Link 10 Problem

I have set up my Link 10 to indicate that my battery bank is 420 Amps, but when the bank is fully charged, the indicator says that I have 255 hours left in it. I have triple checked that the Link 10 has 420 Amps as my battery bank but I still get the 255 hour number as hours left when charged.

Can anyone give me some guidance on this? Thanks in advance for your help.

Re: Link 10 Problem

I have the link 10 installed with a similar bank size. If you do not have the installation manual you can download it. There are 2 versions of this amp hour monitor but in either case the count down will max out at 255. I have not found this to be a problem, it is an indication of the hours left in your bank at full charge and your current rate of discharge. My documentation is on the boat covered in ice so I cant get any clearer. There will be a follower who will give you a more technical response. 225 is the max you will see.

Re: Link 10 Problem

I believe that's the maximum number it displays, 255, and goes down from there. That is the time you have left in hours at the present battery drain, not the size of your battery bank. It will show CCC when it senses bank is full SOC. You do need to set your bank size into Link 10 settings.

Re: Link 10 Problem

Thank you for your input.

I'm a bit challenged when it comes to these things, so let me just make sure I've got it. The Link 10 will show 255 hours even if there are more than 255 hours available at the current rate of discharge because that is the max number in the system. Do I then assume that it will start to show less than 255 only once we discharge to that level?

Also, in that I have 420 Amps house system and I want to charge at the 50% discharge level, do I use the "hours left" indicator to tell me when to fire up the engine and if so at what number?

Thank again for your help.

Let's keep this simple. Begin to charge when the battery voltage gets to 12.15V - 12.2V with your average house loads running.

Ah counters are very, very difficult to keep accurate for SOC even for the most skilled users. Easiest to just keep it simple and don't let bank voltage drop below 12.15V - 12.2V, unless you are running big DC loads.

Re: Link 10 Problem

Learning how to use your Link 10 is not all that hard. This is a LOT of reading but explains how they work. You NEED to learn this stuff. None of us were born electricians.

Re: Link 10 Problem

255 is the max hours the unit shows. and I belive will show that under charge as well


this is the number of hours left before the battery dies with what you are running at that exact moment.


it will go up and down as you turn loads on and off (avgered over a few mins)




do not confuse hours with amp hours. they are different. so is amps.


you battery is 420 amp hours. not amps.

the hours is just a covenance thing, and is probably not often used. if you pull 420amps from the battery (big inverter) it will last an hour.. and the meter will show an hour. even if full.

if you are drawing 4.2 amps (few lights on) it'll show 100 hours left. when the battery is full...

it should have a amp hour window no? when it's at -210, you're at 50%.

the display probably has has volts, amps, amp hour, time remaining. it's the amp hours you would be mainly using the gauge for.
