Hi guys

I am new to electric. I have been flying nitro for couple of years.
I just ordered an electric slow flyer last week.
I need a lipo charger for the field and i am about to order the [link=http://www.electrifly.com/chargers/gpmm3010.html]Electrifly Polycharge[/link]
My question is : Do i need to order a [link=http://www.electrifly.com/chargers/gpmm3160.html]Lipo Cell Balancer[/link] with this one or it's built in ?
This is going to be used in the field, gym during the winter, i will eventually buy a good charger like the Triton 2 EQ for my home.

Thanks for your help
