Don't tap off various voltages. Use DC-DC converters for any voltage
other than nominal. Anything else will lead to uneven charging and
shortened life.<br>

<div>I have a battery bank questions. 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?</div>
