IP22 charger going straight to Absorption

I have a Victron BSC IP22 12/30 charger and a 120AH Lithium battery When I connect to 240v power, the charger immediately shows a voltage of 14.2v goes straight to Absorption, irrespective of the actual voltage. The charger is set to the Li-ion profile. Below are screenshots from both the IP22 and Smartshunt.

Can anybody suggest how I can get it to Bulk charge before going to Absorption?

Low Temperature Cutoff not working


I have a Smart Shunt with latest firmware with a ve.smart networking setup to 2 MPPT 100/50 and 4 Ip22 12/30 chargers.

Everything is using the Lifepo4 profile with a low temp cutoff of 5 degrees C

It simply doesnt work with the charging continuing at 4 degrees C

Everythings firmware is up to date and the synchronised charging works perfectly but alas not so the low temperature cut off

Any ideas as to why?

Blue smart charger Functionality Device/App

A few questions about the Blue Smart Charger IP22 Rev2:

-How does the triple output work, eg have a trailer with main battery bank and then have a secondary battery used with a trolling motor. So the trolling motor needs to be charged independently from the trailer batteries. All batteries are LiFePo4. Will each charge at its own rate and once one gets to the charged parameters stop on its own?

-Are there multiple profiles in the app for each of the 3 lines one the triple output charger?

-Can you enable/disable charging from the app? Can this be done for each of the triple output independently?

Blue Smart Charger - Supply mode using Smartshunt or bmv-712 capacity values

I am wondering if the Blue smart charger can use the reading from the smartshunt or bmv-712 and at a certain battery percentage cut off charging and go into supply mode?

Use case is in a trailer with lithium batteries and the desire is to not maintain the batteries at 100% but instead 90%, while still being able to leave the charge plugged in which could run an electric fridge or other low draw items.

Ideally I'd want to be able to have the Blue smart start charging again under a specific condition, say voltage level or charge level but that is not totally necessary.

Victron Blue Smart IP22 Charger 12V 30A Battery Connection Terminal Size


I am deciding to purchase

Victron Blue Smart IP22 SLA/LiFePO4 Charger 12V 30A

The battery connection terminal is listed a being for 16mm2 or AWG6 in the manual.

Could the manufacturer or someone that is capable of precise measurement please advise what is the actual size of this hole.

What is the precise size of the battery input terminal ?

Mathematically it has to be bigger than 4.52mm D

To accommodate 16mm it is probably at least 5.5mm D (cabac cable lugs have a 5.5mm hole to insert a 16mm cable for example)


Can it fit a 6mm D copper stalk ?


Can it fit a 7.7mm D ferrule ?


Yes I am trying to use 25mm cable for 'reasons' being that is the cable I have got already.

No I don't want a stud with a 25to16 tie tail.- Looks rough to me and I'm not keen on extra connections joints and hardware just because Victron didn't think to put a 6,8, or 10 mm terminal stud on this item.

Any help much obliged.

IP22 Charging 2 battery banks

Hello all. I just received my IP 22 30A/3 output charger. I intend to use it to charge a 12V starter battery and the house bank (2 12V batteries wired in parallel).

Is the IP22 smart enough to charge each bank correctly even if they are at different states of charge?

What is the recommended way to wire the charger to the house bank (2 12V batteries in parallel)? Should I run a wire, from the charger to each positive pole or is it ok to run a wire from the charger to one of the positive poles?

All batteries are flooded cell lead acid

Thanks in advance

IP22 charger absorption voltage way too high when joining a VE.smart network?

Hello all,

I have a IP22 to charge a bank of Battle Born Lithium batteries. On its own it works great. But when I join it an existing VE.smart network with a MPPT 100/30 and MPPT 100/50 solar charger, plus a BMV-712 battery monitor, it all goes wrong. As soon as I join the network the absorption voltage goes from 14.4V (which is correct) to 16.32V. Oops. That is not good. When I leave the network, all is well again. This test was done with the two MPPT chargers not doing anything (no sun on the solar panels). Anyone have any idea?

Thanks for all your insights!

Here's the weird Absorption voltage of 16.32V


Joined this VE.Smart network


Here's when not in the network, all is fine

IP22 rev2, MPPT, syncronized charging: how the storage phase is handled?

The second hardware revision of the IP22 is now supporting VE.Smart networking. It looks like Victron fixed the "too small microcontroller" issue in that revision. That is pretty cool!


There is a guy here that reports it is working for him.


When I look at the release note, see "Blue Smart Charger" section of the v5.42 release, I have few questions about synchronized charging of an IP22 and a Smart Solar MPPT unit. It is said the IP22 will become the charge master in a VE.Smart network. That makes sense. However, even if the charging profiles are configured identically on both IP22 and MPPT, only IP22 supports a storage phase in its charging cycle.

So, what happens to the MPPT when the IP22 switches to storage phase of its charge cycle at the end of a long sunny day? Similar use case, what happens to the MPPT if the IP22 is already in storage phase when at the beginning of day? Does it mean it require the storage voltage of the IP22 must be set the the same value of float voltage? What happens if it is not the case (storage voltage lower than float voltage)? Is there any plan to add support to a storage phase in the charging profile of MPPT?

Ip 22 Blue smart charger charging low amps

I am charging a 300ah Lithium battery using my ip22 charger using the lithium settings.

The problem is the charger starts putting 30 amps into battery ,before it has 200Ah in the battery the charging cuts back to 15-16 amps ,I would have thought it would keep 30 amps going in until the battery was at least 80% charged.

