Hello fellow solar lovers.

I am about to pull the plug on these for my next mobile home:

They look really well build but I guess they have no low temp protection but this is not an issue for me.

Has anyone tried them ?

I've just seen these on AliExpress - seem to be a new brand?

Some say mobile homes use 9.1 kilowatt hours of electricity per square foot, 380 watts for 24 hours per sf.

Seems very high but it's for British Columbia.

Placed an order yesterday for 2 x 12v 200 AH Wulills on AliExpress.

for these https://www.aliexpress.com/item/1005003742224306.html?spm=a2g0o.order_list.0.0.21ef1802wnbl8P

Was $1,416.96 CAD shipped. will report back in 4-6 weeks.

I was not able to get the OP's posted Wulills battery because those cannot be shipped to Canada per supplier's Ebay note.

 

[wildSolar]

I also bought two

 

[wildSolar]

by the way I asked the seller they say that it has low temp protection; I am not goin to take it appart to verify...

 

[Wevenioniq]

I am looking at 2 x 12v @ 400ah. They do look well built. Could you please keep me informed if and when yours arrive. Thank you.

Anybody have their Wulills battery order shipped yet? I got 2 days left before Aliexpress pulls the plug and refunds my order money because it hasn't shipped.

Ordered Feb 25.

Received a UPS tracking number 10 days ago but not yet in shipment . Sent a Aliexpress message to vendor asking when they expect to ship and got this reply "it was normal in transit to your country,it will ship to our Canada Warehouse firstly,then it will be delivered by local UPS logistic,then the tracking information will be upgraded again" Canadian warehouse? interesting.

Another interesting find is from a 12V 200ah buyer from Korea review with pictures of what appears to be a 4S3P configuration of 12 x 60ah cells just based on the pictures and a Wulills rep reply. about 180ah providing 200ah. WTF??? Here I thought/assumed I was buying 4S 200ah cells. Feeling some regret if I am getting this Frankenstein build.

here is the reviews page https://www.aliexpress.com/item/1005003429876258.html?spm=a2g0o.detail.1000013.2.a3c2cdb8Vufky0&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.274681.0&scm_id=1007.13339.274681.0&scm-url=1007.13339.274681.0&pvid=996176ba-f586-486d-aaa2-32c0112dbf22&_t=gps-idcDetailBottomMoreThisSeller,scm-url:1007.13339.274681.0,pvid:996176ba-f586-486d-aaa2-32c0112dbf22,tpp_buckets:668#2846#8108#1977&pdp_ext_f=%7B%22sku_id%22%3A%2212000025746973457%22%2C%22sceneId%22%3A%223339%22%7D&pdp_pi=-1%3B706.18%3B-1%3B-1%40salePrice%3BCAD%3Brecommend-recommend

I think the cells pictured above may actually be 70ah based on Wulills selling 48V 70ah which can only be explained by 16S 70ah cells.
If they are sourcing 70ah cells that would explain the picture above getting anything at/over 200ah in 4S3P 12V.

I am more keen to see if the capacity test shows 200AH........ Did the guy who pulled it apart test it?

If my Korean translation is correct, the battery pack he got is 180Ah. If you observe carefully, you will find that the seller replies "the real capacity is about 200Ah". Can I think so, 180Ah≈200Ah?
I'm just posting my thoughts, nothing else.

I've pulled the trigger and ordered the 12v 400ah as I know it's hard for anyone to find out if these things are crap.
The 180 out of a 200 would make since with 10% loss of efficiency. When I tested my first chins I had to account that my freaking inverter was modified and only 80% efficient..
I'll report back how sad or ecstatic I am, honestly I only need 300 ah, but current batteries are about same price so shooting for stars and hoping to hit the moon.

My off-grid cabin is eagerly awaiting my Feb 25 2022 order. Aliexpress forecasts Expected delivery date: Apr 5, 2022 - Apr 26, 2022. Onsite reviews site 74-90 days deliveries. Going to need them real soon. Snow is melting up North in the mountains.

 

[wildSolar]

Still waiting for my batteries to arrive (nearly 3 months); anyone who received them ? Who tested them ?

Hi, I've also ordered 2x12v 200amp Wulills back in 15 April 22, received notice from Aliexpress, items have been shipped. Expected delivery 24 June 22. Bought these 2 batteries @ AUD $1253. 60 Incl. on a special deal with Free Delivery to Australia. I'm also not expecting these batteries to reach their stated 200 amp capacity , probably a capacity round about 90% . But decision to buy was because at these competitive prices and photos of teardown view, it looks like a reasonable build quality. Will post another review after install and capacity check. Cheers. brooksy65

I have 12 days left before I have the option to open a dispute. Even that takes another several weeks to resolve. I really hope this vendor comes through.

I just ordered the 200AH version on May 7. They said Oh we have stock in Canada, you can have them in 10 - 20 days. So wait 10 days before the automatic refund, I get the notification shipped. Tracking number is not valid for any carrier. Shows that its shipped from China, not Canada. Ask the seller what is going on. They keep saying On its at the port, but needs to go to their warehouse when the tracking number will update and I will still have it within 20 days. so that will be within a week. I doubt this will be accurate, but will get back if it is.

I wondered why these were so much less than others. There is no bluetooth, but, whatever, I figured I could get another BMS if I really wanted.
So I bought two of these for $681.00 cnd for each battery, including shipping. So The price is awesome compared to what else is available right now.

Will report back after do capacity test when I get them. If I do.

The reviews for the seller and the battery were very positive, so not sure what to make of this particular battery. Just wish they would be honest and say where it is, and the real shipping time rather than leading people on.
