[PSUBS-MAILIST] battery compensation

[hank pronk via Personal_Submersibles]

Alan,I have figured out a way to use AGM batteries with oil compensation and NO need for 2psi relief valves.  The rubber bladder on top can act as a pressure source.  Just size the membrane to create tension by over filling with oil.  Might work, but I am not sure what the benefit would be by using AGM's -they are actually heavier than lead acid.Hank