Blue Smart IP22 repeated 30amp then 0amps?

My IP22 Blue Smart charger is not working properly. It charges in bulk mode at 30amps for around 30secs, then the amps drop to 0 and it switches to absorption for around 30secs. This cycle keeps repeating.

I have tried using a replacement charger and the same thing happened. It has been working fine for around a month but has only recently started doing this.

Any ideas? Thanks

IP22 - Lead from charger to battery


I was recently gifted a VICTRON Blue Smart Battery Charger 12V 30A IP22 (3) Outputs to replace an old Euro style charger for my caravan.

Unfortunately, the gift did not include a lead to connect from the Charger screw terminal (AwG6) to my battery. I would prefer a lead without clamps.

All I can seem to find is IP65 accessories.

What lead do I need to go from the IP22 to the battery?

Which IP22 charger to buy (10A/20A/30A) for two battery sizes?


I plan to buy a Blue Smart IP22 charger for my two cars, but wonder which one is most suitable:

Car 1 has a 95Ah AGM lead acid battery

Varta recommends to charge these with I=0,25C to 0,35C, so between 24A and 33A

Car 2 has a 70Ah flooded (conventional) lead acid battery

Varta recommends to charge these with I=0,1C to 0,15C, so between 7A and 11A

The IP22 12/30 would charge the AGM battery fastest, but is it safe to charge the 70Ah battery in low/night 15A mode? That would equal 0,21C and exceed Varta's recommendation.

I'm a bit puzzled, because the C values in the Victron IP22 manual seem very high:

IP22 12/10A -> minimum battery size = 30Ah (0,33C)

IP22 12/20A -> minimum battery size = 40Ah (0,5C)

IP22 12/30A -> minimum battery size = 60Ah (0,5C)

Requirements for outside cabinet for Multiplus II and SmartSolar

Hi all,

The Multiplus II and other Victron products are IP22, but I would like to place them outside.

I cannot find much examples of people doing that, only some pictures.

My plan now is to find some cabinet/box with waterproof door, and make 2 holes in it for fans to blow in and suck out air. These fans should be temperature controlled (and not running when cold).

I guess the next big topic is condensation. This shouldn't happen when the fans shut off when the cabinet gets below 20 degrees Celcius. And the Mutliplus will almost always be running so there is probably always enough heat to prevent massive condensation.

Anything else that I should think off?

Thank you in advance.

BSC status interrupted ip22


We have a BSC ip22 12/30 set up in our campervan and currently it is charging but going into absorption when it should be in bulk still and then the history says status interrupted and it restarts in bulk. Any idea why? The voltage it is reporting is much higher the the BMV and battery. The BSC also feels quite hot but the rest of the system feels OK. We are charging at a campsite but looking in history it seems it has done it before at other charging spots

I ran the input wires for the Orion-Tr smart DC/DC charger to the start battery and would like to avoid doing the same for the second output of the Blue smart IP22 30(3) charger (to charge start bat.). I assume I cannot just put those wires (output of Blue smart) into the input of the Orion, as start and house batteries would then no longer be separated?

Dual IP22 30A (3) charging 72 (6x12) V pack


I bought an old electrical vehicle (FAAM Jolly 600, looks like a luggage truck on a airport)

Right now there is 6 12 V car batteries in series powering it. The original charger is old and stupid and feeds the (bad) batteries to high of a current.

I would like to see if I can charge the batteries in a more gentle way with 2 IP22 30A (3) connected.

The chargers will be permanently connected and built in to the vehicle, so the series connection between the 6 12 Vs will remain.

From what I read the terminals is galvanic isolated so that would not be a problem?

This way I would get individual statistics of each battery from the app and be able to replace one battery if it’s worse than any of the other.

yes yes I know I should buy traction batteries but they are very costly and then I will not be able to play around with these fun chargers.

Thanks, please write if I should elaborate on something.

Battery charged from multiple sources

Hi I have MPPT charger 150/35 which is Ve.Msart network with Victron battery sense and that was charing until recently one AGV battery 200Ah . Recently I decided to change to LiFePo4 on my boat and after investigation I decided to to order Victron Energy Orion-Tr Smart 12/12-30A (360W) Isolated DC-DC charger the idea behind it is to protect y not so smart engine alternator. So as far as I can see this is not posible to connect the VE.Smart network so it won't be aware of the there charges on the battery . And then I also want to order the Victron Blue Smart IP22 charger will will allow me to charge the same battery usage shore power . That device is also not Ve.Smart network compatible to it won't be aware of the other two chargers that will charge the same battery. The new battery is 180Ah . So my question is can I connect them all to the same battery . Will they be able to charge simultaneously the same battery do I need some smart device between the chargers and the battery to control the power and the cycles . I can't find that information anywhere on the site . I guess the idea of having the VE.Smart network would of solve this issue as they will start talking to each other but at the moment two of those devices are ot sporting it . .

Blue Smart IP65 and IP22 can be connected in parallel with another charger?

Let's say a 12 V AGM battery bank is charged by a big, powerful but terribly inefficient "BULK" charger that runs for a limited time up to 14.4 V Absorption, but this charger wastes 50W when IDLE / Float, even when the battery current is less than 100 mA. The Bulk charger can be set to turn off at end of Absorption.

Could I use a Blue Smart IP65 (or IP22) set to Power Supply Mode at 13.5 V in parallel with the Bulk Charger, just to provide a more efficient Float stage?

Would the 14.4 V Absorption of the Bulk charger cause damage to the IP65 or IP22 set to 13.5V?
