Alright, Well, you were using a failing battery, a Lipo at that, which is dangerous, it could catch fire. Wrapping it in the shemagh doesn't help it cool either, throw it away and buy another.
If you are tapping on semi auto, some times the gun will seize and no longer fire, it can be 'unlocked' by briefly switching to full-auto and firing a burst, then return to semi auto.
What spring are you trying to pull? What is your gear ratio? if the gear ratio is too low, your motor may not be strong enough to fully cycle once the battery is low.
I recommend purchasing a real motor, not something from vanguard, pick up a High Torque motor, not a high speed, and get some nice 18:1 gears.
Also, if you're playing at Vanguard, you should never full-auto, irregardless of your reasons, it is against the rules.
the lipo is brand new, and wrapping it in a shemag is the best thing to do in hot weather. the gun seizing isn't really the problem atm, no idea on gear ratio but pulling a 130 , i have a high powered motor here

oh, and the reason why i have a vangurdle motor is because they put one in when they repaired my tappet plate.
and according to airsoft gi, it would be 18.72:1 Source (

and at the all night donation game at vangurdle they had 1 full auto game.
i gotta dip out and go to work, if you really think its the battery, than take a look at my shopping cart

if there's anything else that might be a contributing factor please text 4806509257
