Second pair of rack ears are for the rear rack rails. You will need them for a device that weighs that much. Don't attempt to mount the unit without using them.

Well, that's absolutely what they would before in a typical rack-mount object like a server, ups, or larger network switch. In this case, there are no mounting holes on the back of the case to attach the ears. So... no clue!

thx for the new Video! Nice Battery at first look, but.... 8:15 - 3.752V max cell voltage is def. much too high - i would highly recommend reworking some BMS Settings It could take several hours with the integrated Balancer (max 100mA balancing current) to bring it down under 3.650V or even lower In the App is also visiable, that max-cell #11 istnt even being getting balanced, so it is possible for the cell to sit there, hours after hours at such a stressful high voltage. The cells are unnecessarily tortured The cell undervolt protect. should sit on 2.5V as stated in EVE Cell datasheet That "cell mistreatment" is a absolute bummer The Terminals also look wiredly round (at least on Video) - so the contact surface seems to be quiete small compared to a real flat Terminal? And we havent even talked about the delta cell voltage of 325mV...that is not balanced at all

The damaged terminal screw is an accessory (welded on, but still an accessory). I'd use the cell. I'd cut a slot in the top of the stud and use that to hold the stud from rotating while I tighten the terminal. The terminal will be held in contact with the welded on flat and all will be well. As an alternative to the slot, two opposing sides can be flattened and a small wrench used to hold the stud from rotating. I have a lot of cells with drilled and tapped terminals, and I use a stud with a hex socket. Same idea, using a hex wrench to hold the stud while tightening or loosening the nut.

Looks like a nylock bolt, is it? OK, now I see it is. I greatly prefer the JBD BMS, different people might have different preferences. Like Tesla, VW, BYD, etc. I don't see a need for an active balancer. I think cell quality has a lot to do with that. You can get almost any communication option on a JBD, but you need to order them that way. I am not sure what the screen uses, but it is a communication option as well. Looks well built, although one reviewer on Amazon claimed it is a 15 cell battery (description specifically notes it is a 16 cell battery). I think they did (or still do) offer a 15 cell version, but I wouldn't recommend it. I sent some Vatrer 100ah batteries to Ukraine in 2022, and they are still working fine. I have found that top balancing with JBD can be done with a power supply, albeit slowly. Once balanced they stay that way with the default settings (which is 3.4v to start, only balance while charging). This certainly looks like a battery I would purchase, the price is certainly right.

Love the background! Is that new? Looking forward to seeing how effective the BMS/comms are from this offering. (Turns out no comms, but that's not a deal-breaker.) Aren't those just grub screws that are ran into the welded on terminal? I'm not sure it's really "damaged", per se? That 2.2v low cut-off on the cells is something I would have to fix! I'd bump that up to the normal 2500mah and increase the recovery voltage to 2800mah.
@LithiumSolar5 ай бұрын
Yes, the background and work area is new. I built it for use on my server channel but haven't had time to do much with it yet. I'm not sure how much battery work I'll be doing there as it's difficult carrying 105lb rack batteries up/down stairs. I don't know what's under the welded part but I think the stud and part welded are intended to be one piece - not threaded in to the cell. I'm not sure.

Liking the assembly design and apparent build quality. I'd say the price is fairly cheap, which others have commented about. Prices always vary by nation and region so best to compare prices available to you where you are. BMS settings are not optimal for battery life which is something they should address. On the silicone blobs two things: One is it ensures connector security and two it acts as a 'tattle-tale' to show if someone has messed with it for warranty purposes. There are other ways to do this but silicone and it's dispensing is cheap and easy for manufacturing purposes. The blue loctite residue is an enigma. Does the CS rep simply not know what's going on? Maybe they buy the cells with the studs installed and weren't aware of it? Maybe it's a production line hack for less than perfect threading? No matter what the reason, the disparity is worrying, especially with all the rest of the hardware looking so good.
@OP-fd4lhАй бұрын
I think I know the answer but want to make sure. Would this battery be able for most people to replace the cells at the end of their life cycle or not to? I realize that even 3k cycles is good number of years but I would to just keep using it with new fresh cells if possible.

Whats the difference between 48v and 51.2v batteries? Are they compatible with each other? Is it just marketing?
@LithiumSolar7 күн бұрын
They're all sold under the "48V" category for marketing, but technically the batteries you want contain 16 cells and are 51.2V nominal. The nominal voltage is 3.2V x 16 = 51.2V. Some companies are selling actual 48V batteries, which contain 15 cells (15 x 3.2V = 48V) but don't work as well due to the low voltage near empty.
