I got my RX2 setup yesterday and put it through its paces. I replaced a ton of wiring, power supply, and 2 chargers with it.
I so far really like it, but I am curious about charging speeds. The "Quick Charge" charges as fast as my Pulsar 3 Comps did... if not faster. The Smart Charge takes roughly 30 - 40% longer than the Pulsar's did though. To top off a 2500mAh charge on a 1S pack I had took ~ 45minutes. That said, it only took 49 to top off 3800maH on the same pack so obviously the first part and the bulk of the charge is fast, then the "finishing" takes a while.
I have a question - for battery life and health of the battery - is Smart, Charge, or Quick Charge better? Wondering for practice runs and such. Because the manual somewhat says that the pulsed charge it does is bad for cell life. or maybe that was just one of the many Engrish translation issues in the manual?
Also - no way to mute the charger, not an issue, but it would be nice. I do like the short beeps though when its done.
Overall, this is an awesome charger. I was charging 2 7.4 packs, one at 10A and one at 15A and the charger never broke a sweat, barely got warm.
This is the new hotness:
That replaced all this:
Also attached is a pic of an LRP Pulsar for size comparison. As you can see, from the side, they are almost he exact same size.
