Does anyone here have any experience or feedback on Shenzhen Mushang Electronics Co? I have been talking to MS Battery and they seem great. I am looking to put in a bigger order and looking for others experience.
I am looking for 120 X 280ah cells and 40 X 120ah cells. Any suggestions on the best place to look?
A little more info. Just received updated quote.
Welded stud on all cells. 120 X 230ah brand new EVE & 40 X 100ah brand new GFB cells.
DDP to my door in Vancouver is 11476 usd

Thank you very much for

Hi Saitor,
Just wondering if you finally pulled the trigger on the Mushang order.
I'm also interested in the 230Ah Eve cells, and would like to know if you are convinced that they're actually brand new. If they are, then they're quite a good bargain at $62, as they appear to have the same specs as the 280Ah some are selling for $120.

The one other customer on here didn't have a positive experience all round.

I ended up going with Nikkie Chen from Dongguan Lightning. I ordered 120 pieces of Rept 280ah and 40 pieces of catl 120ah. I fully paid for my order on May 10th. I am still waiting on the cells to ship. I had used Nikkie in the past and was happy with the product.

I've got the same problem with Blmpow, ordered May 8th and am still waiting, have messaged them through Aliexpress as to the batteries whereabouts and all i get is 'thank you sir' or smiley icons?? Its like dealing with kids.

Had i known when i first ordered batteries from soonbuy in February then cancelled after three months of silence that by August i still wouldn't have anything to show for my money with another supplier i really wouldn't have bothered. Problem is i've bought a ton of ancillary components to make the batteries so feel compelled to stay the course.

Even if they are travelling by ship i cant get my head around the total silence and no one at Blmpow not having a clue when they'll arrive, its rediculous. All i got told when i ordered in May that DPD would contact me when they arrive here in the UK.

Still waiting.

Don't know if it'll make you feel better or not but you can send me some money and it'll make me feel better. :)

Hope that make you smile at least a little.

Reading post like yours make me wary of ordering anything but ones I can buy and have in hand fairly fast (within weeks).

Credit card companies call taking your money and not shipping the product, fraud.
Contact the police and file a report, then contact the credit card company.

But there are time limits... best to know them and act before they run out.

Its about the only reason to ever use a CC...

lets see i have just made a enquiry 6 pcs. lishen to Europe
I predict.......

They will say a sure thing and quote you a price.
After you pay will come the "we don't have these in stock, so we are shipping something other than Lishen".

It happens a lot. The supply of Lishen cells has dried up, so you will likely get something else or obviously used cells.
Bait and switch is alive and well when dealing with China.

hi Ian are you member of the diysolar forum ?
ever buddy over there is very interested in you battery's so my question is
1 are the Lishen 272ah really $ 75.50 usd
2 do you have them in stock. Nobody has them in stock at the moment .
3 what are the transport cost by train to Holland.
or else try to login.
ho yea i think welded posts need to be 2 cm long :).
this is not a priority thing just a question
have a nice day

this is what i can do about it

Just wanted to share my recent price and other experience getting quotes and chatting with some of the suppliers on Alibaba. Of course they all say the same thing, perfect Grade A, brand new cells, fully tested and matched. and they will all include bus bars and fasteners. Some of them add comments like QR codes intact.

Prices are all very close, except for Amy's, who is about $500 more than the average.

Anyway, I'll probably order 16 this week and get them on the way. I have 16 coming but want to have at least 32 for my 48v battery banks on the skybox.

Comments are welcome!

Nice List. If you are buying 16 or 32 280ah cells from China, ... I personally would buy 2 extra cells to deal with possible development of below par cells; maybe one extra if possible for an 8 cell order. That is my take as newbie with two separate 8 cell orders on my belt.

Amy was trying to address some of the concerns here about actual Grade A matched cells. I think she is willing to sell the same thing everyone else has, but the $120 cells are actually grade A from EVE.
Just wondering: ... Does Amy's more expensive Grade A 280ah LifePO4s have straight plane sides without bulging. ??? If so, I would like to see some pictures (as references for possible next buy). My previous 2 sets of 8 x 280 ah EVEs via Amy (1st @ xuba, then her newer set up ...) were IMO: not flat sided. I am still happy with what I got for the costs. I think I was told my first xuba order was grade A when I asked. On my second 8 cell order, the response was "don't worry". Still think I got a good deal, but did have one bad cell I documented , to get a free replacement from xuba on sea freight time suck. I now think ordering an extra cell or two is a good idea. ... I am still wondering who is selling real Grade A 280ah cells? ... that I would expect to have flat plane sides that pack together tightly without those bulges showing some slight air spaces in between some or all cells. I understand, some bulging is kind of normal. ... I also have question the wisdom of compressing these slight (seen some pictures of worse than slight) bulging cells for solar ...when the bus bars are solid, and when charging and discharge amps can shift dimensions of each battery in way that likely stresses the battery terminals. I used sticky tape between my cells of first try, and think that is not a bad idea, but the bus bars might be tight on some cell bulging (could be modified to take a wider span). My Feedback to all the LiFePO4 suppliers is: I wish flexible bus bars were supplied, or that there was a reasonably priced option. ... my two cents ;+)

