I powered my Hapi with one AKD8DP converter board with a 12v 8 ah LiFePO4 battery, no AC connection. I recorded 8 channels w/ phantom power for four hours before I shut it down. I'm not sure how much longer I could have recorded before battery depletion, perhaps I will test this some day.
I have some questions about battery power in general.
1) With AC and battery for backup, will any current ever flow to the battery?
2) Is there a battery low-voltage shutoff point for Hapi and if so, is it adjustable for different battery technologies?
3) Is anyone else battery powering a Hapi? Have you run into any issues?
Thanks!

Re: Hapi battery questions
I received a reply from Guillaume in Merging tech support. He states:
There is no current flowing back to the battery if powered by both battery and AC supply, power lines are protected with diodes.
There is no shutoff point in Hapi, regulators on our power board can work with a voltage as low as 10V, but there is no mechanism that would shut down the Hapi if the voltage would drop below this stage.
We have never been faced to such a request before, if there would be more requests for it we may think of a solution to achieve this. A kind of workaround would be to regularly monitor the Hapi > Setup > Info page on the display or via the WebApp to see the level of the +12V power supply, you should see it dropping as the battery loses its charge.
