I'm assembling a portable kit in which I can fit two small sealed
lead-acid batteries.
For my specific size requirements, I have the option of putting (2) 12v
(3.0Ah) batteries in parallel, or (2) 6v (3.0Ah) batteries in series to
obtain the 12vdc I need. (the specific batteries I am considering are
the PowerSonic PS-1230 - Mouser # 547-PS-1230 or the PowerSonic PS-630 -
Mouser # 547-PS-630)
It seems to me that with [ 2 x 6v (3.0Ah) = 12v (3.0Ah) ] while [ 2 x
12v (3.0Ah) = 12v (6.0Ah) ]. Maybe the simplicity of this makes me
question this assumption, or maybe it's been too long since I did these
kinds of calcs ;-)
Could someone please confirm or deny my thoughts here?
Also, I'm trying to calculate (roughly) the useful battery capacity
based on considering the minimum current draw from a rig, and the
maximum current draw from the same rig. For example, given the battery
configurations above, and considering the K2 approximate minimum current
draw of 150mA and approximate maximum current draw of 2A (at 10w), what
is the potential operating time ranges available from the batteries?
Thanks in advance & 73,
