Re: [Amel Yacht Owners] Link10 Battery Monitor Issues

Bill & Judy Rouse <yahoogroups@...>


Yep, the darn Link 10 is a poor piece of equipment and the Link 10 manual should get the award for the "worst written technical document ever published." I cannot imagine how someone whose first language is not English could ever understand this manual. I read it, re-read it, and re-read it again...I never understood it!

I guess that you have a malfunction, but before I would replace it, I would look at the shunt on the negative side of the batteries...I would loosen the connections to it, brush some corrosionX on the terminals and tighten back up. If everything is not perfectly connected at the shunt, you will have weird readings.

If that does not work, at least you are in the land of a thousand choices and all of them deliverable in a day! ;)

Hi Bill,

We do not have solar. The wind generator is disconnected during trouble shooting. We have made no wring modifications.

Charged Voltage is set to 26.4

Charging Efficiency is set to 002

Peukert Exponent is 1.07 per battery manufacturer

I do not understand how it is possible for the unit to show a positive amp flow with nothing on. The positive will go to negative with loads greater than 10 amps.

With best regards,

Do you have any solar connected to the bank?

Have you connected anything to the shunt inside the battery compartment?

In perfect conditions the Link 10 is a little better than nothing. Unfortunately it does not record things correctly even when all of the settings are correct. The critical settings are:

Charged Voltage which must be at least 0.1 volts below the battery specs...maybe 0.15, or in the case of 24VDC, 0.15 X 2 = 0.3 volts.

Charging Efficiency Factor which should be set at probably set somewhere between 3 and 10. I have ours set at 3.

Peukert Exponent which I have set to 1.13 for freedom type lead acid batteries.

Reset of Amp Counter: Even when everything is set correctly, the Link 10 will require a reset from time to time. Procedure for reset:
Press SET until SEL appears in red, then press SEL five time until AH appears in red, then hold SET until ALL appears in red, then release right away...if you hold it too long, everything is reset...AND you will have to enter all of the above again.

When at anchor, I charge the batteries until there is between 25 and 29 amps going into the batteries.

We are having issues with our Link10 battery monitor.

We have reset and re-programmed the unit a number of times trying to fix this issue over the past few months. We are certain it is programmed correctly. The unit did work correctly and reset itself after charging up until about 6 months ago.

The unit is not measuring an accurate flow of amps going into or out of the battery bank. It is off by a factor of about 5 amps. Example: We are on a mooring buoy and the unit reads 5 A (positive) as our current load. We know we are using about 5-6 amps right now. The number should be negative. We have no chargers running. If we turn off everything DC with the large red battery handles, it will read 10 A indicating we are putting 10 amps into the battery. Because the unit is not correctly measuring the amp flow, it is not counting down or resetting when charged.

Has anyone else had issues with this that can give some pointers of things to check? Do these go bad?
