ProMax 12-Volt Heavy Duty PriorityStart! Automobile Battery Protector / Electronic Cut Off Switch This is a low voltage disconnect controller for your 12v battery.

EV's are often parked for long periods off season. EV's with 12v batteries have the batteries drain down and then cannot "start" the EV even though the high voltage pack is fine.

THis device sits between your 12v aux battery and the system. Anytime the voltage falls below some set level, it disconnects the battery entirely, preventing further discharge.

If the battery is charged later, then there is also a user configurable voltage for the reset of this device.

An inexpensive guardian for your 12v aux battery. Micro-processor controlled
