battery pack for Coolpix
I am trying to build one external batterypack starting with a 12V accu.
I now have 8.4 Volts. The fnial question is: 'how to connect the + and - to the plug that goes into the Coolpix?'
I also looked at creating a pack from 7 C-cells. Since a single C-cell (3000mAh) is in the range of 8 euro the total thing would cost too much, given that a DPS-9000 can be bought for $40.=
