Please post your settings. You can change the voltage levels that are used to assist the SOC estimate.This is my second year with the battery and it has not caught up.. Still 30% off.
It's easy to change it in the PC app. There is also an option for English.What is this software? Is it Blue tooth or direct connect? I could not find the PC software or missed it in the overkill manual.
I trust the Vivtron Shunt to give SOC of batteries and trust the BMS to keep track of pack voltage and cell voltage And over currents.
=================
EDIT: I now see the part in the Overkill manual about the software for the PC. Apparently it can do this, but the software is in Chinese, and the how to change the capacity is not pictured. I'm unwilling to drop money on the PC connector or download the software until I have better instructions.
I also see that the app is downloadable from this site:\

Nice. So you can simply wire this directly to the BMS?JBD tools can be set to English or American too.
You can use any RS485 to USB adapter. I like this one because it has visible tx/rx leds.
Stop making excuses, get er done !!!
You need to remove the bluetooth device on the JBD and insert the hardware adapter. I've never used the software, is there any benefit over the bluetooth app? I set everyone up on bluetooth, disconnect and then wire the USB/485 directly to Solar Assistant.Nice. So you can simply wire this directly to the BMS?
I need to order a half dozen if that's the case.
If your exact model of BMS has an RS485 port, yes.Nice. So you can simply wire this directly to the BMS?

None of my JBD BMSs came with the RS485 chips or connector installed on the board.Nice. So you can simply wire this directly to the BMS?

I feel like it's easier working on a PC. You can adjust some additional parameters and save / import configuration files. (the overkill app can do this as well.)You need to remove the bluetooth device on the JBD and insert the hardware adapter. I've never used the software, is there any benefit over the bluetooth app?

I used the Bluetooth connection to connect the adapter, without the 12v+.None of my JBD BMSs came with the RS485 chips or connector installed on the board.
You can buy a USB to 3.3V TTL RS232 converter and use it to connect to the BMS RS232 port. Unplug the Bluetooth adapter and jumper your USB converter in to Tx, Rx, and Ground. Do not connect to the +12v on the BMS side. The pinout is shown on the Bluetooth board.
When you are done, plug the Bluetooth adapter in and your BMS is back to its original configuration.
I didn't say that. I would presume that it would work fine, but you wouldn't be able to use both at the same time. I take that back. Only one device can talk to the BMS at a time, but both could listen.So you can splice the USB adapter into the Bluetooth and use both?
Exactly....Use it for it's intended purpose which is not SOC calculations.BUT, a BMS is purpose is not as a shunt nor have I seen any of them sold as one. The BMS is for protecting the pack and individual cells. As a secondary use, I am depending on it for individual cell V monitoring and that's fairly important. As a tertiary, it would be nice if it balanced effectively and sure, measured accumulated current in and out. But there are good cheap outboard devices that can do that.
I run both in parallel and the drift is always about 7-12% off. Someone mentioned that JDB might use the voltage values in the config vs true measurements. Starting to think that individual is correct.I am very satisfied with my 16s JBD managed battery. Added a Victron Smart Shunt and on both units the current , voltage and power measurements are within 1% of each other.
As they should be.I am very satisfied with my 16s JBD managed battery. Added a Victron Smart Shunt and on both units the current , voltage and power measurements are within 1% of each other.
Both of my Overkill/JBD reset on full charge.For those who say it will reset itself and have actually done the procedure, wht is it? I use the XiaoxXiangBMS APP as I’m sure the OP does, and it has not worked for us.
If there is a simple fix, what is it? I’m on two years and one BMS with everything I’ve tried has not reset it.
It’s something I and many others live with, but if there is another app, a procedure, or anything to calibrate it, would be nice to know.
What is this procedure or how do you access it with what software or app?
How do you confirm the JBD internal calibration.
Mine is off by 30%, and I am interested in fixing that. I haven’t found a thread, setting, or instructions to do that everywhere I’ve looked.
