What does it mean when a blue light blinks

Blue Blinking Lights
The 2S Balancer has 2 blue LED's that may blink from time
to time. What do they mean?
If you look at a picture of
the 2S Balancer you will notice there are 3 small LED's on the board. One
at the top near the connection, and 2 on each side of the
balancer.
The LED at the top is a RED LED, if you see this illuminate
it means that you have connected the 2S backwards. At Fromeco we
always try to only use RED LED's as warnings. This is in fact what
this is. If you see RED it means you have connected the balancer
backwards. You need to unplug, and either flip the connection, or
inspect your wiring to make sure you don't have a systemic wiring issue
(backwards from the battery etc.)
The BLUE LED's. There are 2, one on each side
of the board. Each LED represents that LEDs' cell (each side
of the pack). If you see the Right side BLUE LED ON
STEADY--BLINK--ON STEADY--BLINK this means that the Right cell in the pack is
high enough to trigger the balancer to come online and balance that cell back to
its brother in the pack. The tolerance on our balancer is about 35
millivolts. So it takes very little for this to
happen. NOTE: This is not unusaul, this is normal. If you
see a blue light come on for a little while this is OKAY, this is why you bought
the 2S balancer it is doing its job.
How does it know? The 2S Balancer utilizes a
sleep function which has a wake up routine. Basically
the 2S Balancer spends most of its time asleep, waking up for a
millisecond to check voltages and then going back to sleep. When the
Balancer wakes up and sees an imbalance larger than 35millivolts it goes to
work.
