Got my first HK,Turnigy Lipos. Doesn't look good....

Sorry for your loss, I've ordered dozens of packs and never had a problem. Don't let it discourage you, it was a fluke.

Hope you dont commit fraud on the customs ???

Charge it as a nimh or nicd, and wait about 5 minutes, just sit there, read a book for 5 minutes or something.

After 5 minutes, try it again as a lipo.
Or try it as a liion, since the chemistry is near same, but liions are simply a .1volt lower, IIRC.

Same exact threads on multiple forums for something that can be easily resolved...

ive done it, its easy and not scary at all. i just have a duratrax charger it tells you where the voltage is at in nimh mode, just did it until it was over 9 volts. never had a problem since

freeze, since yours are 2s lipos, you want to stop charging once they get above 6v. 9v will likely cause a fire

what amp should I charge it at? My LHS said 1 amp should be fine. I"m so freaking scared of doing this in my apt thought....

[rawfuls]

1amp is fine, though I'd do it at .5amps if you're really worried...

[DCastaneda]

you really should invest in a lipo sack or at least use an old pot if youre that worried. Violent lipo fires don't really occur unless you overcharge and puncture them. So keep a watchful eye and once the voltage is above 6v throw it into balance charge lipo mode.

Just tried charging at 1 amp for 5 mins on Nimh up to 4v. Nothing, it still sees low voltage when it does battery check for lipo balance charge for 2S . I can only charge it as a Lipo if I set it as 1S and non balance charge mode.

the minimum voltage for a lipo pack is ~2.75v/cell anything less the charger wont pick up. most probably wont take anything less than 3.0. You seriously don't have a multimeter?

Yeah, I have an expensive one out in my company rig I forgot about. HOw would I go about testing the lipo?

[DCastaneda]

Just as Suicideneil said on BYT, just check the individual cell voltages. Set the Multimeter to 10 Volts DC and place the negative probe on the black balance plug contact and the positive probe on the yellow to check cell 1 then move each probe over one to check cell 2. Whichever one reads zero or very little voltage you need to charge. I would recommend hooking up the charge only to the bad cell in nimh mode to revive it.

Ok, just checked with my companies expensive multimeter. Black and yellow wires on balancing plug show 1.96 v and black and red shows 4.12v after about 5 mins of charging at 1amp on Nimh mode. The voltages keep dropping as time passes.

Freeze,
I went to solder on some of that 8 guage wire and it was a bear. I killed a deans connector before giving up. A 60W iron wont do the trick.
You should dissassemble the pack and find out which cell is bad and remove it. Then resolder the 8 guage wire back on to the single cell. If you put the 2S and 1S with a series connector you will have 3S.

freeze if you have a spare female JST connector or hpi micro plug you can fit the pins into the balance plug. (at least IIRC the spacing is the same). You need to make an adapter for your charger so you can charge only Cell 1 (black/yellow)
