Does anyone know if LifePo4 750 mah rcr123a 3.0 volt batteries will fit in the WOW. I emailed customer service last week asking this but have gotten no response yet, on the support page under "My tickets" it says my question has not been assigned yet. I would really like to order a Wow but want to make sure my batts work or if I should get some from them. Is their customer service always this slow?
