A 5AH Earthx "backup" battery was recently linked here on VAF. LiFe with a brain seems like overkill for a simple voltage supply.
Earthx has a relatively flat voltage decay while AGM has a more linear voltage drop during discharge. I only need 7V to keep the fan turning to a runway when needed. So educate me, why I would select an expensive, complicated battery for this task.
