OK UltraC, since you appear to be new to this, you should probably start small and do some basic mods before moving into LiPos and rewiring your blaster.

The easiest, safest, most cost effective mod for the Demo is a simple battery upgrade. You'll need two 14500 IMR batteries. Make sure they are at least 750mAh or higher, preferably much higher. In my experience 2000mAh seems just right.

Next you'll need two dummy batteries. I've been using Ultra Cells, but there are a lot of places to get dummies on Amazon and eBay. Just throw the two IMRs and two dummy batteries in your Demo and go for it.

This combo will give you a nice boost, and best of all, you won't have to worry about the motors. Don't be tempted to throw another IMR into it, because the thermistors will kick in and shut down your blaster after a few seconds.

Beyond that, there are flywheel upgrades, motor upgrades, wiring upgrades, and finally serious battery upgrades. But start small my friend.
