    Not much detail in there - I’d want to know max discharge current over time curves at least. CALB batteries aren’t bad though, so for the price should be fine. We haven’t used these particular units. In 12 volt we have some 300Ah Victron but we mostly run 48 volt rack mounted batteries but we have a some systems with 24 volt gear too.

    1 thing to watch out for is what your anticipated battery system voltage is going to be - if you’ll be running say 48 volts, putting 4 x 12 volt units in series isn’t the best way to go. Putting batteries in series can lead to depleting on of them or you could find one is not charging as well as it should due to slight differences in internal resistance. If you use a battery that’s at your rated output the internal BMS takes care of the cell balancing and this isn’t an issue. If your system voltage is going to be too high then it’s unavoidable but you’ll have to go to the extra effort and expense of using battery equalisation units between the batteries- these let a small amount of current around a battery when it’s full to finish charging others in the system that may not quite be full.

    Not a deal breaker but something to think about.

    grrr- I want it before Landrover suggest 2024

    Disco is booked in for a yearly service - I have a love hate relationship with it now. I need it yet hate the costs as it is not my daily drive now. The hydrogen fuel cell is likely to be the first option for really long range EV I suspect even it it is in the boot of a BEV


    Volvo is hmmm We need another way in towing and traveling and current gen EV is not up to many of our needs

    City 420kmCity driving and low average speeds tend to be the most efficient scenarios for electric cars. However, in colder weather, when you are more likely to use the heater and with other factors taken into consideration, the vehicle range is approximately 210km.


    Combined 360kmThis is a combination of city and highway driving. At an average speed that reflects these circumstances but in lower temperatures and with increased use of the vehicle’s heating system, the vehicle range is approximately 200km.


    Highway 300kmOn the highway at average speeds of around 100km/h, the power required to overcome higher wind resistance puts extra demands on the battery. In colder weather and in less than ideal road conditions, the vehicle range is approximately 220km.

    Are we there yet?
    was a question kids might state repeatedly. It is screaming out loud yet happily in some shipping sectors some carbon free helpful options are in play.

    So you have to buy an electric car within a few years but you’re advised not to charge it at high demand times. Anyone else see an issue here?

    Nah,only you and i that have been talking about this for what seems ages.

    Just imagine how that will go with work vehicles

    Other countries are load shedding EV charging stations at times,as well

    1. Cool conversion, but for a 53kwh battery the range of 150km seems a bit low. The range of the Leaf +, with 59 kWh is 385km.

    2. Interesting how many articles in that motor-trade magazine are about hybrid or electric vehicles.
