I have a TM MP7 and it is wired to deans connectors and I have a 7.4v 900mah (25c if that makes any difference) wired to deans also. I can't seem to plug in the battery and put it in the battery space, I have been able to do it once (I put the battery in and then connected the connectors) but I wasn't able to put the front piece back on. I am thinking of either getting a PEQ box and feeding the wires from gun through the holes in the body and then jus connecting them, or seeing if I can somehow get the connectors outside of the gun while keeping the battery inside. Can you think of anything else I could do? And what do you think of the two things I am thinking about? Thanks for any help.
