    While zooming around the first link I found this pic, would this guy be using his generator and mains at the same time?

    If he has 2 onboard chargers theres no reason he cant use both at once. If the BP charger is a Rapid charger it will be charging DC direct into the battery , whilst the Generator is feeding the onboard charger.

    Depending on what C rating his cells are . My LifePo4 200Ah Prismatic cells are 2C charge (can accept 400 Amps) and 3C discharge ( can feed 600Amp into motor)

    My 3.3kw onboard charger plugs into a 240V 15Amp AC outlet & charges the battery pack at 168V DC / 22Amp , so no problems pumping more in at the same . Most DIY EV's have a 3.3kw 15A or 6.6kw 32A (3 phase) charger.

    Another interesting factoid is that having a bigger electric motor doesn't necessarily reduce your range. Running a bigger motor at the same output as a smaller motor means that losses in the iron core are much reduced. Reports are coming in that a dual motor Tesla M3 goes about 5 miles further per charge than the single motor model with the same battery. This is despite the extra frictional losses due to the second motor and drive components.

    I have an electric mower, an electric chainsaw and a shelf of electric power tools. They are great. Meanwhile the petrol ride on mower is dead and not worth fixing and the petrol Honda push mower died and is in the repair shop. I think I see a trend...
    Next step is to buy larger batteries.
    I think people still see EVs as toys and haven't accepted that they are the future here now.
    In 20 years electric vehicles will be normal and fossil fuelled vehicles will be regarded as quaint classics, like early Holdens are now, I predict.
