Thanks Grizzman. That all make sense to me.

Hi, Yesterday I connected my pack in series and started charging. The BMS came on after I fixed a bad connection on one of the sensor wires. (It is a very thin wire so shit can happen when you crimp) everything is working fine. I use the Bluetooth interface for programming. When I stop...

Another question. At what voltage does the BMS start balancing? Can you change the voltage levelfor balancing? My button for balancing is not activated. I can notactivate it?

Hi Otte, I have the same BMS you have in your pictures. The manual that was included was for another BMS. Do you explain where to connect: Bluetooth module? USB cable Temp sensor?

I watched Will on one of his Youtube videos. His recommendation was to use the resistor on the negative side? I have always done on the positive side. Does it matter?

Well I have not tried to connect with the sinowealth software yet. Did not think it was so important to get the readings right in the BMS. But I’m starting to think it also affects the balancing. In the end of the charge cycle when charger goes in to absorption the balancing stop when amperage...

That is one way of doing it. I was thinking installing the DC/DC charger in the trailer with Andersen connectors on both input and output. Makes it easy to move it to the truck If I want to charge my portable battery. And when charging the trailer battery while towing I just leave it in the...

They are in service since a year. Have no problems. My question is more academic in order to understand what you can expect if buing matched Grade A cells. I think the seller was Varicore.

I would buy an SOK if it had a way to connect to the BMS. I can understand that SOK do not want consumers to change settings. But see what is going on is another thing.

Thanks will give it a try! cleaning + loctite primer 494147 + loctite 271

What two pins are you talking about?

Hi guys. I have been servicing a lot of lead/acid batteries in yachts over the years. Most of the time the customer changes his batteries before there is a catastrophic event. But occasionally I have seen lead/acid batteries that have had shorted cells that have caused extreme heat and in some...

How did you balance the

If you do not let the voltage go up more than (3.4V) cells will most probably be balanced. If you go higher you end up in the knee and your Delta V starts increasing very fast.

I finished my compression rack today for 4 x 280 Ah cells. compression will be achieved with 4 threaded rods between two aluminum plates (5 mm) Will use the pack in a travel trailer. I want to reduce the movment between the cells. Do you compress when cells are 10% SOC , 50% SOC or 100% SOC...

Hi, Today I was wathing Will Prowse video on the SOK Battery. I’m amazed that there is not a similar battery box available for the EVE/Lishen 280Ah cells. How cool would that be. a Metal box like that with room for the BMS would be a Big sales succes. i would buy one immediately. Another...

Thanks. What is the answer. My rods are M6 stainless steel?

Yes it was no difference.

Well that is a good question. Accordingly to invoice it is course.

Hi Guys, My Daly Smart BMS disconnected today when I did run the coffeemaker. (Second time I used a higher load) I tried to restart the BMS with the wake up button I installed. No success. Started a charge cykel with the battery charger. BMS came to life and let current thru. Only problem...
