Yes.
Many companies make powerful batteries. Li-Po gives your gun the fastest rate of fire and is a lot smaller. If you are going to have a more powerful battery, you should see if you need to upgrade the motor and or put some metal gears so they don't strip out as fast as plastic.
You can but the motor may not run, however you will not burn the motor.
In any electrical device, feeding an amount of voltage which is greater than what it was intended to use is prone to causing damage to it. If your airsoft gun came with a 1.2v battery, it was designed to be fed from a 1.2v current, and placing an 8.4v battery in it will cause it to feed from a current seven times greater than what it was intended to use. This creates a risk of overloading the motor, which, for electric motors, typically causes it to burn out. This creates heat, naturally, which can also have the effect of melting down the materials used to manufacture your airsoft gun (as far as I know, they're mostly made of plastics), which will render it not only inoperable, but also damage it beyond repair. So, the short answer would be no, and you should use only the recommended battery for your airsoft gun.
maybe the motor is burn..... maybe the motor is burn..... maybe the motor is burn..... maybe the motor is burn.....
This blender has a 1.5 horsepower heavy duty motor it should be able to handle a very thick mix.
you can but if you do, you will/might: A) kill the motor,B)overload your 18 volt power supply, and C) maybe short a breaker if your power supply is also an ac to dc converter
why would my starter wire burn, going from starter to battery
Yes, if you short the battery out it can explode and burn you.
A battery burns out by leaving the device that contains the battery on to long of a period of time.
yes
Leaking battery acid can burn your skin. Im not sure if that qualifies as a rash, the correct term is chemical burn.
Its eruption as the first powerful is blast burn.
Yes, it will burn.
