Victron and BSL Batteries connections

Hi to all,

Received first batch of BSL batteries 48/100E and 48/200PW . Normally used Pylontech UP5000 with our Victron systems . Familiar with Pylon to Victron connections with Victron cable "type A" and "type B" cables for BMS CAN or CAN BUS connections.


On Victron instructions of approved batteries, they now have BSL and say the "type B" cable should be used .

https://www.victronenergy.com/live/battery_compatibility:bsl


I tried all I could . Never managed to see the BSL battery on the Cerbo . tried on a Cerbo S.GX with 500bauds, tried on a regular Cerbo, with TypeB cable, with BSL supplied cable , with regular RJ45 cable .... Don't see it >


Any help greatly appreciated .

If you scan the bar code on the front of the bsl batteries they link their manual with step by step instructions as well.

Are you trying with just one battery first or a few? Have you definitely connected to the can on the battery side?

Other thing to note they don't like the rj45s with metal jackets.

Thank you very much @Alexandra . I am trying first with 1 battery. This system will have 2 so planning to connect the 2nd once I see it on Cerbo. Will try to scan later today. Thank you. Yes on CAN port of battery. I may have forgotten to set dip to 1 . Never set dip on pylontech with victron cables connection, but someone told me in another forum that it is a must.

No worries (I have asked a few of my own face palm questions here). Glad you got it working.

By the way @Alexandra , do you have feed back to share about BSL batteries ? Have been happy for many years with Pylontech but the price difference becomes significant .

With warranty. It's great. Total unit replacement. Have replaced 2 units. Some early ones (early firmware) that had issues with balancing and then one cell was not well.

Of the rest of them. SOC does a weird thing (seems to be improved on newer firmware) where 100% is triggered way too early (so jumps up) when charging and then the charge current drops off due to cloud cover or grid drops off again during charging.

Also don't charge too fast (50% of discharge) they can't balance fast enough. They do mention in in set up on the charge current.

Otherwise adding to existing banks. Other than different terminal sizes and dip switch number has been ok. And trouble free.

Bigger banks behave better. But then we have a bunch of single battery systems that have been solid since the beginning. So they are ok. Not premium but do the job. To be clear though we mostly fit the 7kWh Bulls. 135AH cells.

@Herve RV Nizard I have 8 fairly new BSLs. I think the model is 48/200E. So far they are fine.

Previously, I had 8 pylons. They were installed badly and the boards burnt.
