Battery blinking blue light

[levitan50]

It seems that cell is having issues balancing with the other two cells. Try using the USB cable mod to bring it up to the same voltage as the other two cells then place it in the charger again. It should finish balance charging within 30 minutes. If it fails to balance charge in that time check the individual cell voltages again and report them here.

This battery may be finished after that length of time with the cell at such a low

The cells are now as follows 4.04, 4.04, 4.05. Put it back on the breeze charger and got a solid green light when I put it in. Outside of flying my breeze with this battery, is there any way to run it down so I can cycle it thru again? I put this battery in my breeze and it seemed to work as I saw 100% battery with the green dots on my breeze app.

Agree with @DoomMeister : if that cell has had that voltage value so low, battery is unusable, sure not for fly.

I have wired them to an automotive lamp or two in parallel to drain them down. Use the two outside contacts. You can also use the Breeze. Just let it hover until you reach about 30% and land it. The level will rebound to between 11.1 and 11.4V which is storage voltage.

Got a break in the rain and wind today and took the breeze out with the reconditioned battery and I did hover it only until it showed 40% in the app and then landed it. The breeze hovered well which tells me I didn't have any major damage from my previous crash. Like all the others, I thank everyone for their support on getting my Blue Light Battery back to operational.

You are most welcome.

If you are not using the battery you should store it at near 11.4V, and check it at least every 30 days. If it gets down to 10.5V (3.5V/cell) charge it and then discharge it down to 11.4V for storage.

All three cells are @ 4.05 and 12.19 overall. is that too high for storage?

Yes.

You can use the Breeze to discharge them. Fly to 30% battery level and land. The batteries will rebound after cooling to about 11.4V (3.8V/cell). A final voltage of 11.1 to 11.4 will do fine for storage. As I stated in an earlier post, check the voltage at least once a month and if it drops to 10.5V give the pack a full charge and discharge back to storage level again.

This is what I have could be of some use?

I charged my reconditioned battery with the Breeze charger and all went well, even the balance charging. Thanks all, Another battery saved. I will follow your advise

I did this and it worked. Thanks!
Yes, THE PISTONS, I just stripped the wired and used alligator clips)

This is and end on view of the Breeze battery.

This is a USB cable I modified to supply +5VDC to pins that will fit in the connector on the Breeze battery connector.

This is a diagram of the battery pinout. Use a multimeter to measure the voltage of each cell. Use the modified USB cable with a USB power source to charge the cell with the lowest voltage for a minute or so.

Now place it on the Breeze battery charger to see if it will start charging. Repeat several times if necessary to get the battery pack to the point that the charger will charge the battery pack. If the battery pack will not charge after several attempts, and good batteries work with the charger, the pack is bad.

The Breeze charger is a balancing charger. The last few minutes of a charge cycle you will see the light flash green and red and finally solid green when fully charged.

EDIT: 24 May 2018

Lately there has been several posting with bad Breeze batteries where 1 or more cells have been run down below 1VDC or even to 0 volts. For a cell to run down that far, it has suffered major trauma for a LiPo battery. Chances of recovering a battery in that condition is very unlikely. It should be used with great caution and never left charging unattended.

The simple rig pictured above was intended for use on s LiPo cell that was just below what the stock Breeze charger would accept and charge.
A LiPo cell at 3.2 VDC is theoretically at 0% charge and 100% at 4.2 VDC. That is only a 1.0 VDC difference. I would only recommend using the above setup on cells at 3.2 VDC and above.

Thank you very much for making such an instruction
i managed to recover cell number 1 from 0.01V
God bless you!
thanks again good luck!

Sounds like you left it in the charger for an extended period after charging was complete.

Be cautious flying with that battery until you see how long it lasts.
