Step 5ADDING LI-ION POWER!!!
This step should be helpful to alot of people trying to add li-ion or li-polymer power to their design. It is of EXTREME importance that a rechargeable lithium battery have protection circuitry. Your cell comes with this built into the package of the battery by the manufacturer. We purchase bare cells from www.batteryspace.com and highly recommend their Protection Circuit Modules (PCM). They basically work to isolate the dround of the battery from the rest of the circuit when a fault condition is encountered. This is especially handy in case you short something on your board. The power in the battery will quickly "vaporize" your copper power traces!
