Hi
I have a pair of (fairly) low-amperage devices I´d like to power with SLA-batteries;
- a 12V/7,2 Ah powering an Alix 3d2 motherboard (not sure of amperage but it consumes 3-5Watts with a 12V powerbrick (unknown effiency))
- and a 6V/12Ah battery for a QNKTC Usb-Dac (thus currently running on 5V ( 4.75-5.25V ok, 6V maximum according to manufacturer) amperage 24.4mA measured by user
1. challenge: How/best way to lower the voltage from the 6V battery?
(I measure 7.9V across the terminals fully charged..)
I know this can be done with on or more resistors or diodes in series with the battery - or with a regulator.
Any recommendations/other solutions?
