As best I can tell this unbranded/generic BMS has alternately been called the 'Battery Hookup BMS', the 'DYKB BMS', and 'Overkill Solar BMS,' which all refer to specific sellers not the manufacturer or model name (JBD-SP04S020). The manufacturer appears to be JBD / Jiabaida, and the model # is JBD-SP04S020. Forum megathread can be found here, and video of the BMS here.

If your BMS looks like this:

With a Bluetooth app that looks like this:
4


And references JBD, Jiabaida, or Xiaoxiang, and/or LLT Power or LithiumbatteryPCB your BMS is likely the JBD-SP04S020 or a close cousin.

The "Ant BMS" is an unbranded/generic BMS is not always easy to identify. It is sold through the DYKBhuang store, ICGOGOGO store, and others on Aliexpress and Ebay. Sometimes "Ant BMS" is printed on the PCB or on the label (or a little Ant head logo), sometimes it is not. Usually it is not mentioned in the product description or title. The Bluetooth App (I am told) references Ant BMS. Forum discussion of Ant BMS here, video review here.

There is more than one model of Ant BMS. Used here (and generally on this forum), Ant BMS refers to the one pictured above and featured in Will's video here. It can be identified by its balance lead connectors on the short side and flat rectangular heatsink.

There is another BMS by the same name (see here), which has the balance leads on the long side, and is often referred to as 'Ant BMS 2019 version' or 'new version'. To my knowledge, no forum members have purchased or tested this version of the Ant BMS.

update: there is an alternate (3rd party) app available in the play store for the ant BMS called VBMS (not sure if its available for apple). It is a paid app.
Chargery BMS is a BMS that uses external relays to control current. It can be purchased through Aliexpress, through forum member @Craig, or through other channels. Forum megathread here, critical discussion here video review here and followup here

The Electrodacus SBMS0 is an innovative open source, open hardware BMS created by Dacian Todea 'electrodacus'. To learn more or purchase see here, for a video review see here, for the forum megathread on the SBMS see here.

The distinguishing feature of the Heltec Active Balancing BMS, is that it is the only commodity FET based BMS I am aware of that does true active balancing (i.e. transferring energy between cells, as opposed to burning off energy from high cells). It can be identified by the black metal case with either capacitors visible on the front or a cover over the capacitors with a QR code. I believe it is sold unbranded to some resellers, but can be bough directly from Heltec via Aliexpress, Alibaba, or Heltec-BMS.com. Heltec sells many other BMS, including high current models, which do not have active balancing but may be worth looking into. They also sell active balancers ("capacative" and "inductive").

Heltec, is also known as Chengdu Heltec Automation co. ltd., Heltec Automation, and Heltec BMS. I believe it is also sold under the alternate brand name JKONG or JiKong (with a little cloud logo).

People Voting "other," please specify in the comments what BMS you are using.

Ideally everyone that votes should be making a comment with this info:

It will help others who are searching for a BMS to see what others with similar systems/needs are using, and help us all get an idea for what BMS' are most popular in this community.

Got 2 Chargery systems in a couple of RVs.

4s configuration, 180 AH for both
Max current is 160 A for one and the other < 20 A
BMS is used as the primary disconnect, the BMS has the smarts
Excellent product
