Vaira Battery Bank SoilCO2 |
I checked the water in the soil co2 battery bank. The water levels were low exposing the plates but these batteries didn’t take that much water – about a gallon to fill all of them. |

I installed new batteries (borrowed from DWR) for the new soil co2 system. The original batteries were killed because they were wired for 24V and the solar for 12V. |

Initial installation of the VR_soilco2 battery bank. Two pairs of deep cycle batteries were installed for a 24V system. However the solar panels were only wired as 12V and bled the batteries dry. |
