Sure, some way to get battery data to AQ would be great. It could be used to calculate flight time, transmitted to GCS/OSD, logged, etc. Current is vital of course, and individual cell voltages would be nice. I'd like a way to hook up multiple units to one 1W port, or some way to monitor multiple battery packs (I use individual battery leads to the PDB, not a splitter, so there's no single point to measure current from).
Speaking of battery testing, is there a product out there to do a simple/quick load test on a LiPo? Something at a higher rate than a typical charger/discharger can do, and cheaper. Used those for car batteries back in the day... put a high load on it for a short time and see how much the voltage sags. Not a very sophisticated device... just a variable load and a voltmeter.
