Building a 12V 110Ah battery bank using 80 32650 LiFePO4 cells


Kerry Wong built a DIY battery bank using eighty 32650 LiFePO4 cells:

During the past couple of weeks I have been busy making a large battery bank using the eighty 32650 LiFePO4 cells I bought on eBay. The battery bank I am building is a 12V (13.2V nominal) 4S/20P one. With each cell rated at 5.5Ah the battery bank has a capacity of 110Ah, which is just under 1.5kWh.
While These cells are marked as 32700 they are technically still 32650 cells according to the datasheet, which is a little bit confusing. Since I am making a custom battery bank the actual cell dimension is not as critical.
