I’ll take the risk and install the update, I don’t have any other option. Since it’s a 2021 series, the components are faultless, so if the software can break them, it shouldn’t
sorry for the mistakes, I’m writing with a translator

Hello IP22 owners,
We have firmware version (3.68) with even more improvements to correct the pulsing behaviour.
This version is for the IP22 single-output chargers and for the IP22 12V triple-output chargers.
For the triple‑output IP22 chargers, the recommendation is to bridge the unused output(s) to the output connected to the largest battery.
Not bridging the unused outputs makes the voltage regulation less stable, and the output voltage will be 60 to 200 mV lower under low load (down to 0.0A). Without bridging, the charger is still safe and usable.
The 24V triple-output models did not have any issues, so no firmware update is required for those.
Hi ! for me it is worst then 3.67 02 BETA, Amps are droping about 0,5A on multimeter worst then in app. In app 1,2A in multimeter 0,7A ….

Take it to a store and don’t think that software can fix the faulty, low-quality components inside. Victron tried to save money and ended up in a mess.

I’m curious if the 2024 series could also be affected? Did the defective unit appear in 2025? To my surprise, a week ago I bought a Victron 12/20A HQ24, from 2024, but I don’t remember the week. As I mentioned, I installed the 3.65 update before using it. I didn’t have to do this because it wasn’t mandatory (just like with the HQ2021 version, where it is mandatory; otherwise, you can’t use the app). During the trickle charge phase, there was a clicking sound and the voltage fluctuated between 0.8A and 10A, and the unit was from 2024. Maybe it also depends on the week of 2024? Most people say the 2025 series is defective, but everyone with an HQ24 says it works fine after the update. I have a new battery, so could that be the reason the charger is acting up? The charger supposedly works because the HQ24 had one? Or maybe it’s just a faulty device? I’m writing this with a translator because I’m from Poland, so I apologize for any errors if any creep in 
Seems worse. On a practical level, LED lights in my camper are flickering when the charger starts absorption. I am switching it off now when charge state reaches around 80-90% on bulk. Concerned about possible damage to my Fogstar Drift 300
Serial number is HQ252246C3F
I have contacted the dealer to request an RMA when new stock is available. They didn’t seem to be aware of this issue, and initially suggested it would be fixed with new firmware, so I pointed them at this forum thread.
Out of curiosity, I’m asking if the new HQ26 series of Victron devices is already in production? Are there any stores around the world that have already received the first HQ26 units?

Edit. I have followed the support process and asked the supplier replace the unit. I have spent a load of money with Victron and am happy with the product so they should replace the BSC.
I recently purchased a BSC IP67 12/25 charger that is exhibiting similar symptoms. It is running the 3.65 firmware and the serial number begins with HQ2444.
In Storage mode with a 92 AH AGM battery and no load, the current spikes by up to 3 A every 15-20 seconds. The voltage jumps from 13.27 to 13.52, then declines and jumps up again along with the current. If I add a load of 1A, the output stabilizes. Here is a screenshot
I assume this is not normal. Is the 3.67 firmware likely to fix this problem, or is this a hardware problem?
I am observing the voltage and current with a SmartShunt.
Thanks for your help.
I have a brand new IP22 (single output). It upgraded its firmware to 3.65, when I plugged it in for the first time today. It is showing the same voltage and current spikes described by others, when in float mode on an AGM battery. The serial number is HQ2538. Is there a fix for this, please? Will it have damaged the battery?
No one will fix it for you, return it to the store where you bought it.
To fix the issue immediately, you can install firmware v3.68-beta-01 that @guystewart posted on Friday in this topic.
Here you find the manual firmware update procedure: IP22 manual, Chapter 6.4.2: Manual firmware update
Or you can wait until v3.68 is released in Victron Connect.
No worries, the pulsing behavior is not harmful for your battery. In rare cases it can interfere with the transition from bulk to absorption, but that is not the case with your setup.
Thank you. That’s helpful.
Given the uncertainties about this version of the IP22, I’ve decided to return it to the retailer and wait for a better version to be released. I have a 15A IP65 which will keep me going in the meantime.
Hi @serglob,
Standard handheld multimeters measure RMS and may not report an accurate value for the IP22’s modulated low-current output.
Hello, does anyone have software version 3.42? Could someone post a download link?
Hello everyone,
I have already posted in this thread about stability problems with my power supply.
Since then, I have installed the recommended firmware updates, but the device’s performance is still not acceptable. It continues to operate noticeably less stable than properly working units that do not have hardware-related issues.
Following your advice, I submitted an RMA ticket requesting a replacement of my defective unit with a properly working one. In the ticket I described the issue and mentioned that I had tested the newer firmware versions, but the result did not meet expectations.
However, instead of an RMA replacement (or at least confirmation that a replacement would be provided), my unit was sent back to me with a new 3.68-beta firmware installed. I tested this beta version as well, and the stability problem remains.
In power supply mode, I still observe current jumps/spikes of around 8 A.
Could you please explain why Victron is not providing the promised replacement in this situation? I paid a significant amount for the 12/30 (1), but I am effectively left with a defective product that is being “fixed” only to an “acceptable level” instead of being replaced with a fully functional unit.

Because there are no new devices available yet, Victron doesn’t have them on stock right now.
Hello, I have a similar situation. I bought a Victron IP22 20A charger, two with codes: one HQ2446 and the other HQ2448, so they should be fine. When I charge the battery, I set the current to, say, 10A and it charges to 1.3A. It goes down quite smoothly, fluctuating between 0.1 and 0.2A, so it’s fine. However, at 1.3A, after a while, the behavior shown in the video begins, and then the charger’s operating characteristics change. It makes a “slip and fall.” Both are the same. I returned them and bought a new IP22 15A charger with code HQ2438, so it should be fine, and the same thing happens. When the current drops to 1.3A, the behavior shown in the video begins: “jumping/walking current.” I checked it on two batteries: one a two-year-old AGM and the other a new AGM. Strangely enough, a friend of mine also bought the same 15A charger with the same code. HQ2438, except that it has letters, e.g. HQ2438ABC, and I have HQ24384ABC, the additional digit is 4, and it charges correctly on four batteries, meaning the current drops smoothly and there is no fluctuation greater than 0.1. It’s impossible for me to have three chargers, two 20A and one 15A, all with the HQ24 code, and the same on each of them… so it’s either the batteries’ fault… because it’s strange.
https://www.youtube.com/watch?v=uVhinJzmNIg It’s not a fluctuation like in the HQ25 series, where the current jumps, for example, from 1 to 10A alternately. Here, the jumps are of the order of max. 0.5A, but they exist. My friend has the same charger, four batteries, and there are no jumps on any of them, it just charges smoothly, while in my case the jumps on each one start at 1.3A.
Will the HQ26 versions for IP22 and IP65 be available in April? If so, is it early/mid/end of April?
