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...
