IP22 12/30 compatibility with 100/20 controller?

My IP 22 12/30 has been the only power source charging my 12v Battleborn house battery. It is powered from an inverter connected to start batteries/alternator -works great never any problems, Recently I added 2x 100 watt solar panels in series and wired a 100/20 controller into the Battleborn house battery and if I run solar controller and IP22 at the same time the IP 22 is over heating, it also made a clicking noise. The solar works fine no issues.

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?

Victron Blue Smart IP22 Charger

I have two 6v AGM batteries in my camper van that I want to swap to one SOK Battery LiFePO4 12V 206Ah. I also have a Progressive Dynamics PD-9245C Convertor/Charger that I need to upgrade to get a proper lithium charging profile. Would the Victron Blue Smart IP22 Charger be a good alternative? I like the bluetooth connection as well.

That's a mains powered charger. I also check this one: https://www.reddit.com/r/SolarDIY/materialssupply

Victron SmartSolar MPPT is the solar version. Also Bluetooth. but i think i can't satisfied, Is it good for buying this?

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


Setting I use for the IP22

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?

diode bridge necessary with ip22 charger?

I have a starter battery and a service battery on my boat and need to replace the charger. The old charger has a single output. Both batteries are connected to the alternator via a diode bridge. If I connect both batteries separately to the charger, will I still need the diode bridge? How then does the alternator gets connected without messing things up? Here's an image of the current setup:

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?
