I've had the rare privilege to try odysseys little black box, and I can tell you it's amazing!
You get a full download of battery status: voltage and capacity for each of the 93 cells, total voltage, various temperatures, statistical analysis, all in a few seconds at the stroke of a key (to get the same data via DAS takes 5min or more, if you know what you're doing). Plus this beats DAS in price by 10x compared to the Chinese knock-off or by > 100x compared to the real thing.
And this is just the beginning! Odyssey and a few geeks in Germany are working on expanding the capabilities and adding features. And you can help, too: code is available at github.
This is a must-have for anyone who wants to learn more about what goes on under the hood (err ... bottom). It beats even the regen-paddles by miles in terms of value-for-money!
A big Thank You to Odyssey for leading the way!
Now go build your own! Let's get some more brains in on this and see what we can do...
