JBD BMS DISCHARGING

[DR LiFePO4 Battery]

Hi I'm new on this and trying to do my best, I have a JBD BMS 200 amp,my problem is after a charged my battery to 53.6 the bms start discharging them,i don't know why,I'm going to post some pics so you guys can see and try to help me with it...Thanks from Dominican republic

Is it possible that the cells are just settling?

but you think my settings are correct and another thing i only can charge the battery at 5 amp,what do I need to do to raise the amp charging??

I can't map your response to my question.

sorry but i don't have any idea about if the cells are settling

I see your pictures now, they didn't show up at first.
I see that your bms indicates that your battery is being discharge at ~2.7 amps.
Try turning off the discharge path and see if it goes to 0 amps.

I did it,it went to 0 amps but after i turned it on again discharging at 1.02 amp=54 watts

Please post a picture of your setup.
It seems like there is a ~1 amp load on your battery.

What charger do you have? It looks like its only ever been charged up to 53.5V which is about 80% fully charged.
Your BMS setting are pretty standard for default settings. I like setting high cell voltage a little more conservative at about 3.63V and low cell to about 2.57V.

Your battery looks nicely balanced.

If you are using a charger with alligator clips, replace those with ring terminals.

A pic, as John From suggests will let us see what you have much better.

Do you have an inverter connected and turned on? That might be the idle consumption of an inverter or something else.

Did you check if the BMS is really wrong and measured the actual current at the output to be 0?

To me, it just looks like something is connected and discharging the battery. I haven't experienced a JBD BMS with this behaviour. Might be if somone messed with the calibration settings to on but I never have seen this

Thank you so much,I did Exactly what you said, I charged the batteries at 54.0v and it worked perfectly,the discharging stopped

Now the inverter is working good....

Glad the discharge stopped but I would not expect charging you battery higher to have that affect.

Keep an eye on it, let us know if it returns.
