    Has anyone charged an electric bike battery via an inverter when driving? If so what inverter. Looking at 36v battery so not possible to cut out the middle man unfortunately.

    Yes, have a cheap Aldi one (300w ?) more than enough. Note AandN are working on a dc-dc transformer which should be more efficient.

    I have a 600w pure sine wave inverter + a 3 110amp hr battery pack + solar panel. Plenty leccy to charge my Freego 16amp hr battery. I am off grid for 95% of my fultime moho'ing. 😊😊

    I have a 700 watt inverter, had our electric bikes for about 7 years they are the folding ones from AS bikes. Was told when we bought we would need a minimum of 600wattstocharge them. Did try the 300 watt one we had & it just didn't work, no problem though with the 700 watt. It is made by Silverline which offers free 3 year warranty, we got ours from Argos, found it was getting very hot & fan didn't seem to be working after about 3 months. Spoke to Silverline & they said to return it for replacement or try taking it back to Argos. Tried Argos & they replaced within a couple of days.

    Our 2000w inverter does the job, only charge while on the move.
    The value of a man should be seen in what he gives and not in what he is able to receive.

    That seems to be the best solution.

    My 150w modified sine does the job absolutely no problem. 2000w total overkill.

    I agree, however my 150W modified sine wave charger will only charge one battery at a time. We have two bikes, two chargers and the inverter can't quite power both at once.

    It might be worth looking at that 500W MSW inverter I got from Amazon for my "B2B style" charging experiment? Output genuinely over 400W and cost just 21. Apart from the rubbish croc clips on the cables, it seemed to be a pretty decent job, especially for that price.

    Thanks

    Ok it seems a 600 to 700 watt should do the job and I only intend to use it while driving. Thanks for confirming the basics, I will sort it from here.

    Thanks to all who took the time to respond.
