EVE LF280K in combination with Victron BMS

I’m a beginner in regard to lifepo4 and was wondering:

Is it possible to control a third party 280ah/12v battery pack (EVE LF280 K) with a Victron BMS and hook it up to a multiplus II ?

I ordered the battery pack way before I decided to go with Victron gear and now I’m stuck with it.

Victron batteries only have cell data and send that to the Victron BMS which can be used to control chargers. I don’t know if you ordered a pack of EVE cells or a battery with its own BMS. If you only ordered cells then you will need a BMS. Some can communicate with Victron systems. If it is a battery with its own BMS you can use it without communication and measure SOC with a shunt or a connected multiplus if you don’t have a DC system. But in short, a Victron BMS is used to communicate with Victron batteries and the Victron system.

Owen’s answer is correct, but to make this absolutely clear, the Victron BMSs can not be made to work with bare cells (DIY battery) nor can they work with other manufacturers batteries that have their own BMS.

Hi @Harm

To what are you referring here ?

  1. External/standalone BMS type.
  2. Internal Victron battery electronics, which is also a simple balancing circuit.

Probably if you try to use the external BMS with a different battery, made from EVE cells, will be difficult.

But if you try to use EVE cells instead of “original” Victron cells, I don’t see why not.
In other words, replacing the below shown cells with EVE cells, will work, no doubt, because a LiFePO4 cell is the same.

The above/below can also be an option for you, if you can source a damaged Victron battery to get its electronics…

No need for an additional Victron BMS if you use a Daly BMS with bare cells.
If that Daly BMS knows to communicate its parameters to outside world in a know/standard manner, you just connect it to a Cerbo.
If not, you may source a BMS that knows to directly talk with Cerbo, like the latests JK-BMSes.

Thanks again and I will correct my previous answer.

What I’ll do for now is make a standalone unit of 4 EVE cells and a Daly bms and just have the multiplus charge it.

Wont bother with trying to get it communicating with the rest of the equipment for now. I’ll gather more knowledge first and tackle the communication problem at a later stage

Thanks a lot for the helpful advice and feedback.
