Re: [SlimDevices: Radio] Radio battery technical info
Eskil, is this information based on your direct examination and measurement of a stock battery pack sold by Logitech? I have found conflicting information on where the voltage sense wire should connect. Some schematics show the connection to the positive terminal of cell #7, some show to the positive terminal of cell #6.

Re: [SlimDevices: Radio] Radio battery technical info
People with the Logitech brand battery have reported vmon1=4V and vmon2=8V, so it does seem that the correct connection point for vmon2 is the wire between the positive terminal of cell #6 and the negative terminal of cell #7. http://comments.gmane.org/gmane.music.equipment.slimdevices.radio/5594 John Stimson's Profile: http://forums.slimdevices.com/member.php?userid=218 View this thread: http://forums.slimdevices.com/showthread.php?t=87318 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio

You can get there by navigating: Settings - Advanced - Diagnostics - Power. I'm curious how they map from the plug.

So here are my findings: 10PCS 2000mAh Ni-Mh AA-cell 1 temperature sensor 10-pin JST PHD-series connector Following the numbering convention from the JST datasheet: Pin 9: Black, 0V Pin 7: White, Temperature sensing resistor of some sort. 11K at 27C, other end at pin 9 Pin 5: Green, 3.9V, 3 cells up from pin 9 Pin 3: Brown, 7.9V, 3 cells up from pin 5 Pin 1: Red, 13V, 4 cells up from pin 3 It's nice to see that the cells are protected against over-temperature. It's also the reason not to try to copy it, as the temperature sensor signal is probably well integrated into the charger electronics. It's also rather nice to avoid fire from the batteries due to the over temperature shut down. I haven't temperature-swept the temperature sensor to get a curve from it. In other words, I don't recommend making a DIY battery. Dont forget the resistor 191 Ohm for pin9 and pin5. Also don´t forget, to buildin a temperature-fuse approx 75° Celsius. 10kOhm 25° Celsius is okay Seems for me that u haven´t spent a long time to collect all data for ur DIY.

Re: [SlimDevices: Radio] Radio battery technical info
I bought the original Logitech pack for a quite different reason: I simply found it very difficult (in Norway) to obtain high quality batteries at a low enough price to justify the extra work of soldering everything together myself. The original battery cost perhaps 10% or 20% more than the best pirate pack I could assemble myself, provided I could order all the pirate parts in one shipment to save on the shipping costs. Which it turned out, I couldn't. When I also considered the risk of blowing the warranty, and/or blowing the Radio itself, the choice was pretty clear. -- Soulkeeper -that is not dead which can eternal lie. and with strange aeons even death may die.- touch + duet + boom + radio / wrt160n/dd-wrt / sbs 7.5.1 or higher/win7(32b)/avira free Soulkeeper's Profile: http://forums.slimdevices.com/member.php?userid=35297 View this thread: http://forums.slimdevices.com/showthread.php?t=87318 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio
