I think sosidge's concern is because your original post did sound a bit like you were going to try and charge the lipo direct from the power source.

So if you have a proper charger that plugs into a pc USB port then it will be fine running off a usb plug socket.

If you have a proper rc charger that runs off 12v they don't specify that they will only work to a maximum of a 400w power supply or a 500w power supply.

This is all you are doing, providing a power supply for your charger.


To bring in another option, if your b6 does 2s then make up a charging cable that links up two of your batteries and balance charge them on the b6 and you can charge 2 at once as long as you can lower the charge current enough.
