[Eee Pad Transformer General] overkillthemighty:
So many people misunderstand this! The reason why RC LiPo batteries bloat/start on fire/explode is because they are

just a battery

. There is no protection, no regulation, nothing to prevent the battery from being mistreated. Those batteries are directly charged and depend on an external charger to balance and stop charging them externally. That way, they can be charged much faster, are cheaper to manufacture, and can push out more power than if the protection was built in (an external unit is usually larger than the battery. Usually when an RC battery goes belly-up, it is due to the user being an idiot or a malfunctioning/cheap charger. I am an RC enthusiast myself, I own 3 hellis and 2 air boats, so I am not just blowing smoke up your @$$.

Now that we know why RC batteries have a bad rap, we can learn why they are completely different from the batteries in consumer electronics like, say, the Transformer! For a nice picture of the difference for those who still don't understand, see the included drawing.

The transformer (as I mentioned before) Likely has a boost converter to jump up the voltage (though luna_c666 has a good point that it could just be using a balancing charger or it may be using a sort of combo to de-couple ground allowing it to charge both batteries simultaneously) The reason for the 15V also likely has something to do with pumping more power through smaller wires and connectors. The iPad can charge at up to 2.1A I believe, which is 10.5 W (2.1 x 5), while the TF is able to charge at 1.2A x 15V or 18W (Take that Apple!) with a thinner wire, as the diameter of the wire is directly related to the amperage, not the voltage. That was a bit of a tangent. Anywho, the transformer uses an IC that performs a similar job to THIS one. So basically, all that the official charger does is check the status of one of the USB 3.0 pins and either outputs 5v with a maximum of 2A or 15V with a maximum 1.2A. It doesn't balance the batteries, it doesn't regulate current (besides it's physical limitations), it doesn't sing the transformer a lullaby. So, the transformer doesn't care if you give it 12V with a maximum supply of 1,000A or 15V with a maximum supply of 1.2A, the charge controller will draw what it needs and be happy, and the transformer will charge. Batteries won't explode, baby seals won't get clubbed (by your TF/charger setup anyway), and you will have a happy full battery.

[Eee Pad Transformer General] xxgg:
Now that you have clearly explained it ! ;)

Another question now arise,

Transformer will than automatically prevent overcharging when batteries are fully charged ?

Than why do some car chargers say it has built in IC (or whatever it is called) inside them to prevent overcharging the battery?

Would appreciate your answer to make me feel more safer :)
[Eee Pad Transformer General] overkillthemighty:
I think XKCD explains this best...
[Eee Pad Transformer General] xxgg:
Heck, use my LiPo 3S as power source
[Eee Pad Transformer General] WhiteAsIce:
I followed all the steps, but I don't have a soldering kit, so I couldn't do that part. The charging light is lit on my tablet, so it would seem that I successfully built this charger. However, after leaving it plugged in for over an hour, the battery percent is still the same. Did I build it wrong? Do I have to solder the wires?
[Eee Pad Transformer General] Grey Yim:
good!

but i need pictures.

plz make a manual~
[Eee Pad Transformer General] micaman:
I've been wanting to try this for awhile now. I have a few of these lipos

http://www.hobbypartz.com/98p-40c-5000-3s1p-hardcase-direct.html

sitting around and thought they would make a great portable way to top up the tablet when needed.

I have a cell voltage monitor http://www.hobbyking.com/hobbyking/store/__10952__Cell_Log_8M_Cell_Voltage_Monitor_2_8S_Lipo.html

and a Watt meter

http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=10080

that I could use to monitor the charge process.

It would be interesting to see if the 5000mah in the Lipo is enough to charge a drained tablet without going below 3.5V per cell on the Lipo.
[Eee Pad Transformer General] micaman:
OK, so I was a little bored today and figured I would give this a shot. I really don't have a specific need for this but I already had this stuff laying around and i thought my findings would help those in need for a portable power solution for an extended time.

