Go to an automotive store and ask where the mini blade fuses are. you need a 20 amp one.

Those types of fuses can generally be found in any auto parts store - try your local one!

We did the same thing, luckily I had a box of assorted fuses in my car.

Once we blew 3 (one of the students wired the motor positive to positive) we picked up an assorted box of 60.
And on a random side note TBA IS BACK UP!!!!!!

Update #5 allows (mercifully) the use of lower amperage fuses. So that assortment box may help you choose a lower amperage value. They are color coded. BTW the supplied 20a fuse is in place because for FTC robot use, the majority of robot power comes through that fuse, viz. two or more motors, several servos, controller boxes and sensors. So 20a makes more sense in that situation.

We did some quick measurements of our minibot.
It draws about 3.6A climbing up the pole. A single stalled motor draws about 6A.
We're planning on using 5A fuses to prevent burning them out. (Unfortunately, ATM breakers aren't offered in values less than 10A)
