1) android app ANT BMS?

Answer: MaYi BMS app

Password may be 0000 or 1234.
The blinking light indicates ON, changes to solid when connected to BT.

210809: Unit is displaying valid cell voltage and temp values, but any entry in the parameter 1 screen (all zeros) won't stick. Perhaps due to "WireDisconnected" error but all wires ARE now connected per diagram.

2) My 24S 300A ANT BMS has 2 banks of 12ea SL 104RONS EL1E53 C MOSFETS. The 2 banks allow current to flow both ways, one for load and the other for charging. I need to know how much power these dissipate. Can anyone find a datasheet on these (I can't)?

3) if the dissipation is low enough, this BMS could possibly replace the contactor in my electric micro-van, because it might use less power than the 8 watts the coil consumes. Is that impossible? (Probably not a good idea: MOSFETS fail shorted and contactors (except when contacts weld) fail open.)

There is a fair amount of data on this sales site:

Warning: The ANT BMS current rating is for peak current. The continuous current is always a *lot* less. As an example, the 8s to 20s 400A model is only rated for 150A continuous. You pretty much have to contact the seller to find out what the continuous current rating is for any given model.

If you contact whoever sold it to you they should be able to give you a link to the SW.

You might check this thread out too


I don't know about contactors in microvans so I can't help much.
 
Hi All,
I'm using the new ANT BMS software version and I have a question related to a voltage parameter setting, specifically the one that says " Level 2 cell high protect" ... what this option means? I'm confused because there's already a cell high protect option, but level 2 means? Thanks for your help guys !
 
Hi All,
I'm using the new ANT BMS software version and I have a question related to a voltage parameter setting...
What is the version number of the "new software"? If I can install it and it works, I may be able to help you out with this.
 
Does anyone know if you can hard rest the firmware? If you can, does anyone know the specific rain dance I need to know? I accidentally lost killed the app mid firmware update and bricked the newer 2021 ANT 400amp BMS.
 
¿Alguien sabe si puede descansar el firmware? Si puede, ¿alguien sabe el baile de lluvia específico que necesito saber? Perdí accidentalmente, eliminé la aplicación a mitad de la actualización del firmware y bloqueé el BMS 2021 ANT 400amp más nuevo.
Hello good, friend, could you solve the problem, something similar happened to me, I went to update it and the bar that must be filled did not come out, and now it does not want to turn on
 
Here is a link with a bunch of downloads for the ANT BMSs.


Warning: The page does not work with firefox.... I got it to work with MS Edge.


The page has instruction documents as well as SW downloads.
Seems the page has expired, nothing on it.
Would you be so kind to reupload, if you are the owner....or specifically i need the Ant 7s - 16s manual for setup
 
I have a ANT 8S-20S 300A. I have the software on my iPhone and it connects to the ANT and displays the voltages page (STATE), but I cannot get it to authorize, and allow me to change any settings. That is V1.2.7 ios
I have V1.1.12 on an Android, and that works with the password 123456789ABC . This works the best so far, but I do I do have V1.2.0 for Android but I haven't loaded it, since the V1.1.12 works. I can change all parameters, read the logs (This is great, stored logs), and make changes.
I am using it on a 72V 360A battery pack, with a 72V 200A controller. The ShortCircuitProtectionError popped up and shut down the battery. I went to the log found the error, went to settings and upped the ShortCircuitProtection up to 250A tried it again, and I got it again, upped it to 300A and no more errors. It has been running for 6 monhs now just fine.
The end user has the bike now. We are going to make some more adjustments, remotely. He has an Android, and we want to adjust the max charge voltage for the cells. The all peak out at about 4.120V, so the pack peak voltage doesn't get over 82V. We are going to to tweek that up just a nudge. You can watch your battery health by monitoring the cell group voltages. If one group is the first to stop the charge cycle by a bigger spread, and is the lowest before you recharge the pack, there is a bad cell or connection in that group. You have to go in and troubleshoot. Here is some good info.

Hi , New here, came in for some ANT BMS Info :)

@dcoxryton , May I ask where we can download the latest Android App V1.2 you mentioned?
I have V1 for now, anything extra useful in the 1.2?

Also, the https://xj600e.com/2020/06/30/ant-bms-software/ website gives a link to a V4.9.1 on the rjxzstech.com site. Is that from a different developer, or else why such difference in version?

Also I see mentions of a PC SW for the ANT BMS, any idea where that can be downloaded?

Thank you
 
Thank you !
I actually found one labeled v1.2 at the link below. Also has the manual in the archive
I have not installed and tried yet
 
Well I installed the App V1.2, when I open it, it sees the paired BMS, I select it, but the app does not seem to read any of the parameters.
So unless there is something else that needs to be done to read the BMS parameters, it may only be compatible with more recent versions of the BMS.
