    Victron VenusOS driver for serial connected BMS available - LLT/JBD / Daly Smart / ANT / JKBMS / Heltec

    3 wires on the outgoing side, 4 on the connector side? Either way, the GPS connector on my BMS is 4-pin, so given that there are BMSses with combined ports, it could have changed somewhere along the line...

    "does have the connector on the one end" Yes, but it looks like a 4 pin connector. Perhaps your BMS has the 4-pin GPS/RS485 combined port, mine has a 3-pin RS485 port.

    Yep, very small. I ordered a set of the cables I mentioned, and the USB-serial converter. Let's see. I couldn't find an 'official JK' thing with a female 3-pin slot, so that puzzled me. And you still need the USB converter after that. When the stuff arrives, I'll let you know, current...

    I've got a PC case fan here as well, but on the female connector, the pin holes are 2.5mm apart. I just checked my BMS, pins are 1.25mm apart, so that won't fit. I did find these, 3 or 4 pins available...

    OK, thanks for the explanation. It seems mine has a slightly different connector on the BMS side and separate ones for RS485 and GPS.

    So the official JK module has 3 wires that go to the GX Device, you intend to use 2, the data wires only? But you would still need to have a tiny connector on the BMS side, right? And you expect the USB port converter to accept the data wires from the BMS? The JK module has more wires on the...

    Right, 3 wires, my bad. From the link above by @jamiegreen - this looks like 2 connections?

    So, that, in combination with this https://nl.aliexpress.com/item/1005003451100409.html?spm=a2g0o.store_pc_groupList.8148356.16.47695b86tNdzqO But the USB-connector has only 2 slots for wires, while the RS485 has 4 wires? (edit: 3 wires, Martijn, 3 wires) You probably know of this makes sense...

    Oh, this is very very interesting! However, I'm confused as to what cable I should use for a JK BMS to connect to my MultiPlus II? Any pointers?

    Daly Smart BMS SOC not show

    You need to set the capacity and charge to full. The voltage isn't a proper indication of the SOC due to the flat curve, so it will use the cumulative discharge current to calculate the SOC.

    24 x 200ah cells to make biggest ah 24v battery.

    It is strange the JK website doesn't list these. HeltecBMS seems to have an 8S version as well. All the JK-variants 8S with 2A balancing are 200A only. I have no idea how they do this. :)

    24 x 200ah cells to make biggest ah 24v battery.

    The Minerals one is also based on JK. I'm not sure how they're doing that, but the HankzorBMS store lists them as "JK BMS".

    24 x 200ah cells to make biggest ah 24v battery.

    Just purchased one from the HankzorBMS store, I was told starting voltage has been lowered to 20V. Checked the manual, it says 20V: https://github.com/NEEY-electronic/JK/tree/JK-BMS?spm=a2g0o.detail.1000023.4.758f6224eNjVM2
