ICS Crane stock Batterys

[OZONE]

Hey guys,
I'm looking into getting my hands on an ICS M4 CQB and i had a question about the battery.
Its a crane stock Ver. and according to some websites you can only get a ICS crane stock battery in there, but some other sites say that it takes any crane stock battery.
I was wondering weather anyone knows which one of these is true, as i dont want to spend £40 on a specific battery if i could just use another, cheeper brand.
Sorry if this seams like a stupid question, or if something similar has been asked before but any help would be appreciated

Cheers
Sam

not 100% sure but i think they have a "special" cranestock with contacts in it that contact the battery, you could however just buy a different stock and a normal battery used for cheaper than £40 i imagine.
