This isn't going into my last power thread as batteries aren't an unusual or uncommon form of power storage, quite the opposite!
Reading about a more efficient battery that could come in at half the weight of current models with a similar output reminds me of the Tech Stages in BBB2. I've only used the changes in stages of tech available to players a few times, mainly when it's moved a plot point along or has been important to exposition during a session. Additionally, I normally handwave battery power unless it's important to the plot in the scenario.
Who uses either of those things? Tech stages showing improvement in items that PCs or their antagonists have, and power held in batteries...
