Custom Batteries for M4
 

Hi guys! I am new to airsoft, so I dont know what type of my gun ( plz tell me which one :p ). Because I bought from a guy, he already modified it. The problem is his batteries was lost, so I have to buy new ones, and it is a problem. I tried to solder the wires to the batteries but it seems the little metal from both heads broke off. So I wonder if it's ok for me to glue the wire to the batteries. If not could you help me on how to make the wire stick to the battery. Here is my gun, cross type, and battery.

Batteries are cheap now days, just buy a new one. If the stock is a G&P, this will fit: Linky. If not, you can also try something like this: Linky.

looks like this is the large type stock subC i think the cells are so ya the first link should fit stock may not fully collapse. a nunchck bat will for sure fit and they are smaller and lighter to cary spare, i put some tape on em so they fit snug

well, I just bought another set 1600mah. However, I still like this one cause it's 4200mah, but the shop that I visited only sell that particular separated like I shown you in the picture.( Did I mentioned that both 1600mah and 4200mah are 9.6V?) And how long will a 1600 last with a newbie like me? How do you disassemble a SR-16 M4 (just discovered it on my gun)?
