Is it possible to remove the internal Li-ion battery from my SkyFi 3 and power it exclusively through the micro USB port?
Here's why I wish to do this:
I'm using SkyFi 3 in a 16" Dob with ServoCAT. Everything resides in the bottom of the rocker box, and SkyFi is connected to the ServoCAT via a USB cable.
When observing I'm powering the SkyFi via a 12v to 5v regulated power supply/charger through the micro USB port on the SkyFi. When everything is turned on the power supply provides power to the SkyFi and I never have to worry about it losing power through a long observing session. So far so good, the system works great.
BUT... I observe in Michigan where it is not unheard of to observe in winter temperatures as low as zero degrees F, sometimes even below zero. I store my scope in an unheated space, so I don't want to worry about setting up the scope, turning everything on, and having the power supply/charger fry the SkyFi's Li-ion battery because it's below freezing. And I'd rather not have to remove the SkyFi unit at the end of every observing session and replace it at the start of the next, since it's tucked out of the way in the bottom of the rocker.
If it can be powered exclusively by the power supply/charger, with no battery inside to worry about, then it becomes simply a turnkey system.
Removing the battery also obviates the need to unplug the SkyFi from the ServoCAT at the end of each observing session, because leaving it plugged in drains the SkyFi's battery (see my other post on this subject).
Can this be done?
