I use the ISOpwr+ to power any of my rigs from a battery and charge from a power supply or from my car. Has a serial interface for configuration for which I lowered the charging voltage to 13.9 to match my power supplies. Normally the application would be to use in vehicles with a secondary battery for isolation with the appropriate unit for my setup being the Super PWRgate PG40S or Epic PWRgate… or even an Astron BB-30M.
