How many batteries do you take to competitions?

[Foster]

How many batteries do you take to competitions? I was just at the Philadephia regional and made an effort to go an look at pits to see what they have. On average teams have 5 batteries and 2-3 chargers to keep them going. We were on the high end with 10 and three chargers.

[Rick TYler]

All of them!

(Our FTC program has three teams. We have eight chargers and about 20 batteries, including the 9.6v transmitter batteries.)

[Sean Schuff]

We have a custom designed/built battery station that manages the charges on 15 batteries. We have been known to loan out our batteries to teams in need and have gone so far as to provide space in our station to teams who can't bring more than a couple batteries to the event.

We had 4 main batteries this year, last year only 2. We have two chargers and always had two batteries on the chargers at all times. This is what is nice about being a Second year team. We also have 3 backup batteries(since I kindof lost this years but found it after we ordered a new one that was with me at all the robot meetings) and two chargers, so two were being charged while one was one the robot.

We bring 5 white (legal) batterys and 3 gray (old) batteries. The old ones are for in pit tests, and precharge of pneumatics. I marked 5-7

Do you have any pictures of this station?

[Josh Murphy]

We take 15 competition legal batteries and 2 non compettition legal batteries. We have six chargers on a cart and we charge them all on practice day, then cycle them on and off throughout the day on friday and saturday. That way come Elimination time we have a full compliment of batteries.

[DGrohnke1023]

1023 took 5 legal batteries and 3 old batteries to GLR. We use 4 of the old-style chargers for our new batteries and use this years charger for our cart and crossbucks batteries.

Warning to ALL Teams:
We had a batteries from 2007 go bad on us and refuse to hold a charge. The charger light was green but when we started the match the bot wouldn't move. A voltage check showed 10 volts. The battery was recharged and still only held 10 volts. We now check battery voltage before we leave the pit and after we turn the bot on down on the field. Batteries can go bad!

Team 93's setup was enough to turn even Green Machine Green with envy.

Thanks for letting us use a couple of your batteries, especially during the end there.

See you in Atlanta!

Someone ask 381 how many batteries they use. I don't want to steal their thunder, but you won't believe the answer.


And another vote for the amazing-ness of 93s system. There's no way we would have been able to get through all the elimination rounds on Galileo last year without it. It's a sight to behold, and works like a charm.

I bet they don't even need to use the batteries - they run off of magic!

[mmstucky]

I think we have like 7-8 batteries... We have a crate that has speed chargers fixed to the inner sides and it has fans to keep it nice and cool. It wored wonders at both of the regionals this year.

What does "speed chargers" mean? Remember that six amps is the maximum legal charge rate.

Hey 381, how many batteries? lol

We brought 12 to colorado

[Alan Anderson]

Our battery cart has slots for ten batteries and four chargers, and a fifth charger sits on top of it. I think we presently have it filled with batteries from this year and last. Our official qualification match battery rotation probably uses eight of them.

We also bring a couple of non-competition-legal batteries for pit use only.
