For instance DPV and lights generally use 24 volts so why can't we "manifold" the power together? Scenario: you're waaay back in a cave and your DPV battery dies. Do you really need that 50 watt light more than DPV run time, especially with a buddy? Wouldn't it be nice to be able to unplug the light head and attach the light battery to the DPV, whip out one of your backup lights and get thee to a nunnery? Likewise, if you got a low batt indication on a computer wouldn't it be nice to just tap into your light or DPV? I've seen the power cables that you can plug/unplug underwater (not while under power though) in the Dive Right catalog so maybe we're not that far from being able to do this. All we need now is for the manufacturers to standardize input/output plugs and voltages. Will next generation divers carry a spare battery and cord (along with a spare light head or two in a pocket) that would allow them to address virtually any battery failure? Watcha think?
