LOL yeh I can solder and so can most others, that's the easy part. What I meant was, not everyone's gonna be comfortable taking apart a brand new BMS that ain't broken. so if we can get a plug-n-play solution, that makes the solution far more repeatable and supportable for ourselves and others...

Didn't want to risk losing warranty by breaking the seal to open them up. Already had to send one back for warranty repair/replacement. Besides, if I take it apart and start hacking the connectors etc, that isn't necessarily gonna help the next person who's not comfortable doing that, so ideally...

so, without the CANbus chip, are those 3 wires just normal TTL serial signal then?

Hmm I must've got a very strange version then? 3 pins on the CAN/RS485 port. measures exactly 3mm apart (so 1mm pitch), and it's a JST GH style socket which is typically only available in 1.25mm pitch. I agree with @Steve_S here - would you guys be able to provide some "pigtails" for these...

I've got the new version (hardware 8 maybe?), cant remember if HW6 is the same, but this is where it gets interesting. It's a JST GH style socket but the pitch is 1.0mm. I cannot find anyone selling a JST GH 1.0 male socket. There are plenty of JST GH 1.25, but not 1.0mm. and it's also a 3 pin...

Yup c#, originally .net core, now .net5. currently only sending a few fields, like %/Ah remaining, current power (in W's) etc. The raw data is sent to influxDB on localhost (skipping messaging), then HomeAssistant+Grafana on another box does my pretty graphs from the Influx data. Future plans...

I'm not using SA (actually I'm just not smart enough to set it up, I'm a Microsoft guy so when i started this a couple years ago, even a bash script was alien language to me, let alone python), so i wrote my own .netcore code that sucks up BLE data from the JK's and PI17 over hidraw (USB) from...

Ahh perfect! I have a couple of spare ESP8266's lying around so I might even see if i can use the GPIO pins directly against the BMS's port. Are you also having the same reliability issues as I have though? I was pushing 150A+ continuous discharge through my 200A BMS (but for like an hour...

Ooooh i was curious about that! So u got it working? I never bought the RS485 module and have always just used BLE. I was the one who captured all the BLE packets for Jblance so I've been using it in production for more than a year now. But recently I'm having BLE instability issues and was...

fair enough, you have a good sized system I believe, your batteries outsize your solar by a huge margin, and your solar outsizes your usage by a fair margin. Hence with that in mind, as I said your system is barely under any stress, so you should see plenty of life left in it. The danger with...

I have a feeling there's a totally different protocol involved here.. What I ended up mapping out was the Bluetooth BLE protocol, which looks VERY different to the official RS485 document the supplier have sent me. Ironically i chose to go the BLE route because BLE supports multi-point...

There's a few things I'd like to pick with your post.. What does that even mean? ma is a measure of current.. not capacity or voltage, that isn't really a measure of health of cells? Health is usually measured as either internal resistance, or variances in voltage between cells, or mAh total...

Hmm the victron is a bit pricy for my needs.. considering a JKBMS which does all of that and is a full BMS is only around $200 shipped. I was hoping for something much less considering i only need it to perform monitoring functions and can even be contactless as I don't need absolute precision...

Hi guys Anyone know of a product (links will be great) that can monitor the voltage AND DC current (in and out) of a 12V bank, wirelessly? (either Wifi or Bluetooth, ideally with phone app, but not a deal breaker if i have to write my own code)... Basically most of the better BMS's already do...

Yup I had another question out in another thread somewhere asking whether it's possible to run a separate active balancer on top of the JKBMS's built-in balancer and whether it'd cause problems... and it seems like the prevailing answer is it'll be fine (even the JKBMS seller said the same thing...