Required:

USB 2.0 extension cable

3 cell 5000mah Lipo battery & lipo charger

Connectors for termination

Instructions:

See attached photos

Things of note:

Auxiliary battery charges the tablet at 40% an hour

Tablet draws around 1 amp while charging then drops down to around half of that when it gets to 95%

To obtain a full charge, starting with the tablet battery at 10‰ and the auxiliary battery fully charged (4.19v per cell), it dropped the auxiliary down to 3.82v per cell and 2549mah (well within its safe limits)

Questions?:

Feel free to ask away
[Eee Pad Transformer General] flynike:
Worked great for me

Joined so I could tell my tale and say thanks for the info. Bought a used 201 on a popular site selling big box store trade ins. Knowing nothing then of the high voltage charging requirements, I also ordered a usb cord on eBay. Cord and tablet arrived. Tablet dead as a doornail. Plugged cord into my iPad charging block...nothing. Got nervous as from time to time there are DOA products from the source I bought from.

Got on the web, learned about the charging requirements, and found this post. Ordered a 10.99 wall charger from eBay, with an 8 day delivery wait.

All this time, tablet is plugged into 10W 5V charging block. Nothing. Had an old in-cord 12V 2A notebook power supply. Used it with these instructions to make the charger. Took an easy hour, after I collected materials, all on hand stuff. I enclose a photo; obviously no worries over a too-short cable.

Plugged it in. Finally, little light on start switch was lit, but still noting on screen. After a short time, was able to start up the tablet, and happily watched the battery move toward full over the next couple of hours.

With 5 days still to go before delivery of the dedicated non-OEM charger, I am happy and assured that I have a tablet that works. So, again, thanks to the original poster, and to the posters of the replies.

so i just noticed on my focus running mango that a update is available for my phone tells me to connect to pc to do it... anyone?

mypc die few days a go.. firkin motherboard..blame 4ghz

typo on title WP7
[Windows Phone 7 General] Peew971:
Samsung is pushing a pre-mango update for the Omnia 7. Maybe they also have one for the Focus.
[Windows Phone 7 General] adiliyo:
if the OP is on the mango beta, the only update i could imagine it asking for is if they aren't on 7712 yet. other official updates for anything pre mango shouldn't show up as being available since the system should be newer than the update....

personally, i haven't seen any update messages, i'm on 7712.
[Windows Phone 7 General] ajftl:
yea I'm on 7661...
[Windows Phone 7 General] adiliyo:
then the update it's talking about is 7712, if you are able to, i'd do it, it makes the OS run even smoother than before and ads a few more new things.
[T-Mobile LG G2x] slowpig38:
i just called in and spoke to a rep. After telling her how i have had 8 g2xs and i don't think the G2 is a comparable phone, she told me about other upgrade options. she offered me a sensation for 220. think this is a good offer? my current G2x is a pretty good one, it doesn't reboot often at all and if i run gps test before navigation it works fine. the only issue is it sometimes will turn off while charging overnight, but when i turn it back on it is still fully charged. I know the sensation also has some big issues, so i really don't know what to do.

also anyone want to buy a g2x for 220 lol? (not really serious, but i kinda am).
[T-Mobile LG G2x] supersilko:
im starting to think that most android phone have problem gotta be the OS
[T-Mobile LG G2x] :
Yeah man. Its not your phone its the software or your configuration, you should have figured that out after that many returns. what are you running?
[T-Mobile LG G2x] AdamHart612:
You went through 8 replacements? Ever heard the saying "insanity is repeating the same actions over and over and expecting different results?"
[T-Mobile LG G2x] BarryH_GEG:
If you're unhappy and think you'll be happier with a Sensation than it's probably worth the money. Others have posted they got a Sensation for free while some have said T-Mobile refused at any price. So you're somewhere in the middle.
[T-Mobile LG G2x] slowpig38:
please dont tell me it's what i am running. i have had this phone on stock gingerbread. and done a factory reset. but it still couldnt charge over night.

and my soccer coach has told me insanity is doing the same thing and expecting different results. when i hear that i look to tmobile, shipping out more g2xs that they know are defective and wondering why all these people keep coming back for exchanges time and time again. Every time i call in i ask for a refund or a sensation, i don't want to be caught in this exchange cycle, its all T-mobiles fault!
[T-Mobile LG G2x] eagle1967:
scam

NO do not give them 200 bucks to replace a phone they sold that was defective.

i have seen many say they had results through the BBB. so thats worth a try.

