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. Please note the legal information on batteries HERE. For certain types of batteries, we are legally obliged to charge a deposit.  

MPP Solar-Regler  Please note that the solar charge controller can only be used with solar panels up to the maximum power rating (Wp) and below the maximum allowable voltage (Voc) may be used. The controller is not intended for an input-side connection (+/- solar panels) of wind, water, fuel or motor generators, power supplies, batteries or other power sources. The MPP solar controller for high-quality motorhomes, caravans and boats. Votronic solar controllers of the "MPP" series (Maximum Power Point) with “IU1oU2” charging characteristics are connected as a link between the solar panel (s) and the battery (s). With MPP technology, the controller automatically determines the maximum power output (MPP) several times per second the solar modules. The excess voltage of the solar module is transformed to a higher charging current for the battery, (realized by high-frequency switching regulator technology with high efficiency). The gain in charging current is used for shorter Charging times taken care of and for the best possible use of the solar system. The MPP solar controllers work fully automatically, are maintenance-free and offer the following functions: MPP charging current increase compared to conventional controllers through the use of the latest controller technology (microprocessor) by 10% to 30% (efficiency> 95%). The performance plus is particularly evident in the cooler seasons and z. B. in high fog, lower and diffuse lighting (overwintering). For charging lead-gel, lead-AGM, lead-acid batteries or LiFePO4 complete batteries (with integrated BMS, Balancing, safety circuit and approval!) Of the specified nominal voltages and the additional supply of an Consumers connected to these batteries in permanently installed systems with the specified battery capacities and charging programs. The charging voltage is free of peaks and regulated in such a way that overcharging of the batteries is impossible. Two battery charging outputs: Automatic charging of the main supply board battery (BORD I) as well as support charging and charge retention (max. 1 A) of the vehicle starter battery (Start II) with protection against overcharging. Monitoring-free charging: standard protection against overload, overheating, polarity reversal and battery back-discharge (with insufficient solar power z. B. twilight, at night etc.). Parallel / buffer operation: compliance with the charging regulations even when consumers are operating at the same time. Overcharge protection: regulates the charging current of the battery when there is too much solar power and the battery is full, ensures Power consumption through immediate recharging for the highest possible battery charge. "IU1oU2" charging characteristic: Defined charging voltage increase (U1) prevents harmful acid layers (lead) and ensures equalization charging of the individual battery cells (lead and lith.), then automatic maintenance charging (U2). Charging cable compensation: voltage losses on the charging cables are automatically compensated. On-board network filter: problem-free parallel operation with wind and motor generators, network chargers, alternators, etc. Measurement output for EBL, possibly existing electroblock in the living area of ​​the vehicle: Enables the convenient use of a (Solar) power display built into the electroblock to control the solar system. Please check in advance the compatibility of your Schaudt electroblock (EBL) and the corresponding control and scoreboard, as we cannot guarantee this. Switching output "AES" (only MPP 250, MPP 350 and MPP 430): causes permanent abundant solar The automatic switching of refrigerators with "AES" (Automatic Energy Selector, Electrolux / Dometic) from gas to 12 V operation. Connection for battery temperature sensor (item no. 2001): With lead batteries, the adjustment takes place automatically the charging voltage to the battery temperature, causes a better full charge of the weaker battery in the cold, In summer temperatures, unnecessary battery gassing and stress is avoided. LiFePO4 batteries: battery protection at high and especially at low temperatures. If the battery temperature can drop below 0 ° C during operation. Ready to plug in for the connection of the Votronic solar display devices LCD-Solar Computer S for optimal control of the system.
