  2. Re: Can I use any smart charger for Lithium batteries?

    I would guess that your old battery has a fairly high internal resistance and this causes the 2A pulse to reach a high voltage on that particular battery. Not a good battery to use for this test. My...

    Thanks for feedback.
    Did not know about that bit. Does it charge the 10,5V battery right up to 16,7V??

    You can, but it is not ideal.
    It would be better to have the feed directly from the vehicle's starter battery/alternator.

    Cheaper is relative.

    To charge at 8A you will need a panel of around 150W, and that will cost quite a bit more than the Midas charger at R1200.
