Default Blinky Balancer ???

I use a AstroFlight Blinky Balancer.

I have a question on the status of the LEDs. I checked the manual but the symptom i am seeing is NOT in the manual.

Problem:
I have an ORION 7.4v 2S-1P 3800mAh 30C bettery and when i install the Blinky to balance it. The Cell 1 led constantly blinks every 1 sec.

I also have a Flightmax 7.4v 2S-1p 4000mAh 25C Battery and it aslo does the same thing. Both of these batteries have the same type of connetion where they are removable and the balance port is in the middle.

I also have a IP 7.4v 2S-1p 4000 20C Battery. That the output leads and the balance port are NOT removable and this battery balances the way it should. I starts with the LEDs on and when it is done balancing they all turn off.

Here is a pic showing the batteries.


any ideas? Is this normal?

That sounds normal to me. The first thing to check is that both lights come on after you plug the blinky in. This means that the cells have enough power to be charged rapidly. Then the next thing it does is discharge the cell that is higher in voltage. In your case it's cell one. It will discharge at .025 amps until the cells are equal. If you have one cell that is being discharged all the time, it just means that cell 1 has more voltage than 2. It may take awhile but it should all work out. Also you can always check your voltages with a multimeter to see just how far your cells are out of balance. Since you are having problems with both battery's that use the balancer harness, I would also inspect that very carefully, check soldier joints and resistance, if there is any. http://www.astroflight.com/pdfs/106.pdf
