About This

PRODUCT PARAMETERS: Board Size: 57 x 42 x 19 mm (2.24 x 1.65 x 0.75 inches) LxWxH; Input Voltage: DC 12-36V; Accuracy: ±0.1V; Power Consumption: <1.5W; Maximum Current before Breaker Trips: 20A
PRODUCT FUNCTION: A programmable low-voltage disconnect switch designed for DC 12–36V lead-acid and lithium-ion batteries. This module provides battery protection by disconnecting loads when voltage is too low. Batteries are not included. Compatible with lead-acid, lithium-ion, and solar storage batteries. Not suitable for assembled battery packs.
PROLONGS BATTERY LIFE & ENSURES SAFETY: Automatically cuts load at low voltage to stop deep discharge—safeguarding battery health and extending service life.
HIGH-PRECISION VOLTAGE CONTROL: Protect your battery with ultra-accurate (0.1 V) monitoring and automatic cut-off between 12-36 V—compatible with lead-acid and lithium batteries.
MEMORY FUNCTION: Even after a power failure, the module automatically restores the last saved settings, eliminating the need for repeated adjustments.
NOTE: This voltage protection module uses a compact PCB design with a mini relay and slim circuit lines. For safe operation, the recommended working current should not exceed 8A. The maximum supported current is 10A at voltages below 12V, and should be kept under 8A when above 12V to avoid relay damage.
