Having spare batteries to run your dive light has some major advantages. If you are planning to go on a live-aboard dive trip they are a must. Keep diving with freshly charged spare batteries and experience no downtime between dives, because you have to wait for your battery to be quickly charged. The Bigblue battery packs have you covered for whatever model BigBlue you may own. All battery packs use quality lithium-ion battery cells.
