Q:I have Rock Band drums that take 3 AA batteries and I don't want to waste batteries. Is there a way to make something that plugs into the wall and connects to the battery sockets (1.5 volt)?

I assume there's no external power connector on your drums (bad design in my opinion). There are some products in the market that do what you say, but they are specially made for specific devices such as professional flashes and cameras. The problem is that each battery compartment is different, and you also have a problem with the door. I think you're way better off by getting a good set of rechargeable batteries and a wall charger. Buy brand (Energizer, Sanyo, etc), you'll save money in the long run.

Q:I need to build a battery pack that will last a min 2hrs to power a motor through a speed controller. The motor will be run at the slowest speed possible.Motor Specifications:? Torque: 12.0kg/cm? Rated Voltage: 12.0V? Operating: 4.5 - 18V max? Current - No load: 70mA? Current - Full load: 1380mA? Gear Ratio:

Cannot answer, as you have not given the load on the motor (current varies from 70 to 1380). Speed makes little difference. And is there anything to show how much current the controller uses? They don't use nothing, you know. No free lunch. Read the amp-hours on the batteries to determine how long they would last under a given draw.

Q:i put in the pack it came with, it charges and turns red on the bulb.but i just put in newly bought rechargeable energizers but the bulb doesnt turn red. is it charging.

it only charges xbox rechargeable batteries. not real batteries

Q:i dont know whether they come with a rechargeable battery pack?? answers please im stuck?????

You can actually plug your controller into the cable without a battery pack and your controller will work. But it will only recharge plug-and-play batteries, not rechargeable batteries stuck into the battery pack.

Q:Hello Today I Got My Evader EXT RC Car In The Mail With A NiCd Onyx 1800 Battery By Duratrax Anyways On The Back Of The Battery Pack It Says Waring May Cause Cancer Birth Diffects Reading This Scared Me Are They Saying That By Holding Or Handling This Battery Will Cause Cancer I Really Hope Not If Someone Can Give Me Some Reassurance That It's Not Dangerous To Handle This Battery I Will Feel Alot Better If I Knew It Was Safe To Hold And Touch If Someone Can Please Give Me A Answer I Would Greatly Appreciate It

just dont saw it open and eat the insides :D if its covered in plastic the battery cant harm you. good luck!

Q:I want to find an external ipod battery pack that works with the ipod nano 3rd gen. and doesn't add on a lot of bulk. The best battery pack I've found so far is the Tekkeon mypower battery pack, but I'm not sure whether it works with ipod nanos. If you find out please tell me. If you find any other good battery packs that are nano compatible please tell me.thanks

try OKorder they have a lot of selection and good prices!!

Q:How do i make it so i can plug these into the wall, it takes 3 AA batteries, can i take an old plug from a small appliance and somehow just connect the wires? a really detailed explanation might be needed please and thank you

o.k. your best bet is to figure out the draw or power used by the LED's 3 AA's put out 4.5 volts and if its a good alkaline battery it will have about 1300-3000 milliampere hours. what i would do is find my self a 9VDC adaptor wire in series a quarter watt resistor that would bring it down to 4.5 volts to figure this out you need to know how many amps it draws please feel free to contact me i can answer any other questions you may have

Q:I know that NiMH batteries self-discharge over time, but mine are discharging in just a matter of hours. I am using them in a RC airplane. They are 9.6V 650mah AAA packs. I charge them up just as they should be and they put out full power when I test them in my plane. I go to the gym for a couple hours and stop by the flying field on the way home, but when I plug the battery in the motor on the airplane immediately goes to cut-off.An interesting note: If I hold the arming button down to keep the motor going, eventually it will work itself up to putting out enough power to do some low powered flight and will last the duration over normal flight time for the airplane

one or more of the cells has failed leading other cells to discharge into it , buy some tagged AAA cells and rebuild the packs

Q:What are the characteristics of the series and parallel battery packs?

Battery in parallel, the same voltage (the premise is the voltage of the battery can be connected in parallel, otherwise the voltage will be low on the low charge, if the difference may be too dangerous may be dangerous).

Q:I got a Nintendo Wii for Christmas last year. I am trying to charge my Wii remotes. I have two remotes. I am trying to find out how to use the battery pack. Can you use the battery pack? How do you use it? Also, is there another way to charge Wii remotes?

Do you have rechargeable batteries or a Wii charger kit? Because you can't charge your Wii remotes with the standard equipment included with the Wii. You have to either - #1 - Put fresh batteries in the Wii - either new batteries, or buy rechargeable AA batteries with a charger. #2 - Buy a Wii remote charging station. This is probably the battery pack you are referring to. The battery pack is inserted in place of the AA batteries, then the whole remote is inserted in a charging dock to charge.
