The fully charged voltage of a single lithium iron phosphate (LiFePO₄) cell is 3.65 V. Formula for calculating the number of strings: Number of strings = Full-charged battery pack voltage ÷ 3.65 V Example- 48 V battery pack: 48 ÷ 3.65 ≈ 13 strings (actual 13 × 3.65 = 47.45 V).- 60 V battery pack: 60 ÷ 3.65 ≈ 16 strings (actual 16 × 3.65 = 58.4 V). Remember: 18.25 V indicates a fully charged LiFePO₄ battery pack with 5 strings (3.65 V × 5).

  The fully charged voltage of a single NCM/NCA cell is 4.20 V. Formula for calculating the number of strings: Number of strings = Full-charge voltage of battery pack ÷ 4.20 V Example- 48 V battery pack: 48 ÷ 4.20 ≈ 12 strings (actual 12 × 4.20 = 50.4 V).- 60 V battery pack: 60 ÷ 4.20 ≈ 14 strings (actual 14 × 4.20 = 58.8 V). Remember: 21.0 V indicates a fully charged 5-string NCM battery pack (4.20 V × 5).
