Battery Balancers behaviour. Should there be an alarm?

Hi

I have a question concerning the behavior of three battery balancers I have connected to my batteries like in the enclosed picture.

I have seen that the green light turns on on all the balancers , then with a deviation of more than 50 mV the orange led of the balancer in the middle turns on while the others are off.

I also noticed that with a deviation of more than 500 mV there is no alarm on the balancers. Is this behavior normal or maybe there is something wrong with the balancers or connections?

Regards.

@Giampaolo

There is a also a voltage trigger level. So it will only balance once your batteries have hit that level. Is the 500mv happening out of the trigger range? Check the datasheet.

Also a little demo page to show you how it works.

Now the balancer seems to be working properly. With a deviation of more than 500 mV there is an alarm and it also starts balancing the batteries after a deviation of 200 mv. Probably now I understand that only the balancer in the middle works because the imbalance is between the second and third battery in the bench.
