Seplos CAN BUS RS485 48v 200A 8S-16S BMS

should I also be mindful that the discharge/charge specification of DIY#1 EVE and DIY#2 LISHEN lifepo4 batteries be the same? Or it will not matter as long as their capacities are both the same? thanks
there is so little difference between manufactorers it shouldnt matter, besides this bms has voltage and amps regulation ( as precharge resistor)
 
if calibrated properly, the bms will do that for you, and much more fine grained ( as in 279 ah etc)
i have a problem that inverter show the pack as fully charged 100%(connected to bms thru can) so its not charging.. i stated to top balance..and it still charging since two days..
how to reset the bms soc?

Either use the PC software to change the SOC, or complete the top balance and then re-attach the pack and let it self calibrate
 
can i top balance to 3.65? as i have a 3.65 charger only
You need to puy all your cells in parallel, and use your CC CV power supply to charge all the cells to 3.65V, while amps go to zero or close to zero. Then you can let the rest, and re-configure to a 48v bank.
 
I am finding that my cycle count is increasing at twice the expected rate. Every discharge to 16% and charge to 98% increases the cycle count by 2. Anyone else seeing this?

same here!!! did you top balance? charge discharge full cycle?
 
Yes and yes. I found a setting called cumulative cycle life capacity which is set to 20%. I have changed that to 80% which may fix it.

i think your setting now is that when the battery reach 80% (from 100%) will count as one cycle? hope am wrong
 
Hi friend,
I have 2 battery banks and connect paralle, ( Setting dip switch is needed)
If use Can port to communicate with Inverter ( RS485 port can comunicate with pc to monitor) - Dip switch set follow Can dip address table
Or must set follow RS485 dip address to communicate with inverter and PC to monitor
 
Ray Builds Cool Stuff
is my youtube channel. Thanks for your support.
I've just found your channel a couple days ago Ray, it's now my goto channel for battery building (sorry Will ?). I like the unedited footage, warts and all. I've only watched one of your videos so far (everything else is queued up but so little time...) and I've learned a lot of seemingly minor things but which actually make all the difference.
 
Mostly, my latest shipment was sent by DHL instead of fedex. DHL is terrible. It took many days longer. I still have not received one of the four BMS from the last order and tracking shows it held up in customs in Cincinnati since November 30. Adam says it is ready for delivery and DHL shows nothing. Of the three that I got, DHL showed it out for delivery 3 days in a row before I called them and it was then delivered that day. I got an email about buying one of their ready made batteries from Adam's email address. I asked if he sent it and he said he did not. That may or may not be true.
I got an email from Adam that went in my spam folder, saying his email had been compromised and he had a new address.
I think the old one was adam@seplos..., and the new one is adamhan@seplos...
For those using Seplos products, was the company honest and professional? I ordered four Mason batteries, two 200amp BMS's, and. JASN busbar, totaling around $7000 in Sept.

Its been over 90 days now, and I have received nothing, and they have been VERY evasive in providing different stories, and incorrect shipping info, no copies of shipping lables, and just keep saying they will "push their forwarder" for information. I did not use the scam email, and dealt directly with the company using chat on their Alibaba site. I used credit card, and Alibaba processes.

I am getting concerned at this point though, and my options are becoming limited due to my waiting, as I know logistics is screwed up at the moment. But 90 days and counting? Have your experiences been better?
I know others have the same concerns as I at the moment, and I dont want to bad mouth the company yet, but I am getting concerned, as thats a lot of cash to loose. The good news is Adam did provide shipping lable proof of the busbar, but thats it.
I ordered a BMS through email, paid via paypal, and received it in a couple of weeks.

I heard back from Link at Seplos. The cumulative discharge capacity setting should be set to 80% to reflect one cycle at 80% DOD.
 
Has anyone received a BMS with 2 cut wires on the white battery connector? See photo. There is nothing in the manual about this. I have emailed Adam Han and not got a response yet.

@Seplos Chris Ren do you know anything?

Just a quick update. I finally received everything I ordered! All ship shape and bristol fashion.

You should contact them and ask them to send a replacement harness.

Well you were right, I got a reply and apparently they sent me a 14S harness by mistake. Who the hell makes 14S packs? And why do that? Wouldn't we cut off our own 2 wires if we decided to build a 14S?

@Seplos Chris Ren FYI.
