    I am following all the comments and useful information about using inverters. Yet another question!
    I would like to charge our electric bike batteries up, particularly on the continent. My extremely limited understanding of anything electrical is that I can and it is advisable? to charge the batteries up while on the move with a pure sine inverter (thinking of a 700watt) connected to the leisure battery. Keeping the lead as short as sensible and disconnecting the crocodile clips when not using the inverter?
    My silly question then is can I use a double adapter socket in the inverter to charge both batteries (each 90watt 2amp) at once? Instead of having to charge each one separately.

    Yes you can split the 230 volts into the two chargers, you will be taking around 10 amps off the 12 volt feed so if you try it off the leasure battery whilst it is not on a float charge it will not last that long. If you are charging whilst driving it may be better to connect the inverter to the vehicle battery, this is what I do.

    Trying to keep this simple.:Smile:

    What crocodile clips? You were not thinking of connecting a 700w inverter to the batteries using croc clips I hope! It should be hard-wired with clamp connectors and thick cable.

    er... Well yes I was just going to clip them on. Mainly because the inverter I looked at had them. Now I think I understand that I should have thicker wire and bolt the leads on. So to disconnect I would need a switch between the battery and the inverter as well as the on/off switch on the inverter. Oh! Dear I'm going to stay in my garret methinks I'm safer with a paint brush.

    Is it not possible to get specific 12v adaptors /chargers for your bike batteries, I think this would be far more efficient than using an inverter.

    Have a look at this article in the downloads section - it's one I wrote earlier to paraphrase a well known saying. It refers to installing a small inverter, but the principles are exactly the same. It may give you some ideas about how best to solve your problem.

    OK Understood

    Thank you all for your in-put. Jean Luc I read your practical guide and what a brilliant piece it is. What it did do was to convince me that what I thought a simple task is not. Well not for me anyway. Keep it simple is a very neat statement the problems develop when the simple bit is the doer. i.e. me!
    I'll go back to the garret and stick to something I can pretend I know how to do. If I do go down the inverter route I'll hire a professional.
