Hi , I want to build a 48v battery for my motorised cooler. I apolgise if this has been asked a thousand times already. I did some searching on the forum. I know a lot about internal combustion engines but when it comes to batteries and circuits I know very little. A friend of mine gave me a large lithium battery. I have pulled it apart. I have pulled the individual cells out of it. There are 122 individual cells. They measure 65mm long x 26mm across. And they are holding approx 3.2v My questions are, how do I arrange them to get 48v please? Where do I buy the plastic holders please or do I hot glue them together? And what about using nickel strips spot welded on please? And if the motor I am using is 2000 watts - 48v, will these cells give me enough juice or amps for my requirements please? TIA.
