Same makers as Xiaonang/JDB/Overkill but they aren’t using mosfets. Comes in 200a only with a contactor for discharge up to 20S. I opted for “express shipping” which they claim means less than 15 days after their 4-5 day processing. They state that you can cancel or alter your order inside the 5 day window at no cost or penalty. We will see once it gets here but thought I would start a thread today to gauge actual time to receive here in the states. Wish me luck.

 
Wouldn't say new to market.

Referenced in 7/2020:


Good luck!
 
I remember reading that thread about the first version with the silver case. According to the manufacturer, this is V3 basically. At least for them. They switched to a shorter black case back at the end of last year and then hit inventory issues early this year like everyone else. We will see when it gets here how it works.

I've used this BMS for a couple of months now, this is the manufacturers site.
I've ordered another one, and it's been backorder for 1 month.

I also have 2 of the 7 s- 20s version,

They are working good.
 
a later video suggested there may be a problem with the BMS.

Off grid garage on youtube ordered a QUCC BMS with that same contactor and he found the relay would not open. So they sent him a replacement with a different model relay. I have one of those on order right now. It uses a EV200HAANA01 relay with economizer.
 
Proof will always be in the pudding I suppose. And this seems to be an "only time will tell" question because I don't think anyone has used one for year yet.
 
So I paid extra $14 for express shipping and it got here today, 1 week after I ordered. Has a new wiring plug I’m not familiar with; a red and black wire with B+ above it, separate from the sense leads. I’ve sent an email hoping to get an answer before I install and test this thing out. Thought I would remark on the speed in arrival though because it shocked me.
 
Some pics with a closeup of the wires in question. Nice 4 gauge wire for the B-/C- main wires

The red and black wire plug is for an external switch to power it off, or on. I've not used that option.
 
this is just rebrand from JBD BMS, nothing new, all the BMS LTT sell is rebrand from JBD.
 
Don't think it's even a rebrand since JBD and LLT are same company. The way I understand it, LLT is the "retail storefront".
