a greeting

I would go for the icharger. It does more, and has a schweet screen!

I have a super duo 3 and I love it, good solid charger, not too big for all the power it has, but that I Charger does look pretty cool, no comment either way on the I Charger as I have never used one, nor do I know anyone who has one...

I don't know what kind of racing your going to be doing, but if I was going to do on road only, I would lean towards the LRP Pulsar touch, but I run both on and off and I have both!!!

I just changed my on road charger from a GFX Turbo 35 to the Pulsar Touch.
Off Road it is a Super Duo 3, 2 - 4s packs charging and balancing at 10 amps at the same time (capable of 20 amps each) is pretty sweet!

Revolectrix 10xp seems like a solid performer. I have the same Hyperion as you and the 10xp is going to be my next charger.

The Cellpro 10xp is not a true "duo" charger. From what I understand/read it basically wires the two packs in series to do the charging.

The Junsi 308/4010 Duo chargers and the upcoming FMA PL8 Duo charger are the top of the line duo chargers currently. The Junsi models are a bit more refined in their display and input. The FMA chargers are by far the most reliable.

I think you are correct after I reread the product description.

I just got a 308 duo and think it's a great charger. For the power it has and all it can do I'm was surprised at how small it is. Also they have great tech support.
