I've used the bnb for the last couple years. It's true it can only handle 30v, but the software adjusts the voltage to show 2x which is fairly accurate. It's a nice unit and works well. I just got the eagle tree and have been using it lately. Has a few more features then the bnb, like a calibration feature, better exporting of graphs, but they're both comparable. bnb is coming out with a new higher voltage model, not sure what all the improvements will be. As they are now, I'd go with the eagle tree.



I'll add if your running a 10s pack which is permanently configured as 10s you can only use the micro logger. If your running 2 packs harnessed together then you can use either. The bnb unit came before there were 10s chargers and 10s packs.
