Lithium Batteries Max Charge?

[Escapeesinmo]

Any idea why my batteries never charge above say 78%. The coach was plugged in to shore power overnight with the fridge running. I took this picture this morning. I have an E23 with the zap pack.

Not familiar with Escapes Zap pack setup but I do have Victron equipment. Your display shows 14.2V which is 100%. I suspect you need to synchronize your shunt to 100%. There may be other explanations I'm not aware of. It's also possible the charging profile may not be set to Lithium. I'm assuming you have lithium batteries.

Yes, I have the standard Victron and Hublion (batteries) set up that comes with the E23.

I think @SRS is correct - your batteries are fully charged and are thus not accepting further charge so you'll need to look up how to set your %-guage to 100.

Makes sense to me. Time to use my google skills and learn some Victron knowledge.

Your inverter/charger says it is in Float. The voltage is 14.2 volts which is above Float voltage. I think your settings for the charge profile of the inverter/charger (do you have a Multiplus 3000?) and for the Solar Charge Controller (do you have an MPPT SCC?) are not correct and are not coordinated. In regard to the battery SOC being 76%, I expect that the settings are again not correctly set for the shunt or the Multiplus. Either take the plunge into how to access and verify/edit settings in the Multiplus using either VRM or an MK3 dongle or find a Victron Technician.

Escape should be able to help. They might be able to connect to your system and check the settings remotely, or they can just walk through it on the phone with you. Something doesn't look right to me.

Maybe start with reading the Multiplus and MPPT SCC manuals and the applicable parts of the Cerbo GX manual. It would be a lot easier to just find a Victron person. They can quickly sort it out.

Yep, I'll definitely take a deep dive into the victron systems. Right now I'm knee deep in trying to polish this large beast. Here is a pic of the Victron stuff.

So I messed with The victron app. I went into the shunt and was able to set it to 100%. Now back to polishing the trailer.

The system will reset to 100% automatically when the settings are correct. The cells will be balanced, and the SOC will be 100%.

I think your voltage should currently be at or near the float voltage which should be set at around 13.6 volts. Check with battery manufacturer for the proper float and absorption voltage settings. If everything is set up correctly, the system will not require much if any attention and the solar controllers and the inverter charger will stay coordinated.
