The Li-ion 4-cell power supply we will be describing is equal to $100 power supply (from a model railway supplier) and the $35 Power Supply (we will be describing) using 5 Li-ion cells can be used as a BENCH POWER SUPPLY for all your testing and is equal to a $100 product. And some of the other power supplies we will be describing will cost you either nothing or just a few dollars. constant current mode, the power supply will maintain the set current regardless of changes in the load's resistance. A typical example of this type of power supply is B&K 1621A shown: This power supply outputs one adjustable voltage, which is indicated by the one set of banana jack terminals. The above arrangement of output terminals with the
