You may need to go to the advanced setting s and set the voltages for you specific battery.

Go to the gear in the top right of the screen in victron connect

Check on your battery for the correct charge and float voltages then activate the advanced setting. Use them to customize your charging.

You can then activate user defined and expert mode and make it do exactly what you want

Hello Alexandra

The charger has exactly the same voltage set as on the screenshots you post. I also tried several times to return to the factory settings and work in User definied mode ... each time the result is the same, regardless of the different batteries connected. The Bulk cycle lasts 3 seconds for 14.4V (normal) and 3 minutes for 14.7V (high). The ABS cycle is always 30 minutes and RECOND 60 minutes. It looks like a problem after updating the firmware (I got a hint from another user). Now I am wondering if I can force reinstall the firmware or downgrade it? I was thinking about installing an older version of the VC v1.20 application, which has the firmware for my charger version 3.12 (currently I have 3.21).

Thank you for the hint and best regards.

If the charger jumps to the absorption voltage in a few seconds the is in most cases a bad or no connection to the battery.
Do you have a multi-meter to measure the voltage at the connections of the charger without a battery connected?

If there is no voltage the charger is defective and you should contact your dealer.

Is there a solution yet?

I am interested to find this post as this is exactly what I am finding is happening with my charger (IP65 12/30).
It keeps stepping to Absorption mode way before the preset voltage.
I would love to know why this might be happening.

My charger is powered when needed from a generator with more than enough output to supply the charger- it hardly loads it even in the short time it outputs the full 30A. I am charging LiFePO4 batteries.

Mich würde auch interessieren, ob es eine Lösung gibt. Verschiedene Blue Smart IP65 Charger 12/10 und 12/15 schalten bei halbvollen Batterien (AGM und LifePo4, 100 und 200Ah) bereits weit unter Volladung (zwischen 12 und 13V) in den abs oder storage Modus. Bei verschiedenen Lademodi. Ein 12/5 Ladegerät funktioniert.

Es sieht stark nach einem Firmware-Problem aus. Leider gibt es keine Antwort vom Support, weder Händler noch Victron. Die Geräte sind leider nicht zu gebrauchen.

I have the same problem with a BlueSmart IP22 24/16. The charger goes to early from Bulk to Absorb. At this time, the battery has only 27V. In the settings the absorb voltage for LifePo4 is 28,4V. A BlueSmart IP22 24/8 with the same settings works with no problems with the same battery.

I have the same problem as described above. I am frustrated to see this that is a common problem going on for nearly three years!

For context, I've tried 3 different new LiFePo4 12v 100 AH batteries from 3 different manufactures. I am charging the batteries and doing discharge and capacity tests before putting them to use.

I've tried various states of charge, including after a full capacity test. I have only the charger connected to the battery using Victron battery charging cables using screw terminals (I've tried three of them). I've verified the current shown in the VictronConnect app with a clamp on meter, hall effect style shunt and in one case, a battery's bluetooth app. In all cases my Blue Smart IP65 12|15 won't charge faster than about an amp. Also, in all cases, my Blue Smart 12|5 and my cheap Chinese 12v 20amp charger work as expected, charging at 5 and 20 amps respectively, with zero issues on the same batteries.

Also, since I can use the same battery charging cable with the 12|15 and 12|5 chargers, I know it isn't a battery connection issue.

I've had the 12|15 for two or three years. It's been attached 24/7 to two 100 AH LiFePo4 batteries which I use to power my CPAP. Since the current draw on my CPAP is low, I have no way of knowing when the problem started. I know that when I first got the 12|15, it bulk charged my batteries at 15 amps. I suspect that I at some point, I updated the charger's firmware (now 3.21) to the version that as others have reported has this issue.

You've posted in a few threads. Assuming that you've checked the steps outlined above, please get your dealer to resolve things under warranty.

Hello all

Same issue here. We were looking for issues with the battery in the first place, after the symptom of "no more charging via shore power". Until now we have tested five different batteries with different charging stats as well as types (AGM, LiFePO): Victron charger directly jumps to Absorption charging and charges way below Abs-voltage with less than 1 A.

The real suspicious part of that is that three same charger types (Victron BlueSmart 12/15), built in three different cars with different batteries (types, sizes), showed the same behaviour within a short timespan (about 2-3 weeks)!

@Victron: It would be great to get some feedback from your side!
