Low Voltage Cutoff Board v1

Description

Features

• For 12V lead-acid batteries, or equal nominal 12V batteries.
• 6V – 15V.
• Cutoff and cut-in based on R1 to R4.
• Backside Ground Plane: For reduced noise emissions and optimal signal strength.

Create a circuit that cuts off the drain of the lead-acid battery at a certain voltage, decided by R1 and R2. Cut-In decided by R3-R4.

With R1 and R2 you create a voltage divider.  If the voltage just between those two comes below 1.66 V, it will cutoff.

With R3 and R4 you decide when it should turn on again. If the voltage between those two rises above 3.33 V, it turns on again.
