    bought this battery to try in a 1:10 rc truck, works fantastic! I got an approximate 20-30% performance gain out of 1:10 RC volano truck, just from switching to a lipo battery.

    Its cheap and about 3700 mAH which is pretty sweet for 22 dollahs! build quality is decent, connectors and handle currents over 20 ampers nicely have yet to find any major flaws Not quite 4000 but close enough takes long to arrive One of the cheapest "4000" mAh lipos you can get. I'm of... Read more
