Why so many every year? As long as you take care of them during the off-season, they should be fine for many seasons of use. My team still keeps around a couple of 2011 batteries because they actually perform just as well as the batteries we got this year.

To my knowledge, the lowest our DS has ever read in-match was 5V during a brutal pushing match. It is very important to know how your batteries perform at low levels.

Our team rule is one match per battery per day. We put a freshly topped off battery in the bot at the start of every match and don't use it again that day if we can avoid it.

We do our best to avoid using the same battery more than once a day. Our battery box holds 12 batteries and uses a raspberry pi to automatically cycle through the batteries and charge 3 at a time, so we never have a problem with having enough charged batteries. Of course, there are times that a battery must be used more than once per day, and as long as it has had plenty of time to sit, it should be okay.
