     CHARGING OBLIGATION - Lithium Batteries must be charged using:

      For on the go, DC to DC charging we recommend either a 30A Batt to Batt charger or a 60A. Rate the charger based on your demands / loads from your aux battery.



     For caravan installation, due to limitation of cable thickness and long cable runs we highly recommend using Sterling's BBC Wildside Battery to Battery Charger - 25A unit.



     For AC to DC charging, from mains or generator, we recommend a Pro Charge Ultra 12V 50A or smaller

    Lithium batteries general overview:

    The advantages of lithium batteries are well known over conventional batteries. They are superior on every level - everyone wants them. However installing them on vehicles  was not simple and required a lot of knowledge because they have a very specific envelope for their charging and discharging curves. Failure to operate within these parameters will reduce the performance ability and life of the battery. It may even destroy the battery and even cause a fire. This fear has led to many people backing off from the whole idea of lithium batteries.
    For many years people have wanted a simple easy solution to installing lithium batteries in the automotive industry:  Including commercial vehicles, campervans, caravans, military, police and ambulances. However, due to the specific incompatibility with charging voltages and currents on board the vehicles and the requirements of the battery, the two things simply could not safely be brought together without a very elaborate intermediary system linked into a BMS for the lithium battery. All this is not gone; today we have lithium batteries with built in BMS and automatic shutdown systems that take care of the extreme faults that may be presented to a lithium battery. With the simple addition of a Battery to Battery charger the correct voltage and current profile is provided to the battery from the vehicle's alternator with no integration fuss. This means, when your alternator voltage is low, the battery to battery charger increases the voltage and when your alternator's voltage is too high the battery to battery charger decreases it. Also, when you have too much current, the battery to battery charger reduces the current, thus, presenting the lithium battery with its ideal safe voltage and current requirements. This has never been so important than with the modern Euro 5/6 vehicle applications. The first, all in one - simple to install - package that removes all fears with this technology for application on vehicles.
    Key installation points and advantages
    Performance: Because a 100Ah lithium battery allows total access to the full 100Ah as opposed to a normal lead acid 100Ah battery which realistically only allows access to 50% - about 50 Ah. Therefore, you get the equivalent of 2 x 100 Ah standard batteries to 1 lithium.
    Battery weight: Battery size to battery size lithium is about 1/2 the weight of a conventional lead acid battery. However because you get 2 x the power from the same battery in fact a lithium battery is about 1/4 the weight - power for power.
    Charge performance: a lithium battery can charge much faster and fuller. I.e. when a normal lead acid battery is reaching its capacity the power intake tapers off very quickly, not so much with lithium it can sustain the charge curve for much longer. It also holds its output voltage longer ensuring maximum performance for the products attached to the battery.
     Life expectancy /  economics:  A typical lithium battery will last between 10-20 time longer than a conventional battery making them very economical.
