Taking the Lipo plunge, need advice

[spaz163]

Up to this point I have been running NI-MH, but now that I have went with a 1/8 buggy I would like to loose some weight. The 14 cells I am running in it right now weigh it down terribly.

So below is a list of what I was thinking about going with and I would like any input on any of the products... especially the lipo packs. Any and all help is greatly appreciated.

Elite 4800mah 4s lipos from cheapbatterypacks.com (25c constant, 35c burst)
MRC 989 charger
Astro Flight Blinky balancer

I will be running the lipos in my 1/8 buggy which I have a Mtroniks Truck ESC and a Feigao 8XL motor. Also, if anyone has lipos or chargers that would be better for around the same price, feel free to recommend them. Thanks again.
