Battery box with various connections, incl. TM500 charger and adapter Optionally with AGM or LiFePo battery You don’t have to go too far from home before you realize how dependent we’ve become on all our little electric helpers and gadgets. Whether it’s a camping trip, the construction site or an expedition, no juice, no play. And that means no laptop, no smartphone, no sat nav, no light, no fridge, no tools. With a multitude of mobile devices all depending on a power outlet, it’s crucial not to rely on your car’s starter battery alone to charge them all, because the battery could be flat in no time. And who wants to run a noisy generator around the clock? So you better call one of our high performance battery bundles your own. It’s the perfect solution for everything that needs running or charging in off-grid situations. The bundle comes with everything you need for operation and charging of mobile devices. Center piece is a 12V AGM battery with a capacity of 33 Ah or optionally 12V 35Ah LiFePo Battery. Solidly mounted inside a robust box, you can transport your power storage in comfort and style and use it flexibly and safely at your destination. Two USB and one standard on-board power socket (“cigarette lighter socket”) provide ample charging capacity (if necessary via power adapters) for mobile devices. You can charge the battery box either with an environmentally friendly Optimate solar panel or with the Optimate DC-to-DC charger. Simply plug the SAE-to-car/bike cable in to the on-board socket or cigarette lighter and charge the battery box efficiently and gently, preferably while you’re driving and the generator is supplying the electricity. LiFePo4 batteries – with their lithium iron phosphate cathode material – are perfect for running your camping or work utilities on the road, especially in conjunction with our mobile battery boxes. Unlike your conventional AGM lead-acid technology, the lithium battery combines vastly superior charging/discharging qualities with extremely low weight and small volume, respectively, and a long service life. LiFePo4 batteries tolerate deep discharging without problems, unlike AGM batteries which will suffer irreparable damage when repeatedly discharged beyond 50%. Unless you require the greater tolerance for extreme cold in AGM’s, you should definitely consider the higher initial costs of LiFePo4 batteries and compatible chargers. Enormous weight and space reductions, the long life-cycle and the hassle-free charging and discharging of the battery are strong arguments for the investment. And last but not least: LiFePo4-technology is extremely safe. Never run out of juice with our Nakatanenga battery box bundle – all on board, all the time. Bundle consists of:1 x Nakatanenga portable power station 1 x Optimate DC to DC charger 1 x Optimate adapter

Battery box with various connections, AGM or LiFePo battery In the 21st Century modern technology is everywhere, even off-road and off the grid, but more often than not there is no power when you're out and about on some trail in some country.One option is the classic cigarret-lighter as a power source, but in using this frequently you risk decharging your battery to a point where it won't start your car anymore. Another option would be a generator, but those are loud, impractical and noisy. To solve this probem highly portable powerbanks were invented, but for a multiple day long trip a small powerbank just won't cut it.So, what if you had a lagre but portable power bank? One you could simply charge, even off the grid, maybe with a solar panel? And one that is heavy dut enough to endure week long trips and years of use ? Hold on, that's exactly what we did!

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).