Keep fighting dont give in!
[T-Mobile LG G2x] supersilko:
if they think your mad enough they will give you a refund thats how I got mine.

I got G2x for about $550 through tmobile and started seeing problem on the first week so I keep bugging them after a month of disappointment when my return date is overdue and they still gave me my money back. What I do with the money 550 is to get a refurbish one from craiglist for 200 that doesnt have bleeding screen like my first one and I saved 330. so try to return that and buy a new one from people on craiglist that are moving to sensation not knowing that it sucks more.
[T-Mobile LG G2x] slowpig38:
I have tried everything. I even had my dad who is a very successful business man talk to a Rep about how I deserved a refund and he even got technical and started coting regulations. The dude proceeded to be an asshole and told my dad good luck in small claims court. And then hung up. It mmade me want to throw my g2x into a wall
[T-Mobile LG G2x] eagle1967:
this doesnt surprise me from what i have heard about tmobile lately. but if you havent done the BBB thing yet give it a shot.
[T-Mobile LG G2x] moeahmad1995:
What is BBB. Sorry for being a noob?
[T-Mobile LG G2x] tackleberry:
**** deal. Don't go for it. All they are doing is moving your upgrade up.

As for the people saying 8 is crazy I went thru 7 g2 phones. 5 in a row were defects out of the box. Its not likley to happen but it is possible.

G2x with CM7 and faux kernel. NONSENSE!!!!
[T-Mobile LG G2x] dilwaala:
BBB = Better Business Bureau.

You can call them up and complain about T-Mobile's response to your genuine issue. They will then communicate with T-Mobile on your behalf and try and get a resolution for you.
[T-Mobile LG G2x] web_ninja:
Ya don't pay the money for the Sensation... i really love my G2x sure there is a little screen bleed but it still is blazing fast,,, just my 2 cents....:D
[T-Mobile LG G2x] smashpunks:
No way.there gonna take your upgrade and your cash and you well hate it even more..

I called it the crapsation... Cause it was crap..

Good g2x > sensation
[T-Mobile LG G2x] slowpig38:
all I ever wanted was a good g2x. But I have yet to be issued one..... and I might wait for the Hercules now.
[T-Mobile LG G2x] slowpig38:
Also how long does the bbb take. I filed one like 5 days ago with no response
[T-Mobile LG G2x] tackleberry:
Yea, I did the same thing. I got no response as of yet, 4 months and counting.

G2x with CM7 and faux kernel. NONSENSE!!!!
[Optimus V Android Development] Hyeagley:
This is my first post on this forum so if I step on any ones I apologize greatly and I also apoogize if I use terms correctly feel free to correct me I am still learning a great deal.​

I recently bought the Optimus V from Virgin Mobile, I really liked the price and all its features, but I slowly began to grow tired of its simplicity and also of the general look of Froyo. I tried different Launcher replacement and themes but they seemed to after a day or so hinder the OV's performance.​

I started exploring rooting and downloaded Z4root. I tried repeated times and it just force closed. So I read on XDA of the differrent ways to root via USB connection though your CMD and Super One Click but I began to get confused and very frusterated. So I ended up trying Gingerbreak on a last minute attempt.It worked on the first try with in 5 minutes! Then I decided to flash a ROM on it. I tried ROM Manager for about 3 hours unsuccessfully tho only ROM I actually flashed was the Stock Optimized ROM. So If your thinking about flashing with ROM Manager dont!! Flash the Thunderc Recovery its quick and painless just make sure when you use the following code make sure the flash image and the recovery name in your code corresponds with the file you placed in your SD card root! Mine did not and it took me awhle to figure out why it kept failing.

