I held the 4PX in my hand at the Hobby Shop on Sunday and oh my god! I am getting this thing!

Anyways a question for the Life Battery. Protek shown below. I don't right now have Life capable charger as I have the LRP Pulsar 3 and older Turbo 35 GFX.

So to get something low cost with this capability what is good way to charge this? I only see Life batts as this and receiver pwr pack for Nitro cars.

Also do you charge in the Futaba connector or Balance connector?
