12v

I would like to run this motor intermittently using a portable drill-type rechargeable battery pack, maybe lithium-ion. How long could I expect it to function with say a 30 percent on/70 percent off duty cycle before it drains the battery?

I have a 240V AC to 12V DC adapter that is putting out about 2 amperes. I need to take it down to about 2.2V DC to perform an electrolysis of water. I don't know how to do this. A way to take it from the adapter would be good but I can work from the 240V AC if need be.

I have an M-Audio interface but I lost the power source. Can I use a 12v wal-wart to power it? Or do I need to buy a new 9v source?

I want to power a 12V computer fan using only 2 rechargeable batteries (around 1.2 volts each). The question is: can you give either: 1. A simple circuit that I can build with basic components (transistors, resistors, capacitors, inductors, transformers, coils etc.). Preferably without ICs, but...

I am making an electronic gadget that is powered by one of those small MN21/23A type 12v batteries. Battery approx size is 1 1/8" (28.5mm) x 2/5" (10.3mm) Can anyone tell me where I can get a small battery holder for this exact size of battery? I have looked at Farnell, Maplin and one or two...

and if u can, could u tell me? because i took apart a electric scooter and the batteries are still good and i need step-by-step wiring instructions. they are rechargeable batteries and i hooked them up to the on and off switch and the recharge jack.

Symptoms: Runs ragged Very Low power, take close to a mile to hit 50mph Stutters, feels very jumpy when idling or accelerating Sounds odd, hard to explain but deeper. What I've done to remedy: Change out my injectors, the 330 injectors I originally had were trashed, I went back to stock...

it works but will it burn up the radio?

I'm going to charge parallel or lengthwise as opposed to series. I'm sorry 10 batteries not twelve.

Hi, Please can someone give instructions on converting a "NON" slim ps2 to 12v (car) power supply. Many thanks
