Is anyone aware of 4s JBD's that support series connections?

Tldr - will this or any other JBD's support series connection? (I know the description states series but I'd like real world confirmation)
US $30.93 29%OFF | JBD BMS 4S 12V For Lifepo4 Battery 50A 60A 80A 100A 120A With Drop Protection Optional Heating and Series Connection Lifepo4 BMS

I ordered 2 12v 100ah sok from the savings shack with the initial plan to salvage the cells and make one 8s pack for an old system. I'm now thinking it would be a lot more useful to keep the 2 12v packs and use a BMS that supports series. When I don't need the 24v system I could use the 12v for a tank sprayer pump, diesel heater, etc.

Thanks.
 
Well after way to long searching I have came to the conclusion that JBD 4s can be ran in series up to 24v. I suppose I'll be a guinea pig.
 
the 150A can do 4s, but the 200A can not, unless you order the special version:
 
Thank you @Alkaline.
Now I'm realizing there are 2 JBD storefronts on Ali...

For any others, I'm told this supports series up to 4s /48v. Waiting on reply on others.

Searching for JBD on ali is a huge PIA so many sellers all saying they are official store LOL :LOL:...

Hopefully you find the right one.
 
This is what I bought (X2) to make two 12v 100ah be series connectable for 24v (trolling motor)

Irony is, I bought a 12v trolling motor in the end, but the BMS seem really good so far! ( I upgraded from another smaller not so good JBD BMS, so was an easy swop over!)

I can confirm this one is the correct store front if you want a JBD BMS.


I've ordered from them multiple times, and they will customize if you place a large enough order. Very prompt shipping as well.

I can confirm this works well up to (and including) 4 in series.


Look for this in the specifications:
Application: 80V withstand voltage
 
Ordered two of these, will report back after snail mail arrival.

These delivered yesterday, fast snail.
Now I'm considering aborting the top balance so I can get the packs back together and confirm they work in series.

Link to storefront I ordered from.

I can confirm these work fine in series:


I can confirm (through talking to their Alibaba support, if you order less than 5) that this is their actual storefront on AliExpress:


This DOES NOT support series:


Note that you can order the same model above from their Alibaba store built to be used in series, however you must order 5 or more.
I'm sure that the ones that say "80V" will support in series up to 48v systems.
