Hi,
I have just install my 16 battery's with the PB2A16S20P and everything seems to be ok with no alarms , in the 4.3" display the battery bars is empty and the % show 69%. Have any one an idea why this happens

Not seen that, what firmware version are you on, 15.17 is the version I am on and 15.23 has just been released.

Did you fully charge the battery?

My firmware version is 15.10 . I am waiting the USB to update the firmware. And also I'm waiting for the power supply and the inverter.

Get 15.24.....15.23 has bug with the LCD display communication.

The screen shot in my previous post is of a battery just turned on and never charged, same has happened on both batteries I built. Turn the BMS on and it displays the 16 cell total voltage and a SOC %. both were at 52.87 ish and showed 69% ish.

I had the same with all packs "at first" but once configured and the settings made, everything is bang on.

TIP ON CONFIGURATION OF BMS !
After entering the top of the Config Screen (# of Cells, AH, etc) goto the BOTTOM of the settings and work your way UP !
That will let you set the dependent settings in sequence so that the values are accepted and not kicked back. You do need to sit down with an image / list of the setting values you want and don't lose track of them !

My firmware version is 15.10 . I am waiting the USB to update the firmware. And also I'm waiting for the power supply and the inverter.

I am using a jkbms b2a24s20p and am getting a simular screen on my display. I've been told I can't upgrade my firmware on my bms, anyone know is there a way to upgrade the display? I had an older display that worked fine til one day it was glitching on the boot up screen.

Also it always boots up in Chinese, and have to switch to English all the time
