nope, that was one of the issues. same adapter started working after I switched to 3.3vThe rs485 port on a jkbms is a 5v level ttl serial interface. If you don't have the jkbms rs485 dongle you need a usb serial ttl interface with 5v level support.
I might not be all 3.3v… just some (or rather another) weird accident.That's really weird ,-) I asked confirmation to the vendor since Iam working on a jk to pylon converter, I wanted to be sure it works with most 8s and 16s jk bms. Are you using the gps port or rs485 port ? With my test bms Iam using 5v ttl, since my host controller is not 5v tolerant.
You need a GX device. This can either be a Multi II GX or another Multi/Phoenix and a seperate GX device like a CerboGX or VenusGX. Or you can install VenusOS on a Raspberry Pi. If you have more items than an inverter in your setup you should already have a GX that control these components.will you need the multiplus ii GX version or will a normal version suffice
Thanks, that will be painful for the wallet, haha. Was hoping when having a RPI you can connect the normal version.You need a GX device.

@Louisvdw can you add connectivity information or (a link) to the first post of this thread? (ie, how to get things into a gx device) it would be great to be easy to find this, as I see others struggling to find it.
not what I'm talking about, so I realize I didn't type it correctly: can you post an overview of what is specifically needed to CABLE the various BMSes to the GX unit. as in, which rs485 converter is necessary for connecting a jk, etc. there are some nice diagrams too from users.GitHub - Louisvdw/dbus-serialbattery: Battery Monitor driver for serial battery in VenusOS GX systems

I'm planning to add that to the wiki for each BMS.which rs485 converter is necessary, etc.
that’s what i was wondering. thanks. (not so much for me but for others. anything getting buried in a thread is only just that. hard to find.I'm planning to add that to the wiki for each BMS.
I just bought the EG4 LP4 12v/400ah. What cable did you use to connect the battery to the GX device? I've read through a lot but that's one of the things I haven't been sure about yet. Any info you can share would be great. Thanks!I just wanted to report that EG4 Lifepower4 monitoring is working great for me. Thanks for all of the hard work!
Now I'm trying to get another USB/RS485 cable for my other battery. I left a message for signature solar on Friday (they sent me one USB cable for two batteries) but, it's probably justified for that to be a low priority request.
It seems pretty normal to need a second USB cable--nothing said I was using both batteries on the same inverter/install site when we ordered two.
I'm using the signature solar cables. One of them came with my batteries, one of them I paid $5 for.I just bought the EG4 LP4 12v/400ah.
