Don't get Lipo until you truly understand the risks and benefits.
An overcharged lipo can explode.
a lipo left in the sun, or in a vehicle, or anywhere it can heat up can explode violently.
theres a picture floating around somewhere of the damage done to a vehicle that had a lipo explode inside, it literally blew the cab of the vehicle to pieces.
best to do is pick up a NiMH battery, and a smart charger.
