as for over volting drill motors ive had my 12 volters running at 24v for over half a year. it uses 95mm wheels with hard plastic tread.
the only time ive blown up the motors is when i put tread on the wheels.... go figure.
it must be said though that the acceleration, power and speed is more than impressive at 24v :D
Weve been running two 14.4v drill motors in our 4 wheel drive for almost a year now - same motors!
Started off at 14.4v battery, but that wasnt fast enough with our 120mm Monster truck tyres, so now running at 18v Technobots Bot-Pack. Had to change the speed controllers to handle the rather large current (skid steer, 4 wheel drive, big fat grippy tyres) to a pair of George Francis H6s. Now get superb speed and control, and the battery lasts more than one fight. Only problem now is getting rid of the heat build-up inside the bot. Should be fitting some fans this weekend. :)
Woody, your right about the fact that the motors use the same amps but the valve and the 24V compressor wont. They will use less. Becaus Im not overvolting them.
And Ewan, do you have al link or somthing like that for the so called booster?
Thanks again

Here is an example of a low voltage booster.
Woody, youre correct about that. If you overvolt your motors. The current will increase by the same factor as the voltage, meaning that the total power will be square of the voltage increase.
However, I think he means that everything will use a fixed amount of power. So that when lowering the voltage, you need to use more current to substain the same amount of power.
But why is 24V the goal? If you have 1Ah on 24V or 2Ah on 12V doesnt matter, its all the same amount of energy! But more importantly, the same amount of weight.
For example, imagine that your robot needs a fixed amount of energy to funtion properly during a 5 minute fight. Then it doesnt matter wether thats 24V and 2Ah (which equals 576Wh), or 12V and 4Ah (which also equals 576Wh).
So while a 12V system will use twice the amount of current, itll use half the amount of volts compared to a 24V system (which equals the same energy). So youll carry the same amount of battery anyway.
But if Ive understood correctly, youre also going to power a 24V compressor? Then youre only option will be to go for a 24V battery and lower the voltage for the drive motors. As a voltage booster cant handle the current of a compressor.
What compressor??? (I think you must have been talking elsewhere :))
Nope, he said so above:
Woody, youre right about the fact that the motors use the same amps but the valve and the 24V compressor wont. They will use less. Because Im not overvolting them.
ah, I missed that... (slaps head...) but yeah, if your using a 24v compressor then no average booster will handle the current. Would it be possible for you to get some 18v or 24v drills, that would be a simple resolution to the problem, (running on 24v).
I run 14.4v drills on 25.2v in pimp 2 with no problems, the wheels are 90mm diameter and 50mm wide and it goes like stink (unless the disc is turned on)
So you can overvolt the 14.4V drills to 24V?
