battery power in android

[MarkHaysHarris777]

Well, my generic 8000mah battery seems to be no-where near it's rated capacity - is lasting about half the time I would have liked (basically overnight). I had intended to make it so the pine64 was charged from solar when the sun was up, and run from the battery overnight, but the battery is only just making it overnight, so won't last long with that near total usage, and doesn't leave any room for the pine64 do actually do some work.... this was with the pine64 idling. 

hi pfeerick, I am working with SLA batts at the moment. I posted in the DC POWERIN subforum;  I'm using the CPT module I received from Pine. I built a low_pass filter ( PI ) and have been playing around with powering via 12v on via CPT via PI filter on the euler buss. 

My interest of course is robotics.  I need some beefy batts for the 12v motors I'm going to use, plus I need it to keep the electronics up (for several hours, while the robot patrols the house). 

But, I was thinking the 12v system is the answer to a solar system also. The lith-ion batts aren't going to cut it, but a bank of 12v SLA batts I think is just the ticket.   Let me know what you think.
