I'm no longer including batteries in the case - you need to supply your own LiFePO4 batteries (BYOB) - hence the price drop 


The battery specification is a Lithium Ferrous Phosphate (LiFePO4) 3.2V nominal voltage, battery size 26650 - these are available in lots of countries.  


Single voltage case dimensions 4.72 x 1.69 x 3.07"


The ISO-PS is a battery power supply using user-replaceable LiFePO4 batteries delivering one or two isolated voltage outputs with continuous current output ratings of 2 Amps or more (but huge instantaneous current delivery headroom >120 Amps) - hence the stability of the power supply. under dynamic load.


Any single voltage from 5V to 7V voltage output comes directly from the battery supply. Other voltages are derived through high quality votage regulators. Optionally a TPS4700 ultra low noise voltage regulators can be used for 1 Amp outputs - just ask for this option in the notes on the checkout page.
