No, I don't have the lipo alarm, but I should get one.

Kenny, don't get the gy-401 gyro unless you have a different radio. It won't work with the stock Transmitter. The reason your ESC burned up is because the large batteries you added were awfully heavy. This caused the motor to turn slower and the blades to pitch greater with lots more amp draw. The ESC couldn't dissipate the heat so it spontaneously combusted. (Must have looked cool!)

If I were you, I'd go with the Pixie ESC's and get a gy-240 Gyro or equivelent and some Thunder Power 1320's. That will give you a heading hold gyro and about 10+ minutes of flying for each battery. The weight of the battery shouldn't exceed the OEM batts weight of about 110 grams. TP 1320s are 90 grams so thats just extra gravy.

The slower a motor turns, the more amp it draws until it completely stops. Then, its just a dead short. That's what the fuse is for, it blows incase the motor stops suddenly (blade strike) and you haven't throttled down quick enough.

Ok, I'll get off my high horse. (Just trying to save you another headache )
