Super B Epsilon 12V90Ah

[kelv]

Just wondering if any one has these batteries I have two fitted to a carthago motorhome and they seem to be discharging by about 10% a week when everything is turned off.
The app I have to check the power is saying -0.01a on both batteries.
The app also says I need to pair my device with the battery by pressing a button on the battery which I can not locate.

If it’s button S1 it’s location is showing in these instructions,

Re the discharge, do you have the batteries isolated? Or just the Hab electrics turned off?

Yes I think it is button s1 thanks for the instructions did not think I had to unscrew the cover after seeing instructions it has become clear.
Just hab electrics turned off

Are you putting the batteries to sleep? Mine are switched off at 80% and they lose nothing over many weeks.

If we turn off the panel we still loose 1A per hour so I isolate at the battery switch and then an amp or two go into the starter battery every now and again,

I'm having a similar issue with one of my KS Energy 120Ah. Spec says about 2.5% per month but whilst the second (newer) one remained at whatever % charge it had, the original ( now 18 months old) loses about 5% a week. Yesterday I ran both down to 'shut-off voltage' and have now almost recharged to 100%. The trouble is the App is showing all manner of spurious data. At one point the second battery was 211C but now reading 15C. The cycle count jumped from 2 top 8000 at some stage yesterday. Battery voltage reads around 48V with individual cells @ 28V. You can't believe a word the bluetooth tells you!! So, is the original battery really losing 5% per week? Who knows.

Batteries need to be isolated from solar panels. I pull the fuses on the solar controllers. On the app there is an orange half moon symbol top right. Tap that. And confirm. Batteries can be woken by receiving a charge. Either plug in EHU or replace solar fuses.

In case you don’t have it this is the link to the Super B Epsilon manual.

Look at Section 7 Storage. They call sleep mode the storage mode.

Hope that helps.
