9v battery adapter for power funtions

this is a adapter that connects the Lego infrared receiver to a 9v battery. Its very handy because it replaces the $99 dollar rechargeable battery box from Lego, instead you can build this adapter and with 4 or so $12 dollar rechargeable 9 v battery and $25 BATTERY CHARGER you can keep on running you train only stopping to replace a battery when its gone flat the waiting for it to charge back up.
From what i can see a 250mAh Battery Lasted 1 Hr 20 Min at speed 2 or 30 Mins at full speed.

Good thinking 99; but how do I make one of those connectors?

My guess is find right wire for -/+ and wire it up as simple as that LEGO stuff is so simple not like my computer lol.

I think I mite look in to this as it would make it a lot easier to power stuff with out a big battery box.

I did a similar vid on MOC pages showing how to do this. People just laugh at me:(

There are flaws in the system, if you have this as an output via the IR receiver to a 9V motor (no electric track) you will burn out the receiver. (as i found out when doing mods to my emerald night)

I would recommend you don't use zcr2244's method. The reason he has burnt out his PF receiver is he joined the +/- power wires with the +/- control wires which causes a short with any of the smart PF devices. There are better methods of doing this. You want to find the ones that correctly identify all four wires.
