Hi all i have an m4 with all stock internals motor, gears, hop up etc the battery that came with it has (NI-MH 2/3A 1100mAh HP 8.4V) written on it.
Am just wondering what battery i could upgrade to that wud be better and last longer etc ??
and if u cud recomend a place were i could get them wud be very much appreciated
would depend on the make of the gun most m4s as standerd can go up to 9.6 but you would need to share the brand and how old it is to know for sure
it has colt written on the gun if thats the make and its less than a year old if that helps
it sounds like you have an 8.4v Nimh 'mini' type battery (so called because of the size/type of the connector; mini-tamyia) judging by the mAh rating you've given.
Assuming it's a garden variety 8.4v mini (2 rows of three battery cells with one across the bottom), you can easily pick up the same type of battery with a higher mAh rating, which will give you more shots at a minimum improvement; e.g. 1200 mAh, 1500mAh, etc.
I use Component-Shop for my batteries (but then again my better half & I also use all sorts), but any airsoft shop should be able provide 8.4v or 8.4v mini battery types of varying mAh sizes.
