Where to connect the Voltage Dispaly in my DIY Powerbank?
« on: October 31, 2014, 07:45:32 AM »
I am updating my samll Li-Ion Radio powerbank and i have found some space in the case for a Volt meter display

Sort of, cos it is not easy to connect it across on the main switch + pole.
I am thinking that wiring across the - of battery and on the + wire after the fuse (before the output connector) will also
- indicate a blown fuse when the switch is on
- show any drop of voltage from parasitic resistance inside the powerbox.
