Q:choose external battery pack?
Hi Hadad, I have a galaxy s3 and an iphone 4s. I actually got a 6000mAh battery charger first but I found out that it can only charge my phone about twice. So I get another one which is RavPower 10400mAh. Cannot tell how much I love it. It comes in portable and does look like a neat one. It has 2 outputs so I can charge 2 of my devices at the same time. I would strongly recommend this one to you. You can get it from amazon store.
Q:Xbox controller w/ chargable battery pack lasts 2min?
Make sure that when you plug it, the little light turns RED. If it turns green too fast, it means it is NOT charging!! Try plugging and unplugging it. I actually saw a video where a guy said that if this happens it might mean your controller is completely drained, even so much as to charge itself, so what you should do is plug it, wait for the light to turn red, then when it turns green unplug it and plug it again, and then continue this process for several instances until it is able to charge itself! Hope this helps!!
Q:What items are absolutely necessary to buy with an xbox 360?
I would suggest getting the rechargeable battery pack because it'll save you a lot of money in the long run. Don't bother getting the cooler because it's just a waste of money. In some cases, it does more harm than good. Pelican, Nyco, etc. are just playing to gamer's fear of the heat. Not one person has said that their PS3 or Wii have overheated, but those companies still sell coolers for them. So what does this tell you about those companies? I also suggest you get some games and maybe an extra controller.
Q:what should I use to make a battery pack to use inplace of wall wart 12vdc 1250ma?
My suggestion would be to buy a sealed lead-acid battery, say 5 AH, which is fairly small and light, and try it out to see how long it lasts, maybe good for 5 + hours but you just don't know till you try it. . If it doesn't last long enough then you can buy another and connect them in parallel ( +ve to +ve and -ve to -ve) which will give twice the running time. A word of warning: A lead-acid battery, even a small one, can deliver a huge current if it is shorted by accident, this is what causes a lot of car fires. It's very important to put a fuse in the circuit to avoid the risk of burns or fire. Place it right next to the +ve terminal. A 2amp fuse in an in-line fuse holder will do fine. You will also need a small battery charger, your wall wart will probably do that job ok for such small batteries, see if you can get a gender changer so your power connector from the battery can connect to the ultranova AND the wall wart.
Q:Using a charger for a home made battery pack?
Be careful, Andrew. Improperly charged batteries can catch on fire, and even explode. You need to do a LOT more homework before you try this. For example, from your post I can tell you are not clear on the difference between a serial and a parallel battery pack. That's pretty basic, so I don't think you know enough yet to be hooking things up to live current. PLEASE do more reading! I wouldn't want you to hurt yourself or someone else.
Q:How does UPS and battery pack fit?
C6KS you can access 40 12V65AH battery (20 series in parallel) the remaining 8 spare, full load 4800W about 6 hours.
Q:I accidently froze a pack of AA batteriesThey any good now?
No, batteries lose their power when they get cold. Think back to all the cars needing jumped in the winter time. That is not a good thing for batteries to get cold.
Q:Can I mix different milliamp hour batteries of the same size in a battery pack?
very confusing factor. search at yahoo or google. that will could actually help!
Q:Battery pack question??????
complex stuff. seek onto the search engines. it could actually help!
Q:How Do I Work the Switchless Nyko Intercooler and the Nyko Battery Pack?
No, that is a waste of funds. do no longer stack your 360 in a shelf with out air circulate. An intercooler won't shop you from the RROD, neither will acceptable storage and utilization. each so often, that is inevitable. Microsoft will restoration it, and shop you the cost of the fan.
