Just a quick note on battery health and how to avoid costly replacement by utilizing a very powerful circuit gadget!
The low Voltage disconnect can really save your power bank form catastrophic failure which can even ruin solar charge controllers or solar panels and inverters if not noticed in time!
As we know most batteries are 12vdc , yes I know about the 6vdc Trojan golf cart batteries but let's stay focused lol
where were we , oh yes, 12v batteries!
depending on the chemistry of the battery, for this example we will use a Flooded or Lead Acid battery most commonly found in your vehicle. these batteries are used to start the vehical and once it's started the alternator charges the battery as well as provides power to the vehicals electrical needs.
please note:
These batteries are charging constantly at 13.8vdc to 14.5 or even higher if the batteries were very low in charge!
Once your Vehical is switched off, the battery voltages will fall to whatever the cell rest at, ideally 12.6vdc or higher
You can load test your batteries to know as to how they will respond under a load however these testing instruments differ from battery chemistry and loading a solar AGM battery with a max 30Amp output with a load tester from a 1000+ CCA Flooded Battery you risk both the test equipment and the battery as it's not rated for those amperage.
If a Flooded We Lead Acid battery's voltage is taken too low, the cores or metal plates inside the batter can become corrupted and or fail completely. This is where the low voltage disconnect comes in to save the day!
Should you leave a fan on or transfer pump whatever is POWER SUCKING your circuit, have no fear, you can set a voltage on the device, this is done with some wiring and whatnot with the inverter, for example, and now you have a circuit that will break the connection from the battery to that inverter once the core voltage is lower than the value you specified.
so let's say instead of 11.9vdc we wanted out 2000watt inverter to disconnect at a higher voltage like, 12.2vdc or 12.4vdc
Why would this mater? well maybe you know that once the voltage is too low, that large inverter is connected to heavier power consumption devices just won't work and "trying" to use them with low power could again ruin the electrical component in either the inverter or whatever the device is you wish to power.
In conclusion for the sake of a $30-60 component that could keep your batteries fresh as the day you sawed off the arm and leg to buy them, it's worth it! hope it helps keep your lights shining brighter!
