Default bringing up a low voltage cell????

Hi all,

One of my turnigys right out of the box had a low cell. My turnigy charger times out when trying to balance charge. I put the cell on a friends charger that displays the voltage of each cell and it was pretty far off. I have had it connected to a blinky overnight, but it is still not balanced.

Is there a way (possibly using the blinky? I don't have it's instructions) to bring up that cells voltage more efficiently?

Does someone with a blinky want to share? I believe the instructions talk about it, but I don't have them.

Thanks!

would it work to drain it and keep balance charging it, or would it go poof?

Not a suggestion, just a ?.

Or call HobbyKing or wherever you got it and see what they can do for you.

Hobby king will replace it, but by the time I pay shipping both ways I might as well just keep it. It does seem to work fine. I'm sure it wont have the life of the others

One way to help get the voltage back up is to charge it at a very low voltage. Say something like .1 or .2 max .5 volts. As low as your charger will let you. Get it up to a more reasonable voltage then increase the voltage up to 1.5 or so. Let it charge, then cycle it a few time using a 1C charge rating and you should get the pack cells more equal. I have done this to Lipo's that I have discharged to much and the voltage has dropped bellow the critical voltage on one or more cells in the pack. If that doesn't work then I would send it back, even if it costs almost as much as a new pack. Because at least you will have a new pack and not worry about it's long term performance.

Bump the battery in nimh mode at low amps.
(Make sure you attend the full procedure)

Till the charger can recognize the battery and charge in Lip Mode with balancer on.

Thats how we been bringing some low Lipos to life.
Works on X-Charger/Turnigy Charger, Best on Hyperion and Triton EQ Chargers.

Blinky instructions here, near bottom of pg, look for "For more information, see the products PDF File". Click the "PDF File". I don't think this is going to hel though.

What you can try is setting your turnigy charger's time out to a higher time out for starters and let it continue to try and balance. The best way is to charge the cells individually - when I read that HC uses this device to save lipos I bought one - its paid for itself with the cheap lipos I get in trades that would normally get tossed that I've saved.

Another thing to try is a low amp charge, charging at low amps helps the cells balance themselves, might give that a try as well. I've seen this prob more than once and you can get them to balance unless that cell is just bad. It takes some time and when it does balance, it will tend to stay in balance with the others, you've just got to get it past this point where its at now.
