The modular-designed accumulator box containing the Li-Ion accumulators is positioned in the SEABOB’s bow and is incredibly robust and absolutely watertight. Quick charging the SEABOB from a mains socket takes only approx. 90–110 minutes. The SEABOB CAYAGO VX2 and SEABOB CAYAGO F7 models are equipped with an Accumulator Change System (ACS). For external charging, the accumulator box is easy to remove and reinsert. The ACS makes changing a fully-charged second box quick and easy. And your SEABOB is ready to take to the water again.
