…
8.4v is safe ( it was built for these), fits perfectly (it was built for these) and has decent performance for a smaller mag.
Remember, short controlled bursts…
These should be available in Aust somewhere, or ebay.
The only downside is the charging…the one lead does it all… charging input and gearbox output.
The MP-40 included a ‘Blind’ charger…no lights, no indications, just plug it in and the battery and the charger slowly get warm. Leave it for 2hrs or so.
Stick with that, or get a smart charger, they wont be that expensive.
Of course, the Nano 7.4 lipo just fits, and is a lot lighter.
I’ll probably go for a 11.1v upgrade in the fullness of time, just because i like 1500 r/min from time to time…!!

Battery…Sorted…!!
