ok I bought an m4 second hand and i saw it work perfectly with an 8.4v 600mah battery.
I bought an 8.4v 3800mah battery as my research told me this would be fine but the connections differred between the gun and the battery so after a trip to maplins I changed the connector on the gun to fit...
hey
basically, just bought a second hand M4, really good nick, with a couple of mags...
but no battery.
they guy was using an 8.4 600mah battery, but says it may be able to take more power.
how do i know the maximum power it can take?
thanks :)
