Lithion-Ion Batteries

[akoscielski3]

I've had this question in my head for the past couple of yearss, but still dont have a real answer. Why don't we use Lithion-Ion batteries for our FRC bots?

My team has used a Drill since 2006 that uses a Lthion-Ion battery, we love it because it doesn't stop working until the battery has appsolutely no more power in its battery.

I know that they're illegal, but why are they illegal? And won't it be better to run at 100% power all the time? You would always have the motors spinning at the same speed, there would be no more variables.

Thanks
