Razor E300 Scooter Gets Big Battery Power Upgrade - Scooter Episode 3

Parts links below!
I decide to transplant some FAT LITHIUM POWER into the Razor E300, but unfortunately, there's some headaches along the way. We're not done yet... we need to toughen this beast up across the board.
Parts sourced from Hobbyking, though one day I'd like to try subbing in a dedicated e-Bike pack instead, you know? LiPos are great. We love power after all!
