Changes

One should refrain from adding new batteries to an already used set as it wears down the old batteries faster. This will result in deep discharged old batteries. Therefore, we could consider moving the current/old set to our future octagonal cabins. As depicted in the illustration above, we could run two independent 12 V systems in different locations. Rolls Battery released a new version of our current batteries, the S12 185 ([data sheet](https://www.rollsbattery.com/battery/s12-185/?pdf=8512)). Here is a [summary of the model updates](https://rollsbattery.com/wp-content/uploads/2019/05/Model-Updates.pdf).

We are trying to implement a wireless Arduino-based system that switches on the fridge when the battery voltage is high enough.

We have [long-run antennas](https://www.amazon.com/gp/buy/thankyou/handlers/display.html?ie=UTF8&asins=B06WLH4ZG6&isRefresh=1&orderId=113-1514855-6645050&purchaseId=106-6720613-8120221&ref_=chk_typ_browserRefresh&viewId=ThankYouCart) for wireless communication.
