I will give that a try. The CC is located behind a bulkhead panel that is a pain to remove , which is why I use the remote. I'll give it a few days and see if it clears on its own before I remove the panel. The CC seems to be working fine, just that pesky red flashing light and error code...

The temp seems to be fine to me, not sure why you think it's low? I have the optional EPEVER temp sensor installed.

I have tried disconnecting/reconnecting the MT50 display, unfortunately no luck.

I have a flashing red warning light on my MT50 remote display and also when I connect via RS485 to my PC a fault listed in the battery parameters on the Solar Station display for "Battery Lo Temp". This seems to be a historical alarm since the current battery temp is 7.5C, which is well above...

While doing some load testing I had my JBD BMS go into Protection: Lock mode. I had toggled Charging Mode Off with a light load and it immediately triggered Protection: Lock and then reset Charge Mode to ON. I was able to release the Lock by shutting off both Discharge and Charge Modes and then...

Even with 2 different batch numbers, my 8 cells seem to cycle extremely well and stay within 15mV cell to cell during charge/discharge. DISCHARGE RATE (18.3A) Cell No Serial No. Mass(kg) StartV EndV Time (h.m) Capacity (Ah) 6 04QCB72714000J 4.156 3.5619 2.784 13h4m 236.88 1...

I received my cells from Dongguan yesterday via Fedex. (8) 230aH cells plus (2) 120A JBD BMS' were packaged well and had no damage. All cells look new with intact bar codes. I could use some help determining if I have 2 separate mfg. lots. I've attached a few screen shots. It looks like 2...

UPDATE: (82 days since order): I've now received a second tracking number from Dongguan Lighting New Technology and it looks like the shipment has been logged at Fedex on 12/1 and is set for delivery tomorrow. According to the Fedex shipping history it's taking the grand tour of the US on it's...

Thanks for the info. I'm not in a rush as this will be a winter project for me but it's nice to know my order is moving along as "typical" so far.

UPDATE: (30 days since order) I received a Fedex Tracking number that shows no shipping info except the ship from location is in California. No dates or any other info. I also asked for the documented cell performance data (cell weight, internal resistance, capacity etc) and was told: Hello...

UPDATE_ I received a reply from Dongguan Lightning New Technology that my order should ship "this week". No other details or tracking info was provided.

UPDATE- I have reviewed previous order threads posted here (very helpful) and also reviewed the offers from many of the listed vendors and have posted payment to Dongguan Lightning New Technology, through Rama Yocoub for my 8 EVE 230aH cells. I was able to process payment through my Credit Card...

I guess they're fine enough for a plastic box. However I think the price is quite unrealistic since these are about 6X what a standard battery box costs, without any additional features. For $120 I would expect some sort of cell compression and perhaps also a cell heating control system?? I was...

Thanks for the feedback. A number of vendors have also contacted me directly and requested a T/T going around the Alibaba Buyers Assurance (direct bank wire) for a discount. I'm thinking that using my CC or Paypal and going through Alibaba is the best security if anything goes wrong. No...

I've collected prices from a number of vendors and wanted to get the groups collective feedback on which deal they felt best about. These were for 8 Grade A Brand New EVE 230Ah cells with bussbars including DDR shipping to the USA. There is a pretty wide price range and a number of these vendors...

I thought the M6 vs M8 stud conversation was within the range of the original thread and since you were part of that conversation, you were ok with it. I apologize if I hijacked your original thread @Horsefly. And based on the feedback, it seems you're M6 stud and a washer should enhance the...

I think he refers to the 10mm post as the same 11.11mm mounting pad in the pic.

Thank you for your feedback. I think the consensus is that the advantages of higher clamping force the M8 stud provides over the M6 stud aren't fully realized due to the torque limitation of the internal cell material. In addition, since my application doesn't require high current, the M6 welded...

When you say the "13mm pad" are you referring to the weld shoulder? l like your bussbar material with no slots, but I think I would prefer drilling a 6mm hole and mating to the flat 10mm pad as intended by the mfg.

This is my first lithium purchase and I'd like to get your feedback on this vendor and their estimate for 8x 230Ah cells. I connected with Rama here on the forum and their website is batteryfinds.com. Any thoughts or things I've missed would be appreciated. Hello Mark, 1- For the battery case...

Just so I understand, you vote for the M6 over the M8? Or either would be fine? I didn't mention my application and this was more of general question regarding stud contact area, but i draw ~25-50A continuously with a 600W inverter and a 30 amp MPPT solar system. Higher spikes to 100A for a few...

trying to evaluate welded studs M6, M8, and threaded holes. I realize the M8 would have the better clamping force. Any thoughts on whether the smaller M6 stud would actually have larger surface area for buss bar to lug contact over the larger M8 stud? Is the stud base the same size on both M6...

I'll be using 230ah cells which are thinner at 54mm (2.12 in.) I thought most 280Ah cells are 72mm no? Dimensions(L*W*H): 174*72*203mm. That would make an 8 cell row of your 280ah's stacked horizontally 23" long and too big for the box. I was thinking about 2 separate 4S 12v batteries, then...

Thanks for the link stepandwolf. I'm trying to fit this into a battery box in my RV which is 22L X 11W X 11H. I found these on Aliexpress, but shipping looks pretty unreasonable. https://www.aliexpress.com/item/1005002448629263.html?spm=a2g0o.detail.1000023.4.5ac279f2Zir5uW

Thanks for the link info. I was hoping to fit all 8 of my 230Ah cells into a single box, or at least find 2 smaller boxes that will fit 4 230's in each.... at a reasonable price.

Any links to the battery box???

Does the Tracer SCC in Lithium Mode cutoff charging separately (at different temps) from discharging? I see they have 2 different cutoff setpoints in the Device Parameters menu.
