Re: 8 Batteries -or- 10 Batteries at Competition
We made a different investment. One of the mentors on the team made a load tester. We check every battery before it goes on the robot to avoid battery problems on field. But we only have 4 batteries. By being able to see the power that is given when a higher current draw is being applied we know exactly what each battery is going to give us every match.

With the load tester we are able to identify the bad batteries before we go to competition. When we first got the load tester 3 years ago (we were a third year team) we realized 4 of our 7 batteries were under performing and we no longer use them. Over the past couple years we have managed perfectly fine with 4 or 5 batteries with 3 chargers.

The MOST important thing we learned is load testing the batteries, instead of just testing with a voltmeter is essential to telling the true strength of a battery
