6++ months of daily storage on-board – Monitor your batteries 24/7 with –
- Auto setup depending on how many batteries are on the pack (up to 16)
- Each battery is monitored , graph ease the way to detect anything is wrong
- tired batteries – battery under / overcapacity specs
- balancer malfunction ( MOS broken or bad wiring )
- Every anomaly on you battery pack you find in a second!
- SOC is monitored as well and synchronized with battery status
CHARGE-DISCHARGE current [I] cycles shown daily
PASS-THROUGH
- DALY Smart Bluetooth WiFi or BLE dongle, can be connected too and works in parallel
- JK extension connected to GPS Port can be used as well*
PACKET SNIFFER between Bluetooth LE Dongle and DALY Smart BMS
- Possibility to inject command to DALY/Hi & JK Smart BMS via web page
Virtual UART ( over TCP) to use BmsMonitorVx.x.x or JK equivalent sw via internet
- Manage advanced parameters using DALY / JK SW wherever you are !
WEATHER FORECAST and SunRise/SunSet based on your coordinates
- TimeZone detection based on your coordinates
UPGRADABLE platform for improvement – and I release many …..

COMPATIBILITY LIST:

DALY – NEWER & CLASSIC Models with UART(1) Interface are supported and reported as working
JK-BD6AxxS-10P / JK-BD6AxxS-12P / JK-BD6AxxS-15P/ JK-B1AxxS-15PJK-B2AxxS-15P/ JK-B2AxxS-20P

WHAT YOU NEED :

To build for JK or DALY ( New or Classic connector ) the process is about identical . Of course, you have to purchase different cables as listed below

PROGRAMMING :

1- download NODE-MCU-FLASHER here
2- unzip the content where you want
3- find the .exe file ESP8266Flasher.exe it is under “nodemcu-flasher-master” / Win32 or Win64

https://www.dalybmswifi.com/wp-content/uploads/2024/05/image-9.png

4- download the latest ScanLabs dongle FW from here
extract the zip – at this point we need only the .bin image

5- open ESP8266Flasher.exe -> CONFIG -> Gear Icon

https://www.dalybmswifi.com/wp-content/uploads/2024/05/image-10.png

6- Select the .bin file for JK or DALY/Hi – do not worry – if you are wrong at this step you can re-flash using the right binary image.
DON’T use binary images from others – I won’t help further then
DON’T – DON’T – DON’T – DON’T – DON’T change 0x00000
>>>>> if you change it -> you waste the dongle <<<<<<<<<

7- Go to “OPERATION”

8- Select the COM port to which the dongle is connected to the PC – if NO com is listed you don’t have the right driver installed – go to Troubleshooting and install the COM port drivers

9- this is the moment to pray – Flash procedures starts – if everything is ok you will see AP MAC and STA MAC Populated , a QR CODE and a progressing BAR

https://www.dalybmswifi.com/wp-content/uploads/2024/05/image-13.png

9- Dongle takes about 1-2 minutes to complete the process. WAIT until full Bar .
At the end reset the dongle using the RESET BUTTON

https://www.dalybmswifi.com/wp-content/uploads/2024/05/image-14.png

10- Being the first time Dongle breathes, it will start as “Access Point” and in Factory default .

First step is to join the WiFi Access Point “SmartBMS.it”.

Browse to page http://192.168.0.1/upload

Upload the “web-X.Y.Z.all” set of webpages you find in the zip file downloaded.

11- At this point you downloaded FW and Webpages . Follow the instruction on “smartbms.it” to configure

NOTE: un-licensed FW is full-functional – BMS / MQTT and MODBUS polling/publishing time have low limits and only current month of data battery logs are available. If you want to purchase a full SW license follow the page and instruction by clicking on the “UNLICENSED” link when it appears.





STEP 1: ORIENTATION
STEP 2 for DALY BMS: BEND THE NEEDED PINs NOTE 1: PINs are bended with an angle of about 45 degrees – Why? See next pictures .This is NOT a must to do, is simply a way to speed up the mounting process NOTE 2: if Pass-Through feature is not needed – you can SKIP to bend pins 9-10-13-14 ( ref. Pin 1 is top right on the image ) and pin 13 on the left strip line
STEP 2 JK BMS: BEND THE NEEDED PINs NOTE 1: PINs are Bended with an angle of about 45 degrees – Why? See next pictures .This is NOT a must to do, is simply a way to speed up the mounting process NOTE 2: if Pass-Through feature NOT supported for JK
STEP 3: ALIGN ADUM1201 and Solder IT ADUM1201 – G1 to 2^nd PIN of NODEMCUUSE ADUM1201 CAPS to place it
STEP 4: SOLDER ADUM1201 to NODEMCU
STEP 4A: ONLY FOR JK add Connection to GND and VCC Pin NOTE : Agree – in this case ADUM is not really Isolating – or – is partially Isolating . This is the quickest way to cabling and let NodeMCU to boot.

STEP 5 DALY BMS: CONNECTORS FEMALE Connector is a MUST – WiFi Dongle “talk”with DALY BMS through this cable.Central PINs are not Needed – REMOVE THEM MALE Connector is OPTIONAL and Needed ONLY if you want to use the Pass Through feature	Mandatory FEMALEOption MALE – PASS THROUGH-
STEP 5 JK BMS: CONNECTORS ATTENTION! PIN SHOWN in Figure is a VBAT voltage ( on a 16s is around 50v ) You cannot use it unless you know what you are doing . Better to remove 😉
STEP 6 DALY BMS: CABLING DO NOT MIX CABLES – FOLLOW THE IMAGE
STEP 6A DALY BMS: CABLING OPTIONAL “PASS- THROUG”
STEP 6 JK BMS: CABLING DO NOT MIX CABLES – FOLLOW THE IMAGE
STEP 6A JK BMS: CABLING OPTIONAL “PASS- THROUG”	TBD
STEP 7 DALY & JK : OPTIONAL “PASS-THROUGH” Add a 10Kohm to 15kohm resistor between 3V and D2 NODEMCU Pin

DETAILED VIEW of NODEMCU V3 and ADUM 1201. NOTE: NODEMCU comes with different USB-UART chipset . It does not matter which Transceiver you have as long as you are able to program the binary file provided.

FOR DALY BMS Daly BMS come with two kind of connectors. DALY NEW ( little 8mm ) 6pins JST GH Series 1.25 DALY CLASSIC ( larger 13mm ) 6pins Micro Mini JST 2.0 PH	NEW DALY 6pins JST GH 1.25mmCLASSIC DALY 6pins Micro Mini JST 2.0 PH
