Not sure if you can use it in parallel with a DALY BMS with balancing function.
Hmmm, I don't know. Seems to be overpriced for a 8S concept with small LCD.I found another active balancer. It mentioned it will work with other BMS.
why use a lcd when you have your cell, once its up and running are you going to be looking at that lcd ,hell no,you will now and then look at your cellHmmm, I don't know. Seems to be overpriced for a 8S concept with small LCD.
It has a separate power input for the CPU over a buck converter with separate ground. Seems unnecessary with large battery power available.
Mosfets are very small to drive 4-5 Amps. If very low RDSon, ok. I doubt this small 2 coils can transfer 4.6A and they are the only active components.
I think it's best to go for a decent BMS with display /BT or wifi to see cell V and an active balancer based on coils. The balancer does not need displays as you get these info from the BMS.
I do not say these Broodio's are the best but you can parallel 5 8S units for the same price and have 5A balancing without loose power supplies and much extra needless wires.
Have you checked the voltage at each pin in your connector?I have checked that the balance leads are all ok and in correct order.
Have you checked the voltage at each pin in your connector?
Pin 1 is negative, work your way from positive pin 2 and see if there is an unusual progression. Voltage should increase about 3.3v as you progress across pins on the connector.
Chances are good you can narrow it down to a single cell. 3v missing likely 1 cell with an issue.
Isn't the Daly BMS the one you need to touch P- to B- the first time to wake it up?
Is this a brand new BMS ( never used before) or did it use to work and now does not.It is awake, not the issues I am having. Thanks though.
So the battery voltage (“at the pack”?) is 3 volts less than the charge voltage?Measuring at output of inverter I get 57v and when I measure at the pack I get 54v.

Maybe this is just charging. Does the battery voltage go up after a while?
Do you have a way to check the current to the BMS and from the BMS?
Seems odd if it were a partial failure.
What active BMS did you buy and how is it working out?After digging into spec, I do feel the 30mA balancing current is low. My battery is 3.2v 150ah each. I don't see how 30mA is enough for a potentially 60A discharging (48v 3000w) and 30A charging. I just ordered an active BMS with 1.2A balancing current. I hope that is better. My Victron can provide other protection such as temperature, low voltage, over voltage, etc.
I just blew up 2 new Daly controllers by disconnecting in the wrong order. I followed the instructions in connecting in the right order but I didn't pay attention to unplug the other way around. I just wrote Daly an e-mail what they can do about. I'm really pissed of.I am with you 100% on everything except this. Looks like maybe an RTFM error.
Step 1 is pretty clear.
FWIW, the Deligreen one page instruction manual is the best I've seen from Alibaba and Aliexpress by a long shot.
Dang, that is disappointing. I have not heard of problems diaconnecting in the wrong order. Nor do i recall any disconnect instructions.disconnecting in the wrong order.

Do you recall what disconnect caused the problem and how you knew it “blew”?
