Hi
I'm looking for a BMS for my LiFePO4 batteries which is compatible with Victron Multiplus-II, either over VE.Bus or CANBus.
So far I have only found the REC Active BMS, are there any others?

List of compatible BMS, VE.Bus or CANBus
Hi Asbjoern,
I am moving this to the modifications space.
The only currently supported batteries are those listed here: https://www.victronenergy.com/live/battery_compatibility:start
This appears to have not been updated in some time.
I'm trying to determine if I the Daly "Smart" BMS (With CANBUS) can be integrated into the Colot Control GX for battery monitoring and charging control.
Hi @irwinr
This BMS speaks a different protocol, so a GX device won't recognize them.
This company a has a good range. and they are in Europe. They have a good app which is free to down load and use.
I'm also looking to buy REC Active BMS for Victron. I plan to connect to CCGX and use this as a true SOC Battery Monitor.
I am hoping somehow that it will tell the SmartSolar 100/50 to stop charging when SOC is above 90% or so, rather than just using the Voltage.
Did anyone find that this has worked for them?
I see someone has made a Chargery driver and it is working well.

As far as I know, REC is the only one really. They have good support for Victron too.
Apparently the Batrium works, but I can't be certain. Besides the price of it is rather extortionate.
You can try this company https://emusbms.com/product/bms-mini
Much better pricing and app software.
Recommend then
REC also have 'normal' (non active) BMS options, what configuration are you building? (4s, 8s, 16s, how many Ah)
try 123smart you can use LV and HV but you still need to connect to a VE BMS for the Multip[lus and Quattro interface
I've got the 123SmartBMS. Works well except for the cell balancing which heats up the resistor on the board causing the high temp alarm to trip, cutting off allow to charge signal to the multiplus.... You have to set the high temp higher than it should be so it doesn't cut off charging during a cell balance. Sort of defeats the purpose of the high temp function thought... otherwise fairly nice product.
As a proud owner of 22kWh LiFePO4 and REC-BMS I can confirm that this setup is 100% compatible with VenusOS.
So do i understand right that REC BMS is working out of the box?
wich one is the compatable?
- rec Q BMS 16s
-rec SI BMS 16s?
Hey, are there any news? I'm planning to upgrade to some lifepo4 batteries too. Also have a mppt100/20 which works like a charme on venus os on my pi. Would be glad to get some bms into my system showing me the real soc. Kind regards :)
Ta for the shunt info, the IVT-Series is the model you mean? This shunt then plugs directly in to the G1, and not the Cerbo?
And yep, I wouldn't want to pronounce 'sabellenhuette' - But so long as the can deliver to the UK. all is good.
Correct, IVT-series will work. It‘s a can-bus sensor, so you have to include the sensor in the can-bus connection between Emus G1 and Cerbo GX. three wires, ground, Can+ (or Can H) and Can- (or Can L). The sensor needs +12V in addition. You can use the Can2 type of the sensor with no termination, cause you terminate the can-bus at Emus G1 and Cerbo GX. I‘m using the U0-version without any additional voltage sensor.
You can ask Isabellenhütte to recommend you a dealer in UK, cause they won‘t sell to end users directly. I‚ve paid 160 Euro plus VAT, plus shipping for 1 pcs. Not the cheapest sensor, but very good quality and precise.
Good luck...
Hi are there any updats to VE.Can BMS's
Hi,
I saw in this post that it is possible to connect an Emus BMS G1 on a Victron Cerbo GX system. I am in this case.I would like to know what the procedure is.
I have performed the following tasks :
- updated my firmware with version 2.9.2 file: EmusBMS_m1284p_v2.9.2_Victron.img
- connected the G1 BMS Control Unit to the BMS-can output of my Victron Cerbo GX via the CAN and - CAN + and GND outputs
Is there anything else to do so that the EMUS G1 is seen by the system Victron Cerbo GX system ? Because I do not see it ... Maybe it's my cable? Do you have a plan of the cable that needs to be made ?
Thanks for your help
Emmanuel
