HOOTS WLAN Battery Guard
HOOTS battery monitor with WiFi for 6V 12V 24V
HOOTS BATTERY was specially developed according to customer requirements and is an innovative tool for battery monitoring of 6V 12V 24V vehicle batteries. In addition to the battery voltage, the power consumption in amperes as well as humidity and temperature can be measured and saved. This means you can keep an eye on all important data if your car is parked for a long time. Optionally, the WLAN Battery-Guard automatically warns when limit values are reached via email or push. This means there will be no more unpleasant surprises the next time you try to start.

Which radio connection do I need?
HOOTS BATTERY is set up and the live data is displayed via Bluetooth. The stored data is sent to the BATTERY Cloud via WLAN.
How is HOOTS BATTERY installed?
HOOTS BATTERY is installed between the ground terminal (negative terminal) of the battery and the ground point (black/brown ground cable) on the vehicle.
In addition, a cable is attached to the positive pole of the battery using a cable lug. Suitable mounting material and optional connection options can be purchased in the shop.
IMPORTANT: HOOTS BATTERY must be installed in front of a circuit breaker / main switch and be permanently connected to the positive and negative poles of the battery.
Does HOOTS BATTERY have reverse polarity protection?
Yes, but if you swap the negative and positive poles, the device will not work.
Under no circumstances should you mount the negative pole and the positive pole at the respective ends of the copper shunt!
How long can the data be stored?
You can view the battery data for up to 3 months in the data cloud free of charge.
Is an additional power supply necessary?
No, HOOTS BATTERY is powered by the battery. The current consumption is only 20 MüA, so the battery is not discharged.
Which batteries is HOOTS BATTERY approved for?
For all vehicle batteries from 6V, 12V to 24V. Both lead,
Gel, or AGM batteries can be monitored. Li-ION batteries can also
be monitored.
What is the quiescent current of the HOOTS BATTERY system?
The battery monitor has a monitoring mode with a current consumption of 0.3 mA.
Battery monitor 12 V shutdown with HOOTS BATTERY?
Security system: It is not possible to switch off the vehicle battery remotely, but HOOTS BATTERY will show you the WLAN status. If the vehicle is no longer connected, it has either been removed or the WiFi is not working.
Can I read the battery parameters without WiFi?
Yes, via Bluetooth.
Monitoring the battery charger/maintenance device with HOOTS
HOOTS BATTERY also works with a connected battery charger or battery maintenance device such as CTEK. You can safely monitor the battery charging process (volts, amps, temperature) remotely via WiFi or monitor/control the charger on the vehicle via Bluetooth.
Can I also use HOOTS BATTERY with a circuit breaker / main switch?
HOOTS BATTERY also works with circuit breaker / main switch. However, the circuit breaker must be connected after the HOOTS BATTERY system. As long as HOOTS BATTERY has a direct connection to the negative and positive poles of the battery, you can continue to use it
Measure battery voltage (volts), device temperature and humidity even with the circuit breaker flipped.
What current load is the HOOTS BATTERY measuring shunt designed for?
HOOTS BATTERY is designed for a permanent current draw of 200 amps or a short-term load of 5 seconds with 1000 amps.
What power consumption occurs when transmitting system data via WLAN / cloud?
The system briefly requires 20 mA to transmit the system data to the cloud or to the WLAN network.
Can the HOOTS BATTERY also be connected to the high-voltage network of an electric vehicle?
No, commissioning in the high-voltage electrical system is expressly not possible and will result in damage to the battery monitor and possibly a defect in the vehicle.
Can I also use HOOTS BATTERY with built-in battery terminal clamps or clamp clamps?
As long as HOOTS BATTERY has a direct connection to the negative and positive poles of the battery, you can continue to use it
Measure battery voltage (volts), device temperature and humidity.
We recommend using circuit breakers/main switches for this.
