So i finally got the JK BMS data, without having to do any additional wiring. I found a repo, and made some modifications, but largely it works out of the box to retrieve the JK BMS data from bluetooth, and sends it to MQTT which i can read using Home assistant. if anyone is interested, repo is - ht...

So I let it charge last night at max amps (80a set on the inverter) between 00:30 - 04:30 From 30% SOC (5kwh), it went to 90% (15kWh) in about 2 1/2 hours (approx 3am), which according to my inverters battery charge metric is 10 kWh charged. After that it charged very slowly as normal but SOC didnt ...

Checked the voltages on DIY stack and Pylons, they are now the same as reported from HA (pylontech) and the jk BMS (diy). Did not take very long for them to equalise at all. Unfortunately, I can’t check that often as the Bluetooth on the BMS has literally <5 meter range. (Until I get it hooked into ...

Ok just to note for day 3. Batteries are all connected up everything all fine and dandy. No sparks, zaps, burns. The one time I didn’t have my gloves on, I did get pierced by small stranded wire from the battery cables. I discharged the pylons to around the same voltage as the Batteries (approx 49.8...

Kenny, is there any data with your cells that indicate expected cycle life? I see quite a variation when it comes to the EVE 304 cells that I think you have. When I did my research I was looking for 6000+ cycle cells. I believe these EVEs can do this. But I think Colin would have a better idea on t...

Ah you have a slightly different model to mine - I think mine might be older, the silver case style. I think the newer ones are black case. Should be pretty similar though once you find the right port. Did you pay for the canbus extra option? Um, no I don’t think so. I just selected the first and c...

There’s 2 ports on mine The first one is labelled can/rs485. The 2nd one is labelled gps (strangely) this is the 4 in port for RS485 comms according to this. https://i.postimg.cc/G9FbQzS6/1-EC20181-EB9-B-4-D82-960-F-4991-AFE35264.jpg I think it’s one of these connectors https://amzn.eu/d/6K4qPVr, I ...

Here’s a link. It’s the official JK BMS store.

Day 2 Would have finished the job today if i didn’t run out of crimps, just 3 short. Ah well, will hook it up tomorrow. All wired up to the BMS and turned it on. Looks good. The most annoying part was keeping the BMS cables tidy. Next time, start with a good cable management system before hooking up...

Ok so here’s mine, I put mine under the work bench, it’s close enough to the inverter and the pylon and put insulation around the sides and the front when I finish. Figured the concrete floor would serve as a heat sink if it ever gets too hot, but I doubt it would be necessary. Very well packaged, t...
