Hi Rob, and John,
I followed your exact instructions and the lights behave properly and I am now into my 6th consecutive album. When I now power off the Mojo completely, the battery white light, which was white throughout the listening session, now goes off, so it was definitely in trickle charge mode. I guess my Mojo wasn't fully charged when I had that problem earlier, or maybe it was a yellow light and these old eyes of mine cannot be trusted. I apologize for any confusion caused.
I now have 3 questions, if I may:
1. If I leave the Mojo plugged in to the wall wart all the time, that should be fine, correct?
2. I presume that any time I want to resume listening in its present setup (meaning listening via the computer and with the charging cable still connected to the wall wart), the Mojo should be "ready to go" and that there is no need for me to ascertain the battery level?
3. If I then use the Mojo as a portable, and later on connect it back to the computer for listening (with the charging cable then connected to the wall wart again), what would be the minimum color of the battery light? Green?
Thanks once again.
George
John answered 1 and 2 fine, but I thought I would clarify exactly what happens when you charge and listen at the same time.
I use a dedicated charging chip for the Li battery, and this has a number of safety features, and works with a number of settings to ensure safety.
Now one of the safety circuits is a safety timer, and this is when the charger is in full charge mode. This timer is set to about 8 hours, and normally full charge mode takes 4 hours, when the unit is off. But when the unit is on and playing, there is a risk that the safety timer will be set, as it can take 12 hours to fully charge (from flashing red) and when playing music (for those 12 hours) at the same time. If the safety timer is set, then the battery LED will slowly flash white, and no further charging will take place. To reset the timer, just disconnect the charge USB, wait 10 seconds, and reconnect, and it will recommence charging. So if you are charging and playing, then when you have finished listening, turn Mojo off, and it will be OK. When Mojo is blue, and you connect the charger, then it is trickle charge mode, and the safety charger is not operating. So if Mojo is green, the safety timer won't trip out, as it will play and leave full charge mode within 8 hours, so you will be OK. It should be OK at yellow too. I guess the easiest way of dealing with it is to turn Mojo off after listening, then you will be fine, unless you listen for longer than 8 hours starting from fully flat.
Note that you can get the flashing battery LED if the USB charger voltage is low, from a charger that can't supply the current, or a USB cable that has high resistance. But you will see this pretty early on.
I hope this clarifies.
