As part of our rookie lessons learned for next season, does anyone have thoughts about the pros and cons of using rechargeable vs. regular batteries? Early on, we found that our robot performance varied quite a bit based on how fresh the batteries were, and we seemed to be burning through lots of regular batteries. So we switched to rechargeable batteries soon before the competition, but then had to tweak our programming because the output of rechargeable batteries is different from regular batteries! If we stick with rechargeable batteries for our next robot design, are there any potential problems or downside that others have experienced?
