My interest in building my own battery pack has stemmed not from the elevated price of the Logitech one, nor the scarce availability of it over time. Rather it has stemmed from the desire to have a longer "unplugged" duration so that it could be treated more like a power hungry smartphone that gets unplugged in the morning and then goes back to being charged at night. Truthfully wireless gadgetry is attractive to me to keep less cables out of the reach of the baby. Hence a long unplugged duration whilst he is out of his crib is attractive.
Most users with home built 2100mah packs seem to claim 10h vs. the 6h of the factory pack. Using the same math as well as the math from the german website linked throughout this post, a 2700mah pack could possibly garner 13h which would be just about perfect for me. While waiting for the smallgreencomputer.com kit to return to stock, I have been looking for existing packs which would yield a more professional looking result. The previously linked Tenergy 12V pack seems to have been reduced to 2000mah as opposed to 2300mah which some were receiving: http://www.all-battery.com/12v2000mahnimhbatterypack11606.aspx This 12V 2600mah pack seems to be too large despite being composed of AA: http://www.all-battery.com/12v2600mahnimhbatterypack11620.aspx (I have contacted them to confirm their measurements) I found this with thermistor already included, but only 2200mah: http://www.batteryspace.com/customizenimhbattery12v2200mahwiththermistor10xaa.aspx And this one seems off by a few mm: http://www.batteryspace.com/browseproducts/Customized-LiFePO4-Li-Ion-Module--12V-2700-mAh-(32.4Wh--4S2P-Rectangle-Pack--7A-rate-)-with-PCB.HTML The best pre-made I have found so far is this one: http://www.onlybatterypacks.com/showitem.asp?ItemID=12122 Sanyo 2700mah cells, which is what I was contemplating using myself. Best price on those Sanyo cells I have found is here: http://www.batteryjunction.com/sanyo-aa-2700.html (Would be about $32.5 pre-shipping for the right quantity) So only really a $20 savings over buying the pre-made pack from onlybatterypacks.com Keeping in mind that the idea of solving this for $50-$75 is fine by me, what are the best options for having the longest lasting solution which would still fit within the battery cavity for a clean solution? I am attaching to this post what I have gathered as the battery cavity dimensions of the SB Radio that I have. Thanks everyone for all the information provided in this thread already, I know it will be invaluable when it comes time to actually assembling whatever I settle for. Cheers, chGSD Post Scriptum: I realize the Logitech kit comes with a remote, but from what I have read it is pretty useless compared to the android apps available, which are working quite well for me at the moment. +-------------------------------------------------------------------+ |Filename: squeezebox_battery_compartment_w_notes.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=10961| +-------------------------------------------------------------------+ -- chGSD ------------------------------------------------------------------------ chGSD's Profile: http://forums.slimdevices.com/member.php?userid=42013 View this thread: http://forums.slimdevices.com/showthread.php?t=75056 _______________________________________________ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio
