3cell tx lipo - cream crackered ??
 

Left my 3cell lipo plugged in my Tx over the winter and its discharged. Couldn't get any charge at 3S (under voltage limit) so hit it for 5 minutes at 2S and these are now up, however the 3S is still way down and not enough to charge at 3S rate :(

Is it officially knackered or can it be charged a 1S to bring the low one back up aswell ??

You could try using a nihm charger aat 1amp for 60 seconds at a time to slowly bring up the voltage untill your lipo can take over. A few people have had success with this.

You can try to bring it back from the dead but could you ever rely on it 100%, 100% of the time. I know the 'official' line when charging Li-po's is to never leave them alone when they are being charged - but i suspect most of us do ! Could you trust it ? ? ?

Best thing to do is buy a new pack, learn from the mistake, move on.

Yeah ordered some new packs but wanted to resurrect this one if i could.

Sounds like its chuck it time then :(

As above. I've been eyeing the LiFe tx batteries at Demon Power Products, very reasonable at £10. LiFe can still be over-discharged, but it's a more robust chemistry.