I'll let you know how flat they are when I receive my 304AH grade A cells from Amy. Certainly the 105AH cells are flat, but the aluminum is thin, and the weight is great, so can't say yet on the bigger cells. The grade B cells from Xuba (purchased from Amy) that I received were not "bulged", but they do have undulating sides. Without substantially increasing the thickness of the aluminum, I'm not sure it is possible for them to be as flat as the smaller cells. They were NOT bulged, but not perfectly flat either. Certainly you can tell the difference in a battery pack under load between the real grade A, and "other" cells. Certainly I think the real grade A cells are worth the price, but certainly understand how others wouldn't think so.
My house is paid for, I'm not inclined to want it replaced.

  • Not overly happy with the terminals. They came with studs attached but the way they've done it restricts the contact area vs the other terminals I seen. See images below. I'd already bought some good studs and nuts from a local supplier.
This is for a campervan install. I've got a 3000W invertor (will have a 3000W induction hob). The fridge, lights, diesel heater and smaller DC loads will be connected straight to the 24V. I could be pulling 140A (unlikely for very long) from the battery and would've preferred the whole terminal to connect to.
As a retired electrician I'd like to say that the contact area you have shown is plenty for those 1/16 x 1" cross section buss bars as long as the connections can be properly torqued. If the post metal is somewhat soft, good conformance will occur when the joint is tightened. If you calculate the surface area on both sides here, it will be a lot more than (near double) the cross section area of the buss bar itself.

One of my concerns is the integrity of the post thread attachment here so they can be torqued enough to overcome contact surface issues. If welded, the welds need to be properly made, strong and not prone to cracking some time in the future. If tapped, the threads need to be full and close fitting. Sloppy fitting threads will strip if torqued reasonably well. Well you could repair with helicoil, but the PITA factor increases exponentially. I would also like to note that in seriously tough industrial applications in aluminum or other softer metals, helicoil inserts are actually factory pre-installed because they reenforce the threads greatly and resist wear and galling from thread tightening.

One important thing I would like to note though is that I have not yet seen any mention (posts) of anyone using Penetrox on connections. I use this stuff on anything I don't solder, including all crimp terminals. We were required to use it on all terminals and buss bar connections in sub stations, although a special type was required for the high voltage works. Other than 120, 240, or 480 AC, it works great in very low voltage too. I've used it to reduce connection heating in connections on large spot welding equipment (very large DC currents at very low voltage) with great success. This stuff does two things. It fills in micro gaps in connections with conductive material. In this regard it works like heat sink compound, only for conducting electricity rather than heat. The second is that it seals the joint from atmospheric contamination like moisture. The object is to reduce the ohmic resistance of the joint to as low as possible.

You do need to be careful though as this stuff is a great electrical conductor and can cause shorts if excessive material gets out of place (especially with high voltage!). Just use barely enough to coat the interface of the joint, and carefully clean all remains off after the joint is tightened. After the joint is assembled and cleaned, now you can use an additional non conductive coating over the top of everything to further protect and seal the joint and keep air and humidity out. Some of the connections we use to do were so picky you had to wear gloves to keep finger prints off of all surfaces as they could cause arc tracking.

according to my math, you can buy 51.2 v at 280ah. for average $1800. Whereas 4 cheap 12.3 v ( 49.2 total v)100ah batteries would cost about $1600. on amazon. That is about a 60% discount. So are there any major costs to put these cells together?

Don't forget the price of a BMS .... do you have the skills and tools you need? Power supply for top balancing.... chemicals like noalox to improve bus bar connections .... a torque wrench with low values to give a solid connection but prevent stripping the threads on the cells .... a case to put them in .... etc, etc. ....
You can still do it cheaper .... and have a better result if you concentrate on doing it right ... and learn a lot along the way.
