Webwelding current and a shunting current, I W and I S, respectively. These two currents, and therefore the amounts of heat, are de-termined by the relative values of the re-sistances along the shunting and welding paths. An estimate of these resistances is helpful for assessing the amount of elec-tric current and, therefore, heat, diverted WebMar 4, 2024 · By the use of cell balancing, every non-defective cell in the battery pack should be balanced to the same relative capacity as the other non-defective cells. Other than using cell balancing, you can keep the pack cool since heat is one of the primary factors that lead to thermal runaway. This minimizes the retention of heat in the pack. crypto fomo index
