Not Balancing Three 12v Right
This post is just for info in case anybody else has a similar situation I have learned the truth about wiring up three 12s as though they were two 12s. With the load and charging pos and negs o...

Exercise: 24 batteries 12 in series for 24 volts, parallel bank. This is where things get critical.
pnichols hit the nail on the head, and guess what?
A millohm meter is USELESS when it comes to verifying the integrity of such a setup.
A carbon pile load tester + accurate ammeter and accurate voltmeter is the only way to "balance" such a system with a faintest hint of accuracy.
Harbor Freight has an inexpensive 500 ampere load tester. Ignore its instrumentation, utilize the variable load. By factoring voltage and amperage VA a person can get serious about balancing a complex bank.
If I HAD to do a 3-bank system without this setup I would use lead coated copper terminals, and seal the heck out of exposed conductors.
