    ok maybe someone can help, when i put a fully charged battery in after a couple of rounds it starts to slow down as if the battery is going dead, but when i put the battery in a different gun it lasts the whole day, this happens the M16 with all my batteries??

    The motor could be drawing too much current, I had to put a fairly beefy spring in my M4 to get the fps up and I only got a few rounds through it.
    What spring is in it?

    Is the fuse still in or have you removed/bypassed it?
    The reason I ask is (imo) if the motor is drawing that much current - it would almost certianly blow your fuse and probably fry your wiring too.

    it was downgraded a while back not sure what spring chuck put in it but this has only started happening in the last 2 weeks, i will change the motor and see if that solves it

    It depends on the fuse installed, some AEG's have fairly high 20-25amp fuses installed in them, I wouldn't go much higher than 16amps personally.

    could be a number of reasons why the battery is not lasting as long

    depending on how the downgrade was done could be an explenation, if its a drilled cylinder your still pulling a 100m/s + spring, but if the downgrade was a spring change this is not an issue

    the shimming could be wrong on the gears causing the motor to work harder to turn over meaning its drawing more from the battery

    motor height could be wrong again this could lead to the motor working to hard and drawing more from the battery if the motor height is too height

    or motor could just be faulty and drawing to much from the motor

    as others have said a few starting points

    The gearbox could be shimmed to tight, or it's just becuase it's a sportsline :P

    so its defiantly a issue with the gearbox on the sportline then, you would have to checking motor height shimming wiring and general component fit within the shell, i had an aeg where the piston rails where slightly two large meaning undue friction, motor had to work harder and battery did not last as long

    Is the battery getting warm when ya try to fire it too?
    I would agree with the lads, it sounds like the shims are causing it to bind and work harder than it needs too, this usually follows with the battery getting hotter. the fuse should blow but that really depends on the fuses rating etc. :)

    no nothing like that, no heat nothing its just as if the battery goes dead but in a different gun its fine again??

    Could be faulty connections somewhere down the line.

    Here's one to try, this happened to my DE UMP. Check the connectors from the gun that connect to the battery. What happened to me was the black wire had slipped and wasn't all the way in the plastic connection and so the battery was at best only tipping off the wire and when you fire, gearbox jumps, wire slips more, no power. Hope that makes sense and helps.

    Keegan's made a good point it could be the battery connector on thats causing the problem. As for the spring it was a 90 (it was over the limit with the stock spring for some reason).
