Our small installation will be 12 volts meaning we need a battery with 305 amp hours. To produce a 12 volt output two 6 volt deep cycle batteries must be wired in series positive to negative.

How to make a 12 volt battery bank. Below is a collection of quick reference diagrams on hooking up multiple 6 volt and 12 volt batteries to create 6v 12v 24v 48v etc as required for energy storage systems commonly found in residential and off grid solar hydro and wind systems. Make your battery pack by series or parallel connection. Choose your system battery bank voltage. Click 2 4 6 or 12 volt batteries to build your battery bank. You have to connect the cells in parallel to reach the desired capacity mah and connect such parallel group in series to achieve the nominal voltage volt. If you need a 12v battery and want to learn how to make it from 18650 cell watch the video it has details on how to make a new battery at homeyou can make this battery from 18650 cell that can be.
Off grid solar installations can be 12 volt 24 volt or 48 volt the voltage you choose depends on your installations size location and layout and needs. Simply hook up the 12 volt dc adapter to the battery bank by placing the red clamp on the positive terminal of battery 1 and black clamp on negative of battery 2. You can then connect each 6 volt pair in parallel with another pair to create a larger 12 24 or 48 volt battery bank. Discharging and see the mah of each battery. Match them to closed capacity. This is called a series parallel configuration.
Select the closest amphour rating for 1 battery. From there plug in your dc voltmeter and take your reading. Your inverter input voltage select the size of the battery bank capacity in amphours. Each 6 volt battery pair operates as a single 12 volt battery. To make the battery pack you have to first finalize the nominal voltage and capacity of the packeither it will be in term of volt mah ah or wh. The important steps when making a 12v battery.
Parts needed for this project. Newer batteries check the sticker date that are not used should have a relatively high reading 125 127.
