Yes soldering a wire from + to + and - to - is the only thing that's needed, then of course connecting it to the circuit (plastic top/connector).

The wires going to my cover is my way of charging my N900, i can charge it via USB like normal, but i use the cheap charger from DX that i link to somewhere, i can of course use any charger just as long as i limit input power to 2500-3000mA, this means i can charge it up VERY fast if needed (normal charging is 500-1200mA)

Also i can use that charge port to power external components, like my DIY mini addon AMP (link in signature), or power a HIGH power LED for VIDEO rec with proper light, or IR LED for HIGH power night vision Video recording.
The charge port (2mm DC Nokia Plug, like all other nokia phones use) is connected DIRECTLY to the battery's before the circuit, this is why i can Charge/Drain high currents
