PT100 Battery Guard - 100 Amp 12/24V

The Alfatronix PowerTector PT100 is a 100A solid state battery guard designed to protect your vehicle’s starter battery from deep discharge. By monitoring the source voltage, the PT100 automatically disconnects non-essential loads if the battery voltage falls below a pre-set level, ensuring there’s always enough power left to start the engine.

Unlike traditional mechanical isolators, this solid state unit has no moving parts, making it silent, durable, and resistant to vibration—perfect for demanding automotive environments. The PT100 also helps extend battery life by preventing over-discharge damage.
