TF7 (MP7) battery mod
 

i seem to be having problems with my girlfriends tf7. i charged the battery for about two hours and it will cycle on full auto for about 5 seconds then die.

i have heard however of a battery mod that would put the battery outside the shell of the gun instead of inside the front of it. anybody have any hints or guides on how to do this?

To do this mod you would require to purchase the adapter.
Once you have aquired the adapter you can look into a few different options of housing the battery externally. I believe company called nine ball makes the external adapter your looking for.

thanks TS, i'll look into it.

Smokeys makes one as does Nineball

From there it's a matter of choosing the right battery, a mounting solution and connectors.
