Battery recommendation with these upgrades

Recently purchased a second hand gun with a few upgrades. New to upgraded guns so wondering what battery should I be using to make the most of these upgrades but also staying reliable. 

VFC E series m4 AEG

-[SIZE=17pt]promtheous internals including gears and piston.[/SIZE]

[SIZE=17pt]-TM EG30000 high speed motor installed -ICS hopup[/SIZE]

Cheers

pic of gun ???

front wired in handguard or Peq box baby M4

or

rear wired in crane stock

7.4v lipo 20c or 25c is my first guess

I'm guessing s/hand ???

I love it when seller say TM motor or stuff like that...

(don't make it a bloody Tokyo Marui)

Prommy gears - probably coz old VFC set had a spring on spur/sector (daft idea)

find a pic on google images, right click COPY & paste it in here/reply

or a link would help to suss out exact model if poss

PS - welcome to the forum

YOUR RESPONSIBILITY TO ENSURE ANY BATTERY YOU BUY FITS !!!!

DO NOT SUE ME IF YOU BUY A BATTERY THAT DOESN'T FIT

YOU CHECK YOURSELF THEN YOU ARE RESPONSIBLE !!!!
