Re: Got 4Ah, not 5Ah, battery 18V (20V) - done right thing?

When sizing a "battery bank" endeavour to use the highest capacity
cells you can get, connected in series, rather than higher voltage
batteries connected in parallel - for a 36 volt pack use 6 big 6 volt
batteries in series rather than  2 packs of 3 12 volt batteries. The
6X6 is ONE BATTERY while the 6x12 volt solution is actually TWO
BATTERIES in parallel - with the associated load sharing and
interconectivity issues involved.

I've seen that advice several times and priced it out, finding that 12V 100Ah appears to be a sweet spot for price vs performance, in lead-acid and lithium. Perhaps it would be different if I needed more than 50A from the batteries.
