Yeah I guess the plan right now is the discharge it down a ways which I'm doing right now and recharge it check the voltages on all the batteries probably is going to a assortment of voltages and as I said the eqs taken out even though it was recommended for lithium batteries as well in the...

Any cat5 you purchase will be a one to one.

So was looking at these battery's http://www.powerwholesale.net/catl-lf302-310ah-32v-lithium-iron-prismitic-battery-diy-rechargeable-solar-battery-with-busbar-p-3838.html and unsure of what mppt to use thinking 6kw+ or better , currently no solar yet but may install some so will just use...

Thanks

I left everything on for the night to see if the BMS might raise voltage and balance out some. I took another picture of the bms model number and trying to see if I could find the spec's on it ..... I tried to reset the unit a couple of times but didn't seem to change anything .. The number I...

Well I had discharged it down to 70% via EQ really had all the voltages within a 10th of a volt but not exceptionally very high average voltage per cell was 3.25 area I will post some pictures of the cells after the charge downside I just lost another part of my amp hours it was at 180.5 prior...

Not sure when you say high cells but I have a load tester for 12vdc that would make quick work of draining a 12v set of battery's that I use on testing my golf cart battery's to test load . My original thought was that the BMS should balance the battery's my early voltage checks had 3.5 to some...

so purchase a power supply and charge one battery at a time to 3.65? Should I remove the EQ back off the unit?

I can't remember what video it was don't think it was on this equalizer might have been a balancer that it would take and look for the highest voltage and try to match all the other batteries to it I'm thinking that I'm going to have to get this voltage up to gain some of my amp hours back. What...

So would you remove the EQ and replace it with a power supply and charge each battery and hope the BMS will keep it balanced? As I have showed in the pictures it has been slowly degrading in the few months of operation I rath not have to keep doing this to keep amp hours at where it rated would...

Im getting in same place no help at all just put them in Saturday and have a few issue's on settings and been told to contact thru ebay and have no luck will need to make my mind up in 30 days. I had called several time prior buying and never received call backs should of known. Now I will be...

I have been having issues with mine as well I forgot the first error code it would count down and shutdown but they sent me a main board which was a pain to change on the wall you have take all the boards to install it but they sent it to me free of charge. Now Im getting error 32 code and now...

Thanks for all your input to give u some history I purchased this from a guy that bought a Palat of them brand new... I took it brand new out of the box I felt I got a good deal as a 200amp hour 48v for 1500.00 so some lose of the amp hour I can live with as long as it doesn't keep going down...

Just trying to make a battery backup I purchased a 48v 200amp hour battery . I need minimum 5.5kw with solar input and charger and utility 120v input and need 220v split phase output. Wifi would be good and maybe charge battery control adjustable..... been looking at the PowerMr units but not...

Little more information I did pull the equalizer out and took a few more pictures this might be a pace BMS although I can't quite see all the numbers you get exact match I'm currently running a discharge on it with a space heater and going to let it charge back up again thanks for all the help

Thanks for sharing and very interesting on your concept of doing it.

Thanks for your reply and that was the down fall not much support or information on the battery. I currently have the top off it in the event If I purchase a power supply and charge each battery would I need to remove the buss bars to charge separately? or can you go across each battery in circuit?

I have 2 refrigerators and 1 freezer upright and 10,000 btu window ac and just some general lighting would be my main stuff but have golf cart charger and 40gal water heater. So it was kind of a rough number. I have a generator 12kw that's on propane and does around 9kw and will run the house...

what would be your thought on this battery load test I have one already in the garage which it acts like a heat on the load and do your process instead of purchasing the light bulbs? https://www.screencast.com/t/ftblxFeiqHh

Got will do thanks again to all for there help this has been a good learning curve.

I really appreciate the information I just a msg back this morning from the guy I purchased it from and he reached out to another guy that responded back and said he put a active balancer on his unit and says it works great now But my guess he has left it wired in all the time.. thanks for...

Unit is around 1 1/2 yr old and worked fine but had a issue and I sent into the factory and has not been un boxed as I changed the unit out for 10k units. Selling for $700.00 would prefer local pickup. I live outside huntsville texas north of houston.

Just took that shot of some of the settings although I think the BMS controls all that not the mppt. Now in most cases I use my solar which is a very slow charging typically no more than 18 amps and that will only be an 1 to 2 hours a time at this time of year otherwise if I want to quickly...

I agree and currently running a space heater on the system and do another discharge then recharge and take a look cell voltages and see if they get up over 3.32 area. I keep thinking I watched a video on a balancer and it would take the high voltage batterys and bring the lower ones up to them...

Unfourtanaly it doesn't communicate with the mppt never has worked and support wasn't any help as they wasn't familiar with the battery so it just reads the voltage. And I always charge to 100% and will normally turn battery off.

I will try that tommorow thanks

have to ask where did you get 2 of them for 1k amazon is 900.00 each same on there site. Thanks

The ones I am using is a straight Cat5 with all switch down and only 1 battery. the inverter on its port is 485 232 and can I do have can and rs485 on the battery seems like I have used can and rs485 but not sure now they told me to set to user mode I was after if others have had to order a...

Understand

So this last test was to drain it down to about 78% took equalizer off recharged and here's the current battery voltage is now if you notice the FCC screen used to say 199.9 amp hour recently it said 180.5 amp hour it drops seems like every time I charge and discharge in a course of 6 to 8...
