Can we use other brand batteries if they are the same specs as the ones provided? If not, where can I get some? We are having trouble locating any.:confused:

For practice you can use whatever you dare to.
For competition you have to use the “EX18-12 *corrected]” batteries provided by first.
I think the closest you can buy to those are Exide ES18-12.

I heard from somewhere that exide made our batteries special for FIRST so they are deep cycle.
