Can the hoodie be used while charging?
If you mean charging your battery, no, you are not able to use the hoodie while charging the battery as both require use of the same 7.4V input/output port. You can, however, use your hoodie and charge your phone at the same time.
Would it be unsafe to use a battery with a lower volt rating? I realize it might not be as hot.
