This would be golden, otherwise!

Just an update, in 2.24, the backlight can be turned off while external power is in.

I'm now at about 9.5 hours of 44.1k WAV recording (internal mic, 20db gain, no backlight, no headphones plugged in)and my battery indicator is still reading 382! I wanted to test the limit, but I'm going to have to try it when I have more time!
Final cost for all the parts, with charger, was about $45 dollars.
Thanks Schwilly!

I just got a good deal on some batteries from batterySpace.com:
Three 1800Mah Nimh 9.6V RC batteries for $21.99
This compares to one 1600Mah Radio Shack Nimh battery for $19.99.
They also sell a cumbersome-looking pair of 3300Mah packs made of 8 Sc cells each for $49.99.
Also bought a $6 charger and shipping was 6.36. Products shipped next day. Very pleased. This should be enough power now....thanks Schwilly!

Hey guys, I think I've found a battery replacement for the HD Backpacks, although it might not give you much more record time or running time, it has a higher mAh rating (in fact there is two other ones) and they are the same physical size as the stock 2,000mAh one that's in there..
It's a Samsung 3.7v 2,000mAh battery, and I found a 2200 and a 2400 batteries...
Here is the link.. :P Enjoy boys!.. As I am still searching to see if there are same size batteries that hold a higher mAh rating.. :P ANY HELP WOULD BE GREATLY APPRECIATED!!
Here is your link Ladies And Gentlemen!
http://www.samsungsdi.co.kr/contents/en/product/battery/type01_ICR18650_20.html
And if that doesn't work, then pop in a search for exactly this into google and it would be your first item on the page.. :
samsung sdi 3.7v 2,000mah
Thanks guys! Got me on a kick.. Says it's supposed to last up to Ten hours, but I average about 4 - 5 hours on a full charge.. I havn't taken it to it's limit except when using the onboard FM Transmitter, MAN that munches up the power.. I think I got an hour of battery life while using that!.. HAHAhahaha

Does it matter what mA rating the extra battery has as long as its at least 1600mA? Or can you supply too much power?....it would be a 9.6v battery for sure anyway right? I have not had a chance to check what it says on the neuros charger so im not sure exactly what it would take to charge it. I know some things about elect, but not much.
also, when you build schwilly's version of the battery do you attach the adaptaplug socket to only the positive red wire on the rc repair kit or both the wires...pretty sure just pos...but not sure |

It doesn't matter what the mAh rating is- more mAh just equates to longer run time.
I would also STRONGLY suggest that anyone building something like this stick in some kind of current limiter- a regular fuse will work just fine. The difference between a wall wart and a bank of batteries is that a wall wart has some inherent current limiting, while a bank of batteries will happily supply a REALLY large current, right up until the load (YOUR Neuros) or the batteries fry/catch fire/melt/explode. There are resettable "fuses" out there, basically just thermistors that rapidly increase in resistance above a certain current, causing them to heat up and increase resistance, etc., thereby limiting the current.

Well, I'd have to say (about my previous post) that all of us should do some battery research, much like I did, to find a bettery that can fit inside the neuros, without having to have an external battery hookup, or (since there are firmware releases in the open source community that will allow the light to br turned off while on external power) maybe a sleeve type device that can hold like a long flat Lithium Ion (LiOn) battery pack that can put out say, 6,000mAh, or even 9,000mAh...But, keep the voltage at a steady 4 volts (assuming you can jump it into the circuit board in the HD pack directly) or redesign the backpack totally to fit a longer, larger battery.. IMHO long battery life as well as great features is just as important to me..
Just my input once again. Feel free to contact me..

The batteries in the head unit (the 256MB version) are two AA's and they are 1,300mAh... (there are two, but they are in sequence or whatever it's called so amperage stays the same, just voltage increases) so.. 1,300 x 3v = 3.9.. you should be getting close to 4 hours of playback at least.. or so.. maybe my mathis off, but the HD backback will give you more runtime as it has a 4v (technically 3.7v) 2,000mAh You're supposed to get roughly 10 hours of playback, but that is under ideal conditions, but for best results and to maintain playback quality, keep your MP3's to 128K or less encodings..
That will give you max bettery life.. the higher the bitrate the more processing power it takes to play the sounds, and thus shorter battery life.. :P

yeah,I have the 128MB version,let me pop my backpack on and give it a full charge.. remember the batteries in the regular backpack are just NiMh.. they suck, so they will develop a memory if you keep charging them when they don't need it.

Also, on another note, you should download and install a copy of GarBage branch firmware, infactI am gonna check for an update.. It will give you a numerical readout of the voltage from the battery.. so you know when you have a full charge..

Mike,
Would you be so kind as to post a link to a specific product that is an example of the current limiter that you speak of? I am interested in implementing this into my setup, but I have never been good at jury-rigging things on my own- I need a "how to for dummies" type thing. I am currently using Schwilly's Radio Shack setup with the RC pack, etc.
Thanks,
Nate |

Let me say somthing to this effect as far as batteries go..
Use whatever batteries you like, heck you can use a car battery if you feel like luggin that heavy bastard around..
As long as you don't exceed the VOLTAGE input of the device, you'll be fine. As an example, a car puts out a few hundred amps while running (a luxury car does anyways) and the car power adaptor does not have a regulator in it. that is built-in to the battery pack and the hard drive pack.
As long as you keep it between what 9v and 14v you should be fine, and you WANT more amp hours, that equals longer run times, so if you get batteries like RC car packs, that are at 9.6v and 12v, etc. and you want LONG runtime, you need to do it like this.
Say you have TWO battery packs (I am not gonna use the technical tersm for I have forgotten which goes to which series/paralell)
However, for the longer runtime, take two (2) 9.6v battery packs say that are 1,300mAh.. Put them together so the positive ( + ) wires are touching eachother, and the negative ( - ) wires are touching together, and you get the same 9.6v but with 2,600mAh instead of 1,300..
Did you catch that?
If you want to increase voltage but keep the same mAh rating of 1,300, you put the positive from battery 1, to the negative on battery two, then you use the left over positive and negative and connect those to your device..
If you are going to be hooking the power source to the inside of the unit (for instande the HD backpack) make sure the voltage to that doesn't exceed 4 or 5 volts.. as the battery is rated at 3.7, it puts out a tad more power than that, so I Would think it would be safe to assume hooking the power source internally would be save at anything between 2.0 and 5 volts..
Remember, so this doesn't get confusing;
Positive to positive then hooking it up to the device gives you longer runtime..
Positive to negative and the remaining leads to the device will increase voltage, but keep same amperage rating, best to keep the same voltage and amperage batteries together.. I don't know how to calculate the difference or hazards of using two differenyt battery powers together..
If I had the time, money and patience I'd post a link toa pic that would illustrate this.

Techie, the current is what kills you (not the voltage). Of course voltage is important, since the device has regulators spec'ed for certain input ranges. Current, however, is more dangerous.
But if you put in current safegaurds (like Mad Dog's suggestion), then that will protect you against damage to your Neuros. From Schwilly's original post, the current draw is 0.8A.

| Mad Dog, I believe thermistors decrease R with increased heat (inversely proportional based on 1/e). If this is true, and increased current leads to increased heat, then wouldn't that lower R? |
