Hi all I need a pump to circulate gas from the top of my batteries to the bottom in order to eliminate acid stratification during charging in order to shorten the charge time and lower the temperature, I have 12 x 2 volt cells about 600 mm deep, currently I need to over charge in order to promote gassing to adequately mix the electrolyte, a pump would reduce this by 20 to 30% so could be well worth it if I can find a pump to do the job, thinking along the lines of aquarium air pumps but know nothing about them, looked at battery guys but prices are stupid, thing is the air in needs to be from the cells and not from fresh, any ideas?
