hi guys
how can we charge zippy flightmax 138 mah 1s lipo
and how do we connect it to motors?
from where can we get such a adapter that converts it plug to two bare wire??
please help me out
i have got 6 of them but don't know how to use

Without pictures of what is being talked about (or correct brand/model details), it is hard to say anything (especially on the connector part) :)

What motor are we talking about ?

the same one exactly brand new one
[i bought it from there only]

You should have got one of these :)  Then you could cut out a few and do whatever you want with them (use them for charging or to drive the motors).

There are more complicated ones : http://www.rcdude.com/servlet/the-1612/Hyperion-6-Port-Parallel/Detail

I could not confirm it, but the battery connectors used in JR transmitters etc looks very similar.

ok will try using the wire mentioned in the second link for that purpose
but then how will we charge it[btw i had started making 1s lipo charger circuit which was discussed in the topic[charging single cell lipos]
but i have a question-if we use that circuit + a 12vdc adaptop + a female to bare wire connector made from second link then how much time actually will it take and will it automatically stop charging??

Q2)if use the 1st link product then how can we charge  it???

and i m reffering to gws edp-20 motor at particular bbut actuaaly in a sense all dc direct drive motors

I am not sure about the specifics on the charger, I think someone like Rajesh will pitch in.  If these are single cell chargers, and you got the product in link 1 above, then you will have to cut out of the connectors, and use that to connect one lipo to the charger and charge them one at a time.

Basically, those two links were just suggestions for appropriate connectors that can "latch on" to the terminal of those lipos. Using them (either cutting them out, or directly with trickle charging) is up to you.

But I did notice that these motors typically work with 6 to 8 volts, so you would have to use two of them in series, right ?

ya,but some dc motors i have[orignal philips vcd motors] which run at 3.5v so they will be run directly

I was referring to the specs of the GWS EDP-20s. 

BTW, did you finish building the single cell charger ?

my 'ya' was for that only[gws edp 20 mtors will require them in 2s]

and i have not yet finished making the charger
first i m waiting for amir bhaiya to get the connectors for me

With a slight modification to Nokia Mobile Charger with female Micro JST Plug you can charge single cell Lipos of the brand you are asking. charging current is however higher, life of battery will reduce if it is lesser than 100mah. Further it will not switch off when cell voltage reaches 4.2V. which you will have to monitor manually and switch of before it crosses 4.22V. However further modifying using IC 7805, Zener diode, and micro pot you can ensure it reaches 4.2 V and stays there.

well i prefer to use the charger mentioned in the link
 charging single cell lipo (http://www.rcindia.org/batteries-and-chargers/charging-single-cell-lipo/)
i will use a 12vdc adaptor and will charge using it
 i will get this connector (http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=9727) [cut from middle to connect it]

just a question - will it stop charging automatically?

another idea-can we cut and use connectors to make a 2s lipo then charge using a normal 2-3s lipo charger??

please answer my q's asked till here to help me out

If you connect them in series and build a balance tap from between the various individual cells, you can use a regular 2s/3s charger.  You will have to locate a balance charge connector (can be pulled out from old lipos that have gone bad).

thanks will try that out!!

here are the pics of the lipos