In an ADB shell:

> mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system

> cat /sdcard/flash_image > /system/bin/flash_image

> chmod 755 /system/bin/flash_image

> mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak

> mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system

> flash_image recovery /sdcard/recovery.img

> reboot recovery
​

Place the rom you wish to flash in its zipped folder on your SD card. I placed alll my ROMs in one folder for orginization I called it AAROM so it is the first folder in the flash from zip menu. Before ou proceed be sure and backup your current System. Now you navigate to the flash from zip menu in your recovery and selet the ROM you want. It will begin to install when its done reboot and your new ROM will boot up. To access recovery again simply press power volume and home key simultaneously.​

I have been running Reborn ROM for 3 weeks and love it I have ajusted it to fit me andmy needs. My Optimus is overclocked to 825 MHz and runs everything I need it to. I am capable of playing games such as NOVA and NFS.​

Does anyone know how or if there is a ROM or someway to allow the Optimus V to use Flash? If its overclocked high enough it could techincally handle it right?​

**UPDATE**

I am now running CM7 with REMIX RED add-ons. Best Rom I have ever used CPU is overlocked to 825! EVERYTHING is perfect I love it!

[Motorola Triumph] ynk1121:
I know some of you aren't going to believe this but all I did was plug an HDMI cable in and now it won't turn on. Plugged it into the tv, then the phone. Phone completely locked up and turned black. Was totally unresponsive. Waited a few minutes and yanked the battery. Now it's stuck in a boot loop. I get the motorola logo, virgin mobile logo, and then it restarts endlessly. :mad: I rather not return it because of all my personal info on it. Any ideas how to either fix it or wipe all my stuff from it?
[Motorola Triumph] johnnycsx:
...yeah I don't believe you. But what matters lol, I don't think there's anyway to restore your data. You can fix it by installing Clockworkmod and flashing an uploaded backup. Just search a little bit for it.
[Motorola Triumph] ynk1121:
Yeah, I said that because I wouldn't have believed it either. I swear, I did nothing to it. Was working fine all day. Got an HDMI cable in the mail today. Plugged it in and infinite boot loop... :eek:
[Motorola Triumph] ynk1121:
vol +, vol -, & power is supposed to get you to recovery, no? I just get an android with a "!" in a triangle. Think it's toast?
[Motorola Triumph] ynk1121:
OMG! I'm back up and running. Here's what I did to fix it:

From start up hold Vol+, Vol-, Power. When you see the android let go of the buttons. Press home once (that's what confused me at first). This will bring up the menu. Vol+ moves up. Vol- moves down. Back arrow is to select. First I wiped cache partition with no luck. Next I chose "wipe data/factory reset". I have to reinstall everything but at least it works now. :p
[Motorola Triumph] maxpower17:
I'm too lazy to look for it, but I saw a thread somewhere about 3 weeks ago about cheap hdmi cables toasting people's phones.

I bought a 15 foot cable from monoprice and it works fine for both mine and my wife's Triumph.:o

I'm probably going to pick one up from there. :p

I'm hesitant. I think I'm going to double check it with a multimeter first and make sure there are no shorts.

That's scary. You think you're saving yourself a few dollars buying a cheap wire and it ends up taking out a few hundred dollar device. :eek:
[Motorola Triumph] JL13:
i definitely believe it. the hdmi mirroring works fine until i disconnect the cord from the phone. sometimes my phone's screen just remains black and won't respond to anything. only thing i can do is a battery pull. hopefully it isn't an issue with the hardware..

2. Put it in your Phone Memory

3. Go to Recovery

4. Flash the latest Cyanogen

5. Then go again to recovery > Mount and Storage and: Format your System / Cache / Data

6. Flash MIUI

Without giving the number I assume you don't need a response so most phone companies have a email to sms service. Good for sending a message without a response.

Or if you need two way conversation just use textplus from the market and create a free throwaway account.
