Depends if you care about longevity...

  True, but charging while too cold can also damage the cells in ways that are not immediately visible and that in turn might trigger thermal runaway rather than just cell capacity degradation. That's because the cells on the outside of the pack will likely be much later to the party than the ones on the inside during charging. But any good BMS will simply refuse to charge as long as the pack is too cold.
