1S lipo charger???

[Dougelove]

I have a X4 quad, (3.4v@380mah20C) however the "charger" requires a PC USB for power & well over an hour!!. This is not always possible. So I'm looking for an alternative wall charger to suit. Any advice? I have a Imax B4 but I believe this is 2S up.
I was thinking of an old phone charger adapted to incorporate a USB Female end to plug the "charger" into. I know USB is 5v. The Nokia charger I have is 4.5v @ 350mah, will this suffice? Has anybody got a 5v 380mah old plug? OR am I way off? Any advice appreciated. Many Thanks.

If you use any other charger then charging at 350mah will still take an hour+.

If you are just trying to avoid using the computer as a power supply then all you need is something like this:

The charger you plug into it will still supply the correct charging current.

Please don't go down the route of trying to bodge a phone charger to suit.

In RC we are lucky enough to have a wide range of chargers that monitor the cells properly and give you a safe, fast charge.

You can get a mains powered charger that will cope with pretty much any battery you can think of and give you a full readout of what is happening for under £50 from most UK shops.

Sparky thanks! I have 2or3 of those kicking around!! Didn't think I could use them as the OP is 2.5 & 5mah! So I can safely use this with the original usb charger then? Thanks.
Sosidge- Point noted & taken! I have a genuine imax b6 (yes it was hard to get!!) can I use this with a microT connector direct banana plug input?

I am aware that you can't rush charging Lipos unless you want fireworks!!

Therefore time is no issue (I now have 7 1s's thanks to a bargain misspelled find on eBay).

I merely want to eliminate firing up the PC or laptop every time.

Thanks guys I'll await your response. Cheers.

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.

Thanks all understood.
Next question. How do I connect/make a balance lead for multiple 1s?
Much appreciated
Cheers.
