Step 7You're done!
Well, that's it. Took about two hours from start to finish and it went back into the case quite nicely. The Novak battery bars came with stickers. I love that, so I put a Novak sticker on this one so I would know which pack was my uber pack. Charged it, put it into the drill and it runs like a champ.
You can hear the difference compared to the stock battery. This puppy is just begging for some heavy drilling. Time to pull some screws out of a big crate.

Hi, my cordless tool uses 1.2ah sub c cells would this matter if i replace them with 2.0ah sub c cells or would this damage the tool?
The biggest danger for the tool is to have too high a voltage, as in heavy use the motor may burn up.
The other problem is with the charger. Your charger is very specific to battery chemistry. Each chemistry has it's own needs. NiCd is the simplest to charge. Hydride batteries are more complicated to charge, and a Nicad charger will charge them but they will have a shorter than desired battery life.
Lithium cells are great, but they need a precision charger. The voltage per cell is much higher, so you could possibly put in fewer of them, with larger Ah to get better battery life per volume.
You could possibly replace the guts of an existing charger with an off the shelf charger from the R/C market to take advantage of these cells.
Oh. The simple answer is just to keep the voltage sane. > Ah won't harm the tool.
You also need to test the connections as you go so you don't end up with shorted cells or wrong connections. If you want to build a battery superior to the original battery that will run any tool at any voltage, check out the Rambo Battery. The Rambo Battery kit is simple to build and it allows you to run your tools at a few volts over the tool voltage - 14.4 volt tool running at 18 volts for example. You will really enjoy the extra power and speed you get. You can also configure a Rambo Battery using NiMH cells rather than NiCD cells for much more power.
This is absolutely false. If you "overheat" the cells you can damage them, but people have been building high-performance racing batteries for RC for decades by soldering on battery bars.
Second, this sounds like a product advertisement and I'm tempted to flag it as such.
