Problems with renogy 170ah batteries

[FishHog]

So renogy shipped me their new 200ah core battery as a replacement for this one and did not want the 170 returned.

While the process wasn’t fast they were easy and good to deal with and I think the resolution is more than fair

Now to go ahead and try this repair on the old one

I also have a similar issue with the BMS. And I just replaced it with JK-B2A8S20P BMS.

I have a few questions.

Does anyone know what are these two white cables marked on P -2? Should I connect them to anything on the new JK-BMS?

Also was there anyone able to fit this size JK BMS into the box? I couldn't fit it so I am planning to place it on top of the box and looking for alternative ideas.

Thanks in advance.

So what was at the other end of the white wires?

I’d guess a temp sensor.

It is glued over the cells.

You are right, it should be temp sensors.

Thanks a lot.

Hello everyone, glad to found this forum, I have exactly the same issue with my 170ah Renogy battery - charges only to 13.3V…

I also plan to install the JK BMS, wich should arrive the next days.
For the package issue I plan to cut a Pocket in the upper lid and 3d Print a „hood“ wich takes the larger BMS. I can make some pictures if anyone is interested, but will take some time.

For those who made the JK BMS swap: is it possible to unpin the cables from the origin bms-plug (balancer leads) and put them in the JK BMS-plug? I can Imagine that the Pins are the same and then you dont have to cut any wires?
