@JasonNYC, is this battery protection mode available for ca1000 OG, or are there any plans to add it with firmware updates?You didn't ask me, but I took this from Astell&Kern's website:
"The ACRO CA1000T has a battery protection mode feature that helps extend battery life. When battery protection mode is enabled, the battery is charged up to 85%, and then the charge stops. If the battery drops below 80%, the battery will start charging again and charge up to 85%. (Battery protection mode will be supported through a firmware update.)"
I received my CA1000T the other day and can confirm this firmware update is not out yet, but by the sound of it is in the works! When it is released, you should be able to leave it plugged in indefinitely if you'd like.
Thanks.
