Just to point out that batteries will only deliver a certain amount power. Depends on the rating of the battery so it may well be that your battery has just topped out in terms of current it can deliver.

Cheers guys.

featherweight typhoon was a drill motor, gearbox and all. It wasn't actually that impressive a machine.

[Chris230291]

Ow right. Maybe it was the middle weight? I remember you entered into a few catargories in robot wars.

So how would I work out the max current any battery can deliver? In my test I used two 14.2v lead acid batteries in series. (28.4v) there's no ah rating and there not the batteries I intend to use as there really heavy. If it helps ther by apc and out of one of there power backup units designed for computers when theres a power cut. I was thinking of going with lead acid. but I'll wait for you to tell me there pants haha. If you could answer either questions that would-be awesome.

You should be able to take the details of the battery and google a data sheet. This should give you battery capacity and maximum discharge capacity.

PS: BTW if it moves around for three minutes then the batteries are good enough

Cheers mate that's cool I'll have a look. As for the time I have the equation for that somewhere at home. Cant use the batteries I have, there way too heavy. I'm gonna look into some other lead acid batteries but go for ones with as low amp hourage as I can afford to go as to save weight. My plans are far too complicated I think already for the weight limit. My dad is gonna show me how to cad It. He says we can find a weight and even stress test it (get me) and see where to go from there. Now I think I have all the info I need. (cheers guys!) hope to be fighting as soon as and hopefully with a good reliable machine! I'll try and make some sort of a build diaray along the way too.

Cheers guys
