6v Batteries in Series or Parallel Configurations

6v batteries in series or parallel configurations

Alternative forms of energy, like solar, are rapidly gaining ground. Its easy to get confused when you’re trying to figure out what batteries you need, then how to deploy them in your desired implementation. This is how you can wire 6v Batteries in Series or Parallel Configurations to get the desired voltage and capacity.

You’ve got your solar panels, your inverter and your batteries, now what is the best way to connect those deep cycle batteries together, to get the power you need?

Batteries wired in Series

When you wire batteries in series, the voltage is doubled, but the capacity (amperage) remains the same.

Here are 2 6volt batteries, each with 370 Amp Hours (Trojan L16E-AC Battery). The output of these 2 batteries wired in series would be 12v and 370AH.

Volts X Amps = Watt Hours

12v x 370 amps = 4440 Watt Hours

4440 Watt hours equates to running a 100w DC television for 44.4 hours. You never want to run your batteries to 0% charged though, anything less than 50% can be battery killing, depending on the battery, it’s design and other factors.

Batteries wired in Parallel

When you wire batteries in parallel, the voltage remains the same, but the capacity (amperage) is doubled.

Here are 2 6volt batteries, each with 370 Amp Hours (Trojan L16E-AC Battery). The output of these 2 batteries wired in series would be 6v and 740AH.

6v X 740AH = 4440 Watt Hours

Series/Parallel Combination

When you wire batteries in a series/parallel combination, the voltage is doubled, and the capacity (amperage) is doubled also.

Here are 4 6volt batteries are connected to form 2 banks of 12volts, each with 370 Amp Hours (Trojan L16E-AC Battery). The output of these 4 batteries wired in series/parallel would be 12v and 740AH.

12v X 740AH = 8880 Watt Hours

Parting Battery Recommendation

When it comes time to buy your deep cycle batteries, you should seriously consider Trojan Deep Cycle batteries, like the Trojan L16‘s (made for industrial floor scrubbers). They cost you more money up front, but should last much longer than regular automotive/marine batteries, that claim to be “deep cycle”.

This is a picture of the last 2 Trojan L16‘s I picked up for our rural solar project. They weigh over 100lbs each, are 6 volt and 370 amps.

  1. This was my first visit at this wеb site, and this post was very fruitful for me. I was unsure of the differences between serial and parallel wiring for my solar batteries. This post made thing “click” for me. Total epiphany! Thank you so much.
