I'm using one of these this year. We only have four batteries at present, so knowing the capabilities of each is critical. I have recorded measurements of all batteries at well-defined points. E.g. after each use in a testing session, after each charge session, after each idle period. I expect to use the information as evidence that we need more batteries for competition.

My only objection to the device so far is that it comes with a lanyard (around the neck) that doesn't split. Safety hazard in a mechanical environment.
