JBD BMS, have found similar here but not this model

[Simi 60]

Have googled the model number and images and have found similar discussed on here but not the same

Can somone who is knowledgeable comment on this please?
JBD-AP20S003S-P20S-200A-B-U

This was suggested by Amy Wan as a BMS for each battery on a proposed 3 X 280ah @ 24v for a combined 840ah system.

Hoping to pull the trigger and order in the next day or two.

Thanks

I haven't yet had any experience with JBD yet, but a few days ago, I just ordered 4x 16s 200a ones (with the relay on them) to try out from AliExpress. Model: JBD-AP2050035

We'll see how it goes. I looked at the manual for this one you posted and it looks pretty decent. I like how it says 'Accurate SOC calculation'.. Saves you from having to buy a shunt if it really is accurate.

Thanks for your reply

Anyone else have anything to say?
Don't be shy (-;

It would help if we knew what your application was.

If that's not enough info there is a full list of what'll be running here

AGM replacement with LFP, fudged battery size initially, want to do better 2nd time around.

Hi We are full time cruisers on a boat that is set up to be away from shore power indefinitely. When we got her the batteries and inverter were dead and on the perhaps false assumption that it was sized correctly, simply replaced with a bit more. 8 batteries replaced 6 and 5000w inverter...

Battery specs do not give an indication of the intended application. Thanks for providing a link that does.

Would you post a link to the vendor selling that particular model BMS? I can't seem to find that one online. Yes, I do see that you posted the spec sheet.

BMS settings do not seem correct. Its for a 20 cell battery with a max cell protection voltage of 4.25. Check you have the correct data sheet, the linked item is not what you need for lfp cells.

7 to 20 cell battery
I will have 8 cells
From the data sheet which was supplied by fendor

JBD-AP20S003S is designed by Dongguan jiabaida Electronic Technology Co., Ltd. It is an
intelligent protection board scheme specially designed for 7-20 series battery packs of start-up
battery and electric energy storage products.

 

[mikefitz]

The cell protection at 4.25 volts is not correct for EVE 280 LFP cells. If the parameters can be reprogrammed then it may be suitable.

And they can be via Bluetooth app so I am told

 

[Simi 60]

Just looked at the specs for this again
I was under the impression that it was 7s to 20s which specs confirm
But was also under the impression it was for 24v batts/charger
Specs if I am reading them correct says no.
Am I missing something?

 

[Simi 60]

Well.......I just spoke with the JBD store rep on AB and when asked for an 8s 24v 200amp BMS it was the above model and documentation they sent.

Questioned them about my concerns with the above screenshot and they assured me that it will do 8s 24v 200amp.

 

[mikefitz]

I think this is the version you need,

7S 8S 10S 12S 13S 14S 15S 16S 20S 48V 60V 72V li ion or Lifepo4 smart Bluetooth BMS support 200A or 300A constant charge and discharge current electric relay BMS - LLT POWER ELECTRONIC

1) Application:this smart BMS can work for 7S to 21S Lithium ion or Lifepo4 Battery ,the BMS can recognize different series battery automatically with different connection methods as we posted 2) Current : Constant current can be 200A or 300A with charge and discharge 3) with Max 160mA balance...

Some of the parameters may/will need changing for the cells and pack voltages. The data sheet shows values for li-ion cells. The LLT Power outlet have different order options for li-ion or lifepo4 .
The documentation on the LLT site suggest the unit auto determines the pack voltage.
Note its a common port BMS with contractor, (power relay) control.

It's designed for 7 to 20 cells. With JBD you can order custom products.
Personally I am not a fan of the single relay/contactor design.

So had my 3 turn up today
Nice looking bit of gear but soooooo many wires for what is an 8s system
Struggling a bit with the manual (of sorts)

 

[Johneb]

Lucky you. You got a manual. I received it with nothing but what is shown in your pick. Trying to figure out how the wiring goes for 8S
