Charging a 7.4V rechargeable battery pack using a solar cell that outputs only 2V is feasible by employing a boost topology DC-DC converter. This type of converter steps up the lower voltage from the solar cell to a level sufficient to charge the battery pack. The discussion confirms that utilizing a boost converter is the definitive solution for this scenario.

Thanks!
