Hi,  
I’m doing a major EV project and building the battery pack for it. The project uses A123 cylindrical cells in a 15S32P config. Any ideas on how the most efficient way to connect the batteries together? For the 32P should I use nickel tabs or is a plate possible?  
Really new to this and would appreciate any suggestions.thanks
