Dual-Battery-Monitor BM2000, 12V or 24V stand-mount version The dual battery monitor is ideal for the continuous monitoring of 2 separate batteries (starter and consumer battery). Available for 12 V dual-battery systems or 24 V dual-battery systems as a surface-mounted version for off-road vehicles or motorhomes. Nakatanenga has the exclusive distribution rights for the dual battery monitor in Europe. The digital technology used in these monitors makes it possible to accurately reproduce the non-linear characteristics of lead-acid batteries. Using the green button in the centre, you can switch the information output on the display from one battery to the next. The dual battery monitor emits an audible alarm/tone as soon as the battery is either overcharged (14.8 V and above) or over-discharged (12.2 V and below).  The dual battery monitor has been specially developed to be combined with the Cyrix-ct intelligent automatic cut-off relay. Link function: If you press and hold the green button on the dual battery monitor for 10 seconds, both batteries are forcibly connected in parallel for a few minutes, which is particularly useful when operating a winch or when the starter battery is too weak (only possible in combination with the Cyrix-ct cut-off relay). Features:  Warning in case of overcharging or excessive discharge  reverse polarity protection   Audible alarm (can be muted)  Energy-saving functions (automatic dimming of the screen depending on the ambient light, automatic sleep function = auto-sleep 10-30 minutes after the battery stops running) 3 m long cable  Operating elements summarised:Single button press (green button) = Change information output (from battery 1 to battery 2)  = Mute active alarm.Press and hold button for 3 seconds = Switch alarm off/on permanentlyPress and hold button for 10 seconds = Link function: Switch batteries in parallel for 30 seconds via the separately available cut-off relay (jump start) -> Only possible in combination with the Cyrix-ct cut-off relay Alarm function: - Level 1 = as soon as 14.8 V (29.6 V) is exceeded or 12.2 V (24.4 V) is fallen below: beeps every 10 seconds, screen lights up - Level 2 = as soon as 15.0 V (30.0 V) is exceeded or 12.0 V (24.0 V) falls below: beeps every 1/2 second, screen lights up -> as soon as the alarm goes off, you can mute it by lightly pressing the green button Specifications:  Dimensions: 69.5 x 50.5 x 20 mm (surface-mounted version) ; 85.5 x 66.5 x 20 mm (built-in version) Weight: 130 g incl. cable  Low-voltage warning: DC voltage below 12.2 V (24.4 V) Over-charge warning: DC voltage above 14.8 V (29.6 V)  

Electronically operated relay for simultaneous charging of two batteries (e.g. starting- and board-battery). The relay is installed between the two batteries, it stays disconnected until one of the batteries reaches a predetermined voltage level. Now the relay connects the two and both are fully charged. This method ensures that even when only using the vehicles for short distances, the starter battery is always ready to go. Additionally, the Cyrix-ct software monitors the tendencies of the voltage levels and then optimizes the delay accordingly.   12/24 V Automatic: The Cyrix-ct relay automatically recognizes the voltage and adjusts the output. Heat protection: The Cyrix disconnects when he recognizes temperatures exceeding the optimal operating temperature and shuts off accordingly, the relay connects automatically once the temperature has fallen again.   Once you turn off your motor and the alternator no longer charges the batteries, they are automatically disconnected to spare the starter battery for when you want to get going again. As soon as the voltage falls, the relay allows for a short delay in the disconnect to keep the batteries from overloading. The Cyrix-ct operates based on past charging patterns and only deviates from these when changes to this pattern appear within a certain interval. The duration of the delay depends on the pattern of deviation in voltage.   Technical Details:  Operating voltage (automatically): 12 V / 24 V Peak Power: 300 A Constant Power: 120 A  Tightening voltage: from 13 V to 13,8 V and 26 V to 27,6 V with intelligent disconnect Abfallspannung: Von 11 V bis 12,8 V and 22 bis 25,7 V with intelligent disconnect Power consumption when disconnected: <4 mA Power consumption when connected: 12 V: 220 mA ; 24 V: 120 mA Wire bolts: M6 Measurements: 46 x 46 x 80 mm Protection: IP54 Weight: 150 g   Connecting (V) DELAY   Disconnecting (V) DELAY V < 13 V Stays open   V < 11 V 0 s 13,0 V < V < 13,2 V 10 min   11,0 V < V < 12,0 V 1 s 13,2 V < V < 13,4 V 5 min   12,0 V < V < 12,2 V 10 s 13,4 V < V < 13,6 V 1 min   12,2 V < V < 12,4 V 30 s 13,6 V < V < 13,8 V 4 s   12,4 V < V < 12,8 V 3 min       >  12,8 V Stays connected       >  16 V Overload prevention

Banner's Running Bull series is the perfect battery for any offroad vehicle. With its modern AGM (absorbing glass mat) technology, the Running Bull offers a wide range of features tailored to the 4x4 market The battery acid is bound in fiberglass wool - preventing it from spilling, even at extreme angles The limited self-discharge makes it perfect for vehicles not in use every day The battery is cycle proof, allowing it to be charged and discharged even more often than a regular car battery, lengthening its lifespan Even hour-long gravel roads and all the vibration that comes with it do not affect the functionality The battery case is sealed, thus there are no vapors and an installment inside the cabin is possible The battery is deep discharge proof, allowing it to be discharged for an extended number of times whereas normal batteries would suffer after only very few of those instances It is also capable of high currents allowing it to provide electricity fast and with high voltages without sustaining any damage! This is especially useful when operating a winch or a large entertainment system Even in low temperatures, the battery will deliver up to 900 A, this way you do not have tomorrow whether your 4x4 will run or not. Allowing for carefree use even in times of high tech interiors.  Depending on the desired capacity, mounting spot and configuration you can choose from a variety of options to fit your needs. Concerning the Defender: It is possible to mount any of the battery models up to 105 Ah underneath the driver's seat. When choosing a two battery system it is even possible to mount two with the capacity 80 Ah each - that's why we recommend our 160 Ah dual battery system, shipped ready to install with the amount and our intelligent battery management system. If one really wanted to, even two 92 Ah batteries could be installed underneath the seat, but this is a very time-consuming process and we do not recommend taking this approach.
