We run 2 poles, 2x100m microbore hose, 1 di unit from 1x100 psi pump and one battery with no flow control, no split charging & no problems whatsoever for the last 6 years.
What is the amh on your battery? Has this set up ever run the battery flat?
Quote from: rich fraser on July 31, 2011, 12:15:15 pmWhat is the amh on your battery? Has this set up ever run the battery flat?It's two x 55Ah batteries in parallel, so 110Ah in total. The double battery is standard on the van and everything runs direct from those, so no leisure battery.I've not run the battery flat at any point, though two man working only started a month ago, so I don't know whether winter might have an impact. We are doing nine or ten hour days most times.VinIt's not so much the AH but the ability of the battery to cycle. A leisure or deep cycle battery can be cycled (fully charged to fully flat) up to 1,000 times depending on quality and spec. A car battery isn't designed to be drained continuously. They usually are just to provide high starting ampage and a drop of about 10-15% in capacity that's then quickly recharged by the alternator to 100%. By this then the battery doesn't really cycle at all. If you do completely cycle a car battery it can normally last about 10-15 cycles.
