I am designing the upper computer program, and then I am also contacting the factory to customize the ttl/usb converter. It may take some time. I will reply in time when I have the latest news

yes and sorry After collecting the customer's questions, Mainly regarding the issue of CPUAUX and some battery information loss parameters, the main reason for this issue is the internal chip failure of BMS caused by static electricity, For this reason, our company has rearranged a design and...

This is a sample, which will be sent to the off grid garage test soon. It supports heating and 4S 5S 6S 7S 8s, support 200A discharge/charge current with active balance 1A/2A support RS485... will be soon................

NOTE: For instructions on heating cables, the green 5PIN cable of the heating cable needs to be linked to the heating pad, and the rest of the black and red cables are linked to the smart charger (after the smart charger links the BMS, it detects the temperature of the battery through the BMS...

Not all customers have a good technical base. If everyone operates in parallel and does not have good protection for the BMS and battery pack, BMS will inevitably fail. Then in the future, the reputation of JK BMS will also decline. Compared with sales, we pay more attention to product quality...

We compressed the software, uploaded it to GitHub, and soon the app will be on the Google store. Thank you for your patience

① This is the default RS485 interface, but it is only used when it is linked to specific equipment in China. If you buy an external RS485 module, you need to connect to ② this interface. At the same time, for the current BMS, we b2a24s20p have customized the CANbus function. After communicating...

The first batch of products is about 20, as the first product. The chip does have such a problem. Too high load leads to overheating of the chip. When receiving this feedback, the design scheme is changed in time. Please contact the store to reissue the chip for you. I think you should have...

turn on heating pad based on temperature。

Heat Function interface (Only BMs equipped with heating function can use heating interface) Description of heating function: Battery temperature is below low temperature charge protection, turn off charging, turn on heating. Battery temperature is higher than low temperature charge recovery...

I will share this in the product link. Thank you for your picture, I will share this in the product link. Thank you for your picture, have a nice day

I see that your BMS is an earlier version. After January 2022, we agreed to replace all BMS interfaces with those in the picture, I will contact the engineer to arrange a link cable of the previous interface for you,

DEYE IS already done

This is a B1A8S20P-H. Because it is a sample, the label has not been completely made, so we have to use the previous label. At present, the upper computer program of BMS is still in the process of designing. Over the next month or two, PC programs will be available, and RS485 TO TTL will be...

The first step is to set the capacity of the battery, which is what the capacity of the battery would be. You can set it a little larger, for example, 100AH battery capacity, 120AH or 150AH battery capacity. The second step is to discharge the battery through the discharger, discharge the...

①:CANBUS interface (At present, only jk-B2A24S20P can customize the CANBUS function) ②:RS485 interface(At present, all JK BMS are configured with RS485 function by default) ③:LCD interface(Please check whether BMS has LCD interface before purchasing. If there is no interface, LCD cannot be used)...

Battery management system BMS in addition to preventing battery pack overcharging and overdischarge, Good balancing is required to maintain the consistency of the battery pack. At present, almost all BMS in the market have the balancing function, which is mainly divided into passive balancing...

This is a new problem. We will find a victron MPPT to verify as soon as possible

GPS is relatively simple to use, but at present, we mainly consider the problem of charging. GPS needs an international card, that is, an international SIM card. Like your telephone card, it needs to charge regularly, which will cause many subsequent problems. We're trying to solve it

Maybe we will consider improving this problem. At present, all BMS cable specifications are 7awg, but customers can replace the cable by themselves. For 7awg cable, we can pass the current of 200A in the laboratory

B2A24S20PR WITH RS485 CHIP. same as B2A24S20P add RS485 module
