Discharge protection for 12v 30a batteries

Battery protection 12V max 30A

Model features: POLISH product, has an LED indicator for turning on the receiver and an emergency button for turning on the receiver. It has small dimensions and minimal voltage drop (below 0.1V) from the battery to the load!

.

The module protects the 12V battery against too deep discharge. The protection controls the battery voltage so that it does not discharge below 10.5V. When the battery reaches the voltage limit of 10.5V, the protection will disconnect the receivers from the battery. The protection frees you from the obligation to constantly monitor the battery so as not to discharge it below the voltage recommended by the battery manufacturer. A battery discharged below 10.5V loses capacity and charging cycles The protection can be used with all 12V batteries (gel, lead, etc.).

.

The maximum current consumption by the receiver from the battery is 30A.

.

Connection:

- red: +12V battery

- black: - 12V battery

- blue: positive output (+12V) to the receiver

.

i.e. according to the diagram:

The protection should be connected as close to the battery as possible, preferably to its terminals. As you can see, the receiver is controlled from the plus side of 12V.

.

Principle of operation:

We connect the receiver that we want to power from a 12V battery to the protection according to the above diagram and then connect the protection to the 12V battery. If the battery voltage is above 12.1V, the protection will turn on automatically. If the battery voltage is lower (but higher than 10.5V), the protection is activated by pressing the button. The green LED will light up. From this moment on, the receiver is powered by the battery. During operation, the battery voltage will drop as it discharges. When it drops to 10.5V, the protection will disconnect the receiver (the LED will turn off) preventing excessive battery discharge.

.

The protection will be turned on again:

- automatically when the battery voltage is above 12.1V (the battery is charged or changed)

- manually with the button, provided that the voltage on the battery increases above 10.5V.

.

.

Switching on with the button (emergency) is helpful when, after the battery has been discharged and you have waited some time (when the battery has regenerated to some extent and the voltage on it has increased slightly) we must turn on the receiver by powering it from the same battery.

.
