Battery Guardian
(BG)
The Battery Guardian allows you to remotely disconnect the vehicle from the battery. Prevents battery drain during storage while eliminating the cumbersome task of physically removing the battery cable from the bank of
batteries. Automatically disconnects the vehicle from the battery if it senses low voltage condition.
Product Features and Function
The Battery Guardian draws no current in the On or Off state.
Current Ratings:
160 Amps continuous, 600A cranking. (Part # 00-10041-300)
225 Amps continuous, 1200A cranking. (Part # 00-10041-350)
Ignition proof: SAW J1171
Waterproof: IEC 60529, IP66 IP 67, ASTM B 117 96 hours salt spray
Approved for battery compartments
Microprocessor-controlled internal coil:
No external fuse
Prevents coil damage from “sticky switches”
Prevents accidental disconnect if ignition signal is detected
Weight: Under 1 pound
Operation:
The Battery Guardian opens and connects the two 5/16” copper terminals by means of a sliding contact. Each time the Sig terminal is momentarily switched to ground, the contact instantly switches, and the Battery Guardian changes the ON/OFF state. The Battery Guardian remains in the On or Off state, without coil power.

BG Series
– 160 AMPs

– 225 AMPs

Note:
The BG is a Battery Disconnect (BD) but also includes an automatic low-voltage disconnect. When it senses the levels are getting low it will automatically disconnect to prevent further draining.
(Lithium) LI-BGA Series
The Battery Guardian Auto allows you to remotely disconnect the vehicle from the battery. Prevents battery drain during storage while eliminating the cumbersome task of physically removing the battery cable from the bank of
batteries. While in BGA mode, automatically disconnects the vehicle from the battery if it senses low voltage conditions, but with owner override capability. Automatically re-connects the vehicle to the battery if it senses a charging voltage condition.
Product Features and Function
The Battery Guardian Auto draws no current in the On or Off state.
Current Ratings:
160 Amps continuous, 600A cranking. (Part # 00-10041-400)
225 Amps continuous, 1200A cranking. (Part # 00-10041-450)
Ignition proof: SAW J1171
Waterproof: IEC 60529, IP66 IP 67, ASTM B 117 96 hours salt spray
Approved for battery compartments
Single wire operation
Microprocessor-controlled internal coil:
No external fuse
Prevents coil damage from “sticky switches”
Prevents accidental disconnect if ignition signal is detected
Weight: Under 1 pound
Operation:
The Battery Guardian Auto opens and connects the two 5/16” copper terminals by means of a sliding contact. There are 3 states, Off-Disconnected, On-Disconnected, and BGA-Connected with Auto, whereby the device will disconnect when it senses low battery, and reconnect when it senses charging. Cycling the switch Off & On will also reconnect the relay. The Battery Guardian Auto remains in the On or Off state, without coil power.

Note:
The BG AutoSelect is a cross between a BD and a BG and works with a 3-position Rocker Switch: On, Off, and Auto.
In the On or Off position, it works like a BD. In the Auto position, it works like a BG.
