Battery FAQs |
When adding batteries together in series, you can't add both voltage and current
(if you do that is multiplying them together, not adding).
Mounting batteries in series adds the voltage but does nothing to the
current capacity (it does increase the power, of course).
Take four 6v 210AH batteries... (6 x 210AH = 1260 Watt-hours each x 4
batteries = 5040 Watt-hours for all four))
1. Connect them in series you get 24V at 210AH (24 x 210 = 5010 Watt-hours)
2. Connect then in parallel you 6 x 840AH = 5040 Watt-hours.
3. Connect them two in series and then the two groups in parallel = 12V x
420AH = 5040 Watt-hours
Not matter how you connect the four batteries, you will not get more than
5040 Watt-hours...

Sam's Club GC-2 (Golf Cart) Batteries made by Exide. Most small
systems could start with this cheap learning battery.
I had 8 in my small home system for over five years and then still work
great in our shop powering up inverters and systems being tested for
customers. I still have 4 in my RV, and they work
great.
