If you want to use a 3.2V lithium iron phosphate battery to form a 12V/80A battery, follow these steps:
1. The voltage is sufficient, 4 3.2V in series is 12.8V. First, use 4 batteries in series
2 to meet the capacity, 20A and 4 batteries are 80A. 4 groups of 4 batteries in series are assembled
3 In other words, a total of 16 batteries are required
4. are in parallel. Stand up
