Battery Batch

The echo 1 peq 2 battery box is a mock laser unit which lets you house a higher capacity battery on the exterior of your gun while still maintaining a realistic look. The battery for this is a 9.6v 1400mah battery pack. The normal M4 or M733 holds only a 9.6v 1200mah battery pack. I suggest buying a crane stock (not the ECHO 1 crane stock upgrade, and actual crane stock) if you have the money (crane stocks are expensive) so you can house the crane stock 9.6v 3300mah battery. I hope shorty’s replaces the 3300mah cells with 4200mah cells.
