I have connected easysolar II gx with 2 pytes E-box 48100R batteries.
The system is running but in the console of easysolar I cannot get to see pytes batteries. also the system can just discharge the batteries but it cannot charge it.
I have properly connected the can bus to ve-can terminal with factory made ethernet patch cable. i can access the inverter and can set it up i have followed the manual for pytes victron and done everything step by step but still can’t see the pytes batteries. can anyone help please
I also have Pytes, it requires specially made cable to connect CAN BMS to inverter/cerbo/etc. Take a look to battery manual, they have a picture of that. Standard patch cable will not work
Yes, I have later on figured that out that it works with Victron BMS cable that has cross cable pairs 4 and 5 on battery side connected to 7 and 8 on inverter side.
Now everything works as a charm.

For people searching this forum in the future for answers, use a Victron Type A BMS cable for connectivity with Pytes batteries.
Hi @OGPS
Do you have an idea of the cell type and manufacturer inside Pytes batteries?
Also their BMS is a known one or is proprietary?
Thanks in advance!
No, I don’t know the manufacturer of the cells but they are prismatic. They have a proprietary BMS and a responsive product management team that has accepted my feedback and made some minor changes. Their new V5° batteries are even better than their older E-box line. We find them to have great features for the price and are compatible with the grid-interactive inverter brands we use. I hope this helps.

I had a problem with updating firmware, their engineer spent 1 hour with me on call in zoom to debug and fix the problem. They are very responsive and very proactive. Batteries are really cool made, there are a lot of “unpacking” in YouTube so there an ability to see what’s inside. BTW they have a large storage facility in NL.
I have tried to update firmware of the batteries using their hyper terminal software but failed to do so. I am not sure if the issue was the adpater or the cable that I am using to connect, or perhaps the drivers if anyone has any idea…but also the hyper terminal haven’t showed correctly, some parts of the visuals inside the programs were missing.
I was using vivanco it-net usb 3.0 adapter with factory made ethernet patch cable but it didn’t work.
Should I use some pytes original rj45 to usb cable or any other?
Im not using original cable, fairy saying I have no idea who is the manufacturer is. but works fine. can you record the video of your actions with HT so we can debug a bit?
I have filmed a video but am struggeling how to reduce the size of it from 385MB to 20MB to be able to upload it to this conversation.
Upload it elsewhere, like Youtube, and post a link.
Ok I upload it on youtube.
Ok on this video I didn’t know what to do because I haven’t found a manual on Pytess batteries hyper terminal upgrade procedure.
After I have uploaded this video I have discovered the manual for the procedure, so please don’t mind the video.
The link to the manual for procedure https://www.pytesess.com/public/upload/20221012/51ded1e2c911706952805e1432c53a90.pdf
So did you managed to get things done or not?
When you update the battery, disconnect it from the system.
In other words, just the battery and the laptop, like in their procedure.
Also, you may want to go into Device Manager and see there when you insert the USB to serial adapter which COM port the adapter is using.
I haven’t yet as the site is quite remote. I’ll try to go up over the weekend and try to update the firmware. Thanks for the advice, to turn off the connection to the inverter and for the device manager to locate which com port is activated. That was exactly my enigma as I couldn’t figure out on which com port I am connected. As on the Ve.Configure 3 the port selection instantly showed that I am hooked on com4 but on hyper terminal I was plugged in the same port but didn’t offer me the com4 only 1 2 3 and 5…so I’ve tried 3 but as I didn’t have the instructions I didn’t try to input any command into terminal to see if there is any reaction.
Hi @Ursos,
Thanks for the post, I’ve just updated the Victron Pytes battery compatibility guide to make it clearer which BMS cable is required - Victron & Pytes [Victron Energy]
