Thanks to all who posted here to guide me through building the battery pack.
I ordered the $5.99 connector/thermistor and a 2300 mAh pack from all-battery.com ($15.99), as suggested, and wired it up. I soldered rather than crimped, since I have better luck with that, and I think it was no more difficult, maybe easier. I decided not to include the intermediate taps into the battery. I slit the plastic wrap around the battery pack and slid the thermistor down inside so it sits sandwiched in the middle, but probably doesn't have tight thermal contact with any of the cells. I packed some foam around the battery pack so it wouldn't rattle around in the hard plastic compartment when plugged in. I worried at first that this might not allow it to stay cool, but then again, maybe this is fine - the thermistor should stop the charge sooner, if anything. I have lots of experience doing this kind of thing, but it shouldn't be that hard for a determined builder. The hardest thing is working with the small parts and wires. I have now used it for about 3 weeks and have discharged the pack a couple times. I measured 9 to 10 hours of radio operation at mid volume the first time, and it seemed about the same for subsequent uses. So far so good. I really like being able to move it around, bring it with me to the backyard campfire and take music requests from friends for Pandora, etc. -- edllew ------------------------------------------------------------------------ edllew's Profile: http://forums.slimdevices.com/member.php?userid=35403 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
