Active balancer for 13s?

I don't think there's any soldering there. I use a similar Sunkko battery equalizer model:

The green connector block is a bunch of screw down terminals. So you stick the bare end of a wire or ferrule in each and screw down the screw. The other end of his wires look like a typical JST connector and pigtail. For example:

Or if he created the pigtail himself from a set like:

Bag of JST Connectors

Bag of Small Plastic Inline Connectors (12 pairs) used for throttles ebrakes Cycle Analyst etc.....

ebikes.ca

You crimp a pin on the other end of each wire and stick it in the connector. So no soldering. You could remove the green block and solder directly to the PCB pins, I suppose, if you really wanted to, for the highest A balancing current with the least connection heating.

Then his battery seems to have a typical JST connector for the balance wires going to each p-group.

Hmm I found connectors that look like the ones in your image here: https://www.aliexpress.com/item/1005007029621946.html?spm=a2g0o.productlist.main.1.612f5df0YZXAaS&algo_pvid=e72b293a-dfd8-4302-aa9e-f2f59ee3c80e&algo_exp_id=e72b293a-dfd8-4302-aa9e-f2f59ee3c80e-0&pdp_npi=4@dis!EUR!1.34!1.34!!!10.00!10.00!@2103868a17321776047197848eca34!12000039151204596!sea!NO!167266123!X&curPageLogUid=ShKuywneBgqc&utparam-url=scene:search|query_from:

But I did not find that specific machine/equaliser you have in the picture. Do you have a link to that one or what is that called? If I understand you correctly you have soldered/created an interface between the connector pin of an incompatible connector pin, from a BMS, to those connectors above at the other end that makes it possible to hook it up to your equaliser through that cable/interface? thanks

This seller is legit.I try to only purchase from "official store".It will be on sale in 2 days but full price is $35 USD.

I added active balancer to all my packs

I was using this balancer but it is not very accurate.I don't have the correct connector yet so I use wires to connect

pls test these active balancers if they actually work. There was a video on youtube with a guy comparing several active balancer boards and some of them did nothing at all or went crazy. Don't have the link.
