Here's a video of the mod tutorial itself if you prefer.
So first open up your Nomad Battery Pack and remove all the battery springs EXCEPT the ones circled in green. Those 2 are the ones that connect to the back of your Battery Pack.
Next, you're going to grab your dremel and remove all the plastic sticking out from the inside. It all has to go.
As for the Back side of the Battery Pack, you want to remove only the plastic tips sticking out from the middle that hold the batteries. You also want to remove the little circle sticking out located in the middle of the 2 rows of plastic tips you've removed.
Now with your Li-Po battery, your are going to cut of the Deans connector from the 2 thick, long red & black cables.
WARNING: As soon as you cut one of the 2 thick cables, a spark WILL pop out for a split second. While nothing serious, BE PREPARE AND CAREFUL FOR IT.
Once you cut off the Deans connector, go and cut off 1/3 of the red cable from the end. This will allow for easier adjustment when placing the red cable inside the Battery Pack. Next strip both ends of the thick, Red & Black cables and add some solder to the end of both cables. DON'T TOUCH THEIR ENDS TOGETHER.
Next. to make the soldering go smoother, strip the ends of the red and black cables, dab some soldering flux to them and add solder to the tips. Doing this will make things easier on you.
After that you're going to solder the RED(+) cable to the positive(+) lead of the battery spring and then solder the BLACK(-) cable to the negative(-) lead of the battery spring.

Once you finished this up, your work you should like the following picture. Notice that your other connector to recharge the battery has a nice little closing area below the red cable.
Now we finish it up by adding small dips of hot glue to the side of the battery or use some electric tape assure steady placement of the Li-Po battery.
Congrats! Now you have rechargeable Power Pack battery that WILL last for double the hours on a standard Sega Nomad. A Sega Nomad with an LCD screen mod will last you for even longer.
Later when your ready to recharge, hook it to your charger and wait till all 3 lights turn green for full recharge.
