I always thought that a very small 12V or 24V tap relative to the total capacity would be inconsequential. I was recently told otherwise by a battery mfr rep, but that is not surprising. I suppose the real question is what constitutes inconsequential. A 1A @ 12V fan on a 1000aH @48V battery bank can't make any real difference. Correct me if I am wrong!

I have an Oil & Gas client interested in setting up an off-grid control system that has a various DC loads at 12VDC, 24 VDC and 48 VDC. My thought is to build a 48 V battery bank and tap off the bank at various points to create a 12V bus, 24V bus and 48V bus. I am a bit concerned about unequal loading of the batteries. Has anyone dealt with something like this that would like to share some insight? Thanks -- Mac Lewis "Yo solo sé que no sé nada." -Sócrates
