I don't think anyone has tried it yet. It doesn't get released until Feb 22nd.
But yes I have been eyeing this one for sure. The specs look awesome. I love the fact that it gives you a readout of the internal resistance of each cell and a battery quality/health check. Thats a feature that i haven't seen before. Finally a real way to tell how good the low cost lipos are vs the high dollar packs. Just that feature alone my mean it makes it into the stable for me.
