200A JKBMS with new 4.3inch LCD display
HTML-код
- Опубликовано: 25 авг 2024
- This is my upgrade plan for my existing 14KWh battery system. I will replace my existing 150A Daly BMS with this 200A JKBMS that comes with a 2A active balancer. JK just recently released their new 4.3 inch touch screen LCD display and just nice to replace the Daly BMS LCD display.

For the switch, do you know how it operates... when you turn it on, it gives voltage to the bms and when you turn it off, it cuts the voltage? I am asking because I am using this on a cart and was wondering if I could use the ignition to power the bms somehow, maybe through a relay or something, instead of the switch. I'm just curious : How does it turn on the bms vs a regular switch?
i''m not really 100% sure i have not tested switch with a multi-tester. the switch is like a momentary switch with 2 wires so probably you can use normal switches to wake up the BMS but to turn off there is a delay that you need to simulate a 10s pressed or something.
Where did you source the 8S, 18650 cell holder. Can't find anything on Amazon. Great video, really helped me a lot getting my JK up and running.

Sir Nice video !
What happends if both Charge and Discharge is on simuntaiously, As I can see both turned on in the app
Can we connect it to one power source and Load at Same Time
yes. no issue. that's the goal to keep both charge on and discharge on in running condition.
can i enable/disable BMS with push button. I don't want to buy a monitor. If yes please share the connector pin. Thank you
The power off/on button was included with the monitor. Need to review the wiring configuratiin if possible to wire directly to the bms.
Hi! Is there a way to turn off the screen, already turned off the option "always on screen" via app but still it won't go to sleep
mine i dont see any sleep mode on the display.
Hello sir, mine installed ok but chinese language for the lcd monitor.please help.thanks
Hi,is there a way to turn off the LCD screen without turning off the bms? Thanks.
So far not possible but you can add a switch to cut off the lcd power supply that will work.
Hey Bryan, thanks for the video. I am also using this BMS to upgrade my Daly. My lcd (same one) has a switch wired in parallel with the LCD harness. It only seems to fit in the GPS port (the switch), is that were the switch plugs in on the BMS?
the wiring harness is total 5 pins which combined with the 3pin for 485 com port and 2pin for power button. pls check in the video for a closer look at around 9:00 minutes.
Yes, I believe that is correct
Hey Bryan, can you please put the links to the BMS and LCD ?
You can do a search in aliexpress 'jkbms lcd' you should be able to find lot of options just look for reputable sellers. I think i bought from ic gogogo store.
Can you control the charge and discharge on or off from the small touch screen?
Hi, do you know the if the jk-bd2a24s20p is newer or older than the Jk-b2a24s20p? Or what the difference is between the two? Did you purchase the lcd screen seperately? Thanks 👍.
I am not sure on this but they do have different version the one with heat pad function.
HI, Thank you for the video. Is there a way to keep the backlight of the LCD display turned on infinitely as long as BMS is active?
I noticed it is always on as long as you have the 12v external power supply. The other 3-wire cable going to BMS is the 485 communication port that get's BMS Data
@@bryanmendoza2770 Hi,lcd screen work only with 12v power supply or will be feed from bms? If i have 24v setup i have to put an dc-dc converter
@@carlos_sacalul i have not tried 24v to supply the lcd because i'm using dc-dc converter from 48v-12v for usb charger and fan temp controls.
I have growatt spf 5000es inverter,can i connect it with this BMS and communicate with inverter
So far, i dont see any sufficient documentation for the manufacturer about the bms communication port which inverter or protocol is supported to work. If you need those feature i suggest don't use this inverter for now. There are a lot oem server rack batteries now has those communications port that connects to inverter you just need to ask the seller which is compatible to your inverter system.
is that jk Large display will work with 1A power supply?
What is the voltage of the power supply to the screen
i have supplied 12v
@@bryanmendoza2770 max voltage of the monitor can handle ?
I'm a little confused on the LCD. I ordered the display separately. Connected everything up but have the 2 free wires hanging out. Are these power wires and if so how many volts are you using to power the LCD? Is it a separate power supply than the one the BMS is using?
I connected the lcd power supply to a 12v1amp. Its separate power because your battery is usually of higher voltage unless put a voltage regulator. My bms is minimum 7s.
Hi Bryan, do you need to have a charger or load connected before turning ON the bms? I have an 8s configuration and a JK-BMS type JK-B2A8S20P-H. The BMS turns On and light is flashing. But when I opened the app and DID a SCAN I cannot see the BMS device. When I looked at my mobile bluetooth the device is there. It means my mobile bluetooth is recognising the bluetooth of the bms. Thank you.
No, you dont need a load, but the battery must be connected of course. The bms can be started with a charger I have found as I have the same bms as you have and am having problems with the Bluetooth connection as well, but it could be a problem with my BMS as when I start it up it gives 3 short beeps and then 1 long beep. I dont know what is wrong, all the balance leads are correct and it was working for a week prior okay. Any idea’s what that might error signal may mean? Also, my app shows the BMS but it will not connect anymore.
@@evil17 I contacted the seller and told me to connect the Heat Function cable. The RED and BLACK cables must be connected to the charger. It worked! (You dont need to have Heat pad)

Can you please let me know how did you connect the black cables marked P-? And why are there 2 blue cables marked B-? One is not enough?Thanks for the reply
for the purpose of testing i only use 1 wire for (P-) and 1 for (B-). In actual installation you should use 2 wires to carry more Amp load since these are in parallel. The (P-) is your main negative to your inverter or tester(-). The (B-) is connected to the main negative of the battery. The main positive of the battery is your main positive to the inverter or tester(+). So your main negative power supply is protected by the BMS to cut-off the voltage output for abnormalities.
@@bryanmendoza2770 Thank you for help
Just received my JKBMS display however it starts in Chinese . How do you change language?
i think you need to contact your seller and ask for the bin file to flash to English. My unit was delivered in English version only.
Can you also turn off the bms?
Yes. Press and hold the switch couple of seconds. Check the video.
@@bryanmendoza2770 must have missed that . Thanks again
It's just a shame those chinese english abreviations, not intuitive at all ;
like "Vol" ( volume), for Volt, "per mission" instead of permission.. and lots and lots of others,it makes for a bit of an imperfect experience, just sad.
And still after numerous videos and reviews also showing the insides too,over 2 or 3 days... this is the one i will buy tomorrow, in this case, in the 8s, 24 volt form...
