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...
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...
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...
So, that, in combination with this
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...
Just purchased one from the HankzorBMS store, I was told starting voltage has been lowered to 20V.
Checked the manual, it says 20V:
'balance slider' > it's not an interactive slider, but an indicator showing the BMS is balancing the cells
'cycle count' > going to (close to) 100% and going to (close to) low voltage cut-off and back up.
Mind you, the specs say 48V. The JK manual states that it needs a 'booster' (DC/DC converter) to supply it with power.
I've been chatting with someone from HankzorBMS and they're telling me they lowered the 'starting voltage' for their BMS too. Also a rebranded JK.
I would like to oversize a bit, a 250A would be ideal... I destroyed my rebranded Daly with a...
As Andy was testing the 48V JK BMS (click for video) on a 4S/8S system, you need a DC/DC converter.
But, he also has a link available for an 7S-8S 24V BMS with 2A active balancing, see second entry:
I have a Victron MultiPlus 24/3000 as well, but as far as I can see, the battery cable (from cells to shunt/connection and then to the MultiPlus) can be 50mm2, cause you're way below 5m. Or am I missing something?
