Can a power supply of 48-volt battery pack a 12 volt fan
If you don't have a 12V output. It can be connected directly from the battery pack, and the six battery units in series (which are 2V per unit in general, be measured with multimeter in advance), the lead is 12V. But be careful not to short-circuit your safety. It is best to be the first method, and the second method will cause the cell to be unevenly distributed, which will damage the battery
Is it a dc fan? If that's the case, use a decompression module and estimate a few dollars to a dozen or so. If the 48V is composed of a 12-volt battery pack, then the two lines will be straight forward
48 v battery is, but on general battery forklift truck has a DC voltage converter (also called DC - DC), find the thing, from the output voltage, find the 12 v output, wiring can be installed.
