HBC Doppelbatteriemonitor, 12/24 V als Aufbauversion oder Einbauversion 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) screws and a template with the distances of the necessary drill holes are included with the built-in version 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)  

Complete set Nakatanenga dual battery system 160Ah for LR Defender Nakatanenga's dual battery system for the Land Rover Defender 90/110/130 offers a high capacity, revolutionary AGM technology, safe and simple battery management, high output in electricity when using a winch, for example, and the security to start your vehicle even on a low charge while using a freezer or that large HiFi-system. The system easily installs underneath the driver's seat of your Defender. The black bracket holds the two 80 Ah AGM batteries from Banner in place. These batteries a resistant to vibration and thus can not spill, e.g. in case you roll your 4x4, they're also protected from deep discharge and capable of a very high output. Since they are spill-proof they also do not release any vapors and even deliver in very cold temperatures. All while not affecting the mechanism of your seat. The relays mount directly to the bracket itself, guaranteeing the physical split between the two batteries while allowing you to connect them at will. While driving both are being charged and when turned off only the one is being drained while the second stands fully charge ready to fire the engine back up, very useful for cold temperatures. At the same time, with the push of a button, you can join the two together should you ever need an especially high power output, e.g. during long winching operations.  The monitor comes with an HBC systems is mounted directly to the dashboard for easy supervision and operation by the driver. This set includes all the necessary wiring, odds and ends, and hardware necessary to install it. The brands above ship their heavy-duty wiring harness with 35 mm² copper cables and mounts. The Cyrix system, on the other hand, is the value option and is engineered for lighter use. The Crix system can be upgraded with a monitor at any time, be aware though that the upgrade is far more expensive than just buying the HBC system (Cyrix incl.) from the start. Another upgrade to any of the models is to expand the system with a heavy-duty jump cable and a third party electricity source for long stays at campgrounds. To simplify the wiring mess and ease the potential search for faulty connections we recommend our fusebox with power and grounding distribution, to be mounted underneath the passenger seat. The Set comes with: 2x AGM Batteries (80 Ah Capacity)  Nakatanenga dual battery rack  Wiring harness from 35 mm² copper wires and with high quality hardware and monitors  EITHER Battery monitor with fully automated relays (HBC, IBS, National Luna) or only automated relays (CYRIX)  Hardware Illustrations may vary.
