Paul,

I also have a Pro 6.  I have been thinking of increasing the negative 
buoyancy of the unit.  However, filling with epoxy may not be the best 
solution.  Before doing that, you should weigh the epoxy and calculate it's 
density and the space available.  You might find that you cannot develop 
sufficient ballast with straight epoxy.  You might try mixing lead shot 
with epoxy in order to increase the mass.  The plastic used in the Explorer 
lights is quite slippery.  It would be best to check with EE as to what 
adhesives will stick to the polyethelyne.  I have been thinking of adding 
some lead to the unit, either on the inside or the outside.

Another aspect to consider is heat transfer.  If the lower section of the 
cannister is filled, there may be less than desirable air flow during 
charging operations.  In other words, the battery might become overly warm 
while charging.
