It's not about the gear ratio, it is about the power. Any motor can be geared down so that you have enough torque, however speed will obviously suffer. Therefor you need a motor with adequate power so that you have enough torque AND speed.

What do you think about BAG motors? They have a nice torque and their RPM is high! Gearing it down shall allow it to do weight lifting, shoudn't it?

I dont think we are

That may be a great idea, because that will make sure that you pinch the power of those batteries completely.
Hey, I wonder if that would even be allowed. In a way, that is tampering with the battery and I think there are some safety problems with that!

For safety's sake, I work at a battery store and, from experience, I can say it would not be wise to tamper with or open up in any way, the competition batteries or any battery like them. The lead acid inside won't burn you, but it can eat away at clothes and it can be lethal if you touched some and it somehow made its way into anyone's body.

If you meant the marine battery, I wouldn't mess with that either. Although it has liquid acid in it, the same sort of thing goes like with the Sealed Lead Acid batteries; the acid won't burn but is toxic and will destroy clothes. The only way to actually stop the acid is with neutralizer.

bad advice.

I'm talking about desulfation using Ann ac current. Though that isn't physically taking apart the battery, it is still meeting with it in a way that could cause it to express.

By the way, I wish I was this guy:

I work at the store, we literally split these same batteries open and take out the lead for recycling. It WILL burn if you don't take safety precautions, but its common sense to take them anyways.

Though there is sulfuric acid in the electrolyte, the water dilutes it significatly. Also, the sealed batteries (like the one in the picture) aren't filled with liquid like auto batteries. It comes out as a sort of blackish-grey powder, very much like alkaline batteries when they corrode.

Opening a lead acid battery requires training and specific safety equipment, as I'm sure you are already aware.

35% sulfuric acid will burn exposed skin if not immediately washed off and can cause permanent eye damage if it gets in the eyes.

My concern is that your statement could be taken out of context and lead to harm.

For safety's sake I suggest you edit your posts to emphasize this.

As I said in my first post in this thread, it is NOT a good idea to open or tamper with ANY battery. Let not my intentions be misconstrued, I was only trying to provide relevant information.

So Valcore,
Are you wishing to allowing the cart to charge up the batteries on the go? Or do you want it to be just plugged in to initiate charging, or a hybrid of both?

Another suggestion might be to include chargers for rechargable drill batteries if your team uses cordless drills--we would never go to competition without our DeWalts!
