I am about to embark on building a 16.8Kwh battery pack out of the following:
960 3.2V 5.5Ah Tenergy round cells
An SuPower Battery 16S 150A BMS from batterysupports.com. *
10mm 0.15" Pure Nickel strip from batterysupports.com. *
(* Assuming the shipment from China ever actually gets here.)
Using a DIY MOT spot welder.Putting them in a 16S60P configuration. I am planning on 2 sets of 3 rows of 20 cells 8 cells deep and then putting them on top of each other in a reverse direction to get to the 16S and so both terminals exit on the same end of the battery pack. I will end up with a pack 24" long X 25" wide X 7.5" tall battery pack. Those dimensions are the internal cell only measurements the foam, HDPE, and steel will add 1.5-2" per dimension for an overall battery pack size. Now I plan to have this in a foam lined HDPE box embedding in a steel box for protection and support. The terminals will exit the pack such that the battery leads the controller plus the controller leads to the motor will be significantly less than 1 meter to minimize voltage drop. All the cells are new and measuring 3.43 or 3.44V. I will be checking them all before assembly, and if I need to running them all through a discharge and charge cycle to test and match them all before assembly.
Should I replace the stips I plan to use? Will I need to replace the connections between cells with copper? How thick if I do? Can anyone offer suggestions for a first time battery pack builder? Your suggestions and help would be greatly appreciated, thank you.
