The problem :
1) i reset the bms, with the push button,
2) i can see the bms in the bluetooth list,
3) i can connect it,
4) after few minute the connexion is lost,
5) when i go back and launch the scan to reconnect the bms does not appear,
6) impossible to get connect until reset.
Please help me
I have a gap between cells arround 0,1V.
I was guessing the BMS will balance step by step.
But the balancing dont start.
I modify the starting voltage balancing at 2,5V.
But still not work.
I d like to know if someone have an idea about what is going on.
ThX.
1) i d like to know what i should buy to connect my JBD 4S 120A BMS with 485 ?
2) How should i connect ?
3) Does it allow to monitor several BMS with the same connexion ? Is it supported by th soft.
Thx
I d like to know how to connect 4S 12V 250A R05 Daly BMS in network.
UART is it possible ?
485 is it possible ?
Can is it possible ?
Which software ?
Until now i was never able to use PCmaster.exe to get connected, i only succeed with BMS tools, but i did not find how to connect several BMS...
No my cut off is 2700 mV
It is why i dont understand.
An other thing i dont understand is why the cu off is not stable.
I imagined it cut and will restart only if the tension raise a minimum.
But seem dont work like that.
I have the same issue on charging the cut is not stable.
Do you know...
i am doing discharging test.
At a moment the discharge is interupt by the bms, the status change from 404B to 249.
I dont identify something special on tension, temperature ...
Do you have any idea.
If you do so as soon as the charge decrease a little the charger, restart immediately to charge, so if you have a lot of sunshine the batteries stay near 100%.
I wonder if it is good for batteries health?
My charger deliver 13.80v so 3.45v per cell.
Which value i should set for the end of charge.
Lower to cut with bms 3.40v
Or higher 3.50v to keep charging with charger.
Thx
Start loading or discharging the batterie it ll activate the bms.
An other way is to short cut 2 pins called key.
Search on the forum you ll find pictures.
I d like to know how the daly bms work in front of charging and discharge.
1. Who decide the end of charge? Is it the bms ? is it the charger? How does it work? Criteria what happen ...
2. If the bms cut the charge process, is it still possible to discharge in parallel?
3. When the charge...
I have daly bms 250A 4S 12V BT
SH39F003
I tried to connect the bms with the computer, i can activate the port but it seems i cannot communicate with the battery pack.
Do you have any idea where it come from ?
