Check out the load testing video below and be sure to read all about Kerry Wong’s process (and courage, frankly) here.
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.
Once I finished building the battery bank, I ran some load tests to ensure that the batteries and the BMS module are working properly. The video below shows me putting the battery bank through its paces.
