I'm just updating because so often I find a thread that would have been useful if the person updated/reported back -but didn't.
I've slowly been creeping up my charge and float voltage, keeping an eye on when the runners run, turning down the bulk to 5a charg (because that's what my active...
It's all about economics. I am getting a divorce and spent what I had on what I could. I am full time boodocking/drydocking with a 27' Jayco that I remodeled the bedroom in and converted the bunkhouse to a work room, new roof, 2100wh panels on top, 14kwh eve280's for the battery, victron stuff...
I used my credit union's credit/bank card (mastercard) and my bank is *really good* about fraud/etc
Now I"m chomping at the bit to get these other 2 boxes ups delivery today. I got 5 of them yesterday.
I made the mistake of not top balancing
YES YOU SHOULD TOP BALANCE!
Apparently the daly bms only burns of tens of milliamps from each battery during balancing: if you have a 280ah cell out by .1v, that will take days to balance out and that cell will be higher than the rest, running the risk of...
OMG
I'm learning so much about fraudent qr codes
here is a comparison of one of my batteries qr codes against a genuine eve grade b qr code
and the AUDACITY
My sales agent is telling me that my qr code is the same as all the other qr codes and posted the other pic
Bruh. You can literally see...
This is about what I'm trying to do
I don't know who I'm replying to with the rest of this info, but I'm not the kind of guy to spend hundreds of dollars on something I can build for 20 bucks. I literally have one and a quarter inch wide by quarter inch thick copper stock sitting right here...
There is a big difference between passing off b grade cells as a grade when there is no differentiation.
It's absolutely fraud to do the same and fake the qr code intentionally
You are entitled to your opinion
I hear you
That's enough debate about ethics tho
Sunshine, I have done no diagnostics beyond monitoring the voltages while charging. I wanted to look around and ask a few questions before tearing anything apart.
Yes, Bob TY
I did use SS studs and nuts and made my own 1/4" copper bus bars with noalox on all the connections. it has been problem...
Mine a re Really similar looking to those. I posted pics of my baateries on 1st page of this thread
Agent showed me pdf for bt280
Made the sales slip for eve lf280k
And sent me probably grade b with redone qr codes
OH, Nah, these are absolutely gonna get installed/used. I already have 16 eve280s that are 2 years+ old. I'm expanding my bank.
The question is if I got what I paid for and if I'm going to get any money back for tye fraud
Thank you! This is exactly what I was trying to figure out how to do! (I am not a programmer! LOL)
I can not wait to try this with my Daly 250 Smart BMS.
Aye. The daly knows if it's charging and 3.4*8=27.2v (my float voltage)(which I may have mistakenly stated as 27.0v earlier). Is something there not correct/adequate?
Also, I meant to ask why you suggested 26.8v float instead of 27.2
HEY!
I'm looking for a cheap way to get my VenusOS (running on RPi) to monitor the voltage of my camper's 12v battery. I don't need a full blown shunt for power consumption, etc: I just want to know the voltage of that battery on VenusOS.
I've googled quite a bit, and keep coming up with non...
The problem with this is needing to keep it on the batteries only after 3.4v/3.5v and above, and only until the cells are balanced for that cycle. You do not want it on while the pack is discharging, idle, or low SOC because it can throw off the balance
I used an active balancer because I did...
I am not new by any means, but I did just buy 16 of these sells and I don't keep up with the Jone's when it comes to what the new stuff is.
I'm just making sure I got what I thought I ordered (which I think I did). Ordered from Dongguan Belifine
Also, how many amps are the stock bus bars...
He said they were Batterotech BLT280's
But they are qr coded (fake) Eve....
I thought they I just misunderstood something.
I still have 1 more box and the bms's to receive
And then I'll lodge a complaint.
Advice on how to proceed with assurance and alibaba is welcome
Multiplus calls for 300 and 50mm2 wire, which is real close to 1/0.
I had several folks in the diy solar forum fb group recomend going 400.
But even then, that's for a catastrophic failure so my trailer doesn't burn down. I'm okay with using a 300a fuse, I'm more concerned about the soundness...
LOL, done!
I don't plan for failure, but I do try to plan ahead! I figured at some point I would have some need for a second balance lead on the pack So I built it in from the get!
I'm kind of leaning towards the balance board over disassembly (still going to read more tonight).
So, with the...
Please don't mistake my brevity for being rude: I was on my phone earlier with sausage fingers and a tiny keyboard.
This is a new setup that has only been charge cycled twice. I've been watching everything very closely I'm competent enough to attempt this, but it's still new to me and I lack...
It's also funny that you should say that 1/0 wire is too large for a 300 amp type T fuse... 90% of the 300a-400a holders I found were for 4 gauge wire!
Cool, but I don't want hot wires. Increases resistance and wastes energy as heat.
Is there a standard method to up gauging the leads on these, or am I going to just have to get inventive?
I'm not even sure how the stock leads are attached: are they crimped and shrunkwrapped?
I scanned 1 cell with my camera earlier and it just brought up an alphanumeric string.
EDIT Yep! I just decoded it at power gobel or wherever and it looks right.
Very cool.
THANKS Y'ALL FOR THE CONFIDENCE!!!!
Is there a setting to stop the sinowealth driver from misreading my usb gps and throwing high/low voltage warning codes?
I have a multiplus and bvm712 connected with victron vebus cables to a venus pi. I have a ublox gps connected by a ch340 usb converter to the pi, as well. It works great!
I...
I ordered the Light Board and hooked it up, but my bms is located under the bench seat, so I'm using a usb 3.0 extension cable to move it closer to my other power equipment. EDIT/UPDATE 2.0 cable will not work. I just tried one of those too.
It was slick to use an off the shelf component for...
If you want to setup, manage, monitor, or otherwise access your victron equipment then a Victron Cerebo will let you do that with Victron Connect or Victron Remote Management as will the Victron CCGX (color control gx) which also has a built in LCD
Yes, I have a BMV712 (I think it's a 712. 750...
