Mini bot fuse question
 

What I need to know, is what size fuse, that the mini-bot battery pack uses, and where to purchase them.
Thanks in advance for answers!

Im pretty sure the fuse type is called mini blade fuse

The fuse in the stock battery uses a 20AMP fuse, Since the motors stall current is around 7 amps I would recommend putting a 5 amp fuse in there.

This way the fuse will blow before the motors blow, just be sure to have extra fuses in hand. :)

We got ours at the local RadioShack: http://www.radioshack.com/product/in...ductId=2102772

They're just called mini-blade fuses.

You can also get the fuses from any place like Autozone, Napa, Advanced Auto.

Thank you!!! I knew this was the right place to ask for a quick answer. You people are great!!

Re: Mini bot fuse question
 

these are also commonly refered to as an ATM sized fuse.

Got a nice assortment box at our local Walmart with sizes from 2 amp up to 25 amp. Heavy on 7.5, 10, 15 and 20 amp sizes. Under $20.

Unless you are using 2 motors, in which case you probably want to go with a 10 amp fuse since together they will draw 7 amps at full power (14 at stall)

With a direct-drive minibot, I was blowing 5-amp fuses. 10 Amp works but makes me nervous. Maybe there's a 7 Amp fuse.

How many climbs/matches did yours last with the 5amp?

Re: Mini bot fuse question
 

For OUR tests, we lasted about 6 inches of vertical travel before the 5 amps popped. When our minibot deploys and hits the bar, the spinning shaft gets slowed down considerably and theres a definite current spike that occurs to get the bot moving.

We switched to 10 amps, been using the same one all competition. Our turn off switch is EXTREMELY reliable so we are less concerned about smoking anything with our system, so 10 amps may be overkill for your needs.

We used 5 amps for a bit, went through a fuse a match pretty much.

A team in NJ was using the 7.5A fuse as a shut-off for when it hit the top, I didn't notice any damaged motors. They did blow a fuse every match though.

Re: Mini bot fuse question
 

We use a 7.5 A, and replace it after every match.

Re: Mini bot fuse question
 

It immediately blew. Would not even start moving.

Re: Mini bot fuse question
 

We did the same, with a 5A. It's our stopping mechanism.

Re: Mini bot fuse question
 

Fuses are not for protecting components they are for protecting wire. Someone posted a link to the littlefuse data sheet for ATM fuses. They can handle much more than what is stamped on them for short periods, so I wouldn't recommend more than a 7.5A fuse.
