Updates: These are new lishen 272Ah cells, not eve 280Ah. I used the barcode under the covers for verification. These cells were resleeved and had the same overpressure valve as the older eve cells, and same dimensions, and same capacity, so I figured they were Eve. But I was incorrect. Lishen are considered better than eve cells on the forum. And yes, lishun pull higher than rated capacity. 281Ah is not uncommon The cells are now $433. I bought mine for $385 + shipping, and I used my receipt as a reference for this video. The cells in the video have the same dimensions as eve cells, but the terminals do look different. The overpressure relief valve actually matches what is on the EVE cell data sheet: www.dcmax.com.tw/LF280(3.2V280Ah).pdf And grade b usually just means scratched, but a lot of times they are used cells that are not matched (especially on aliexpress). And heavily degraded, mismatched IR. I usually assume the worst. New update 1/9/2021: Gasification is a term used in some lithium ion literature, but gas generation is a more proper term.

Hi Will, thanks for the great info. Super batteries! I suggest you get a thread gauge, cutting tap and some conductive grease. Yes drive the stud to the end, and a small torque wrench does not cost the world. 1/4' or 3/8' is all you need. Then torque test on gear you can sacrifice and note breaking point. Using a third of the breaking value to final torque with light conductive grease on everything current can flow. For a permanent installation use a marker for marking all you torqued. Then a quick spray of de-greasing spray followed by a burst of compressed air to dry. Finally a squirt of battery pole protector spray and the installation is going to last and last. Fitting access points where you can leave a meter that records the cut-off voltage is handy to see if a battery is going astray. If you really want to spoil yourself, a flir camera module to your phone would be the cream on the pie. Keep up the good work. Here in Australia they keep dumping panels by the truck load. If I could get batteries that cheap half of the town would no longer need the grid connection.

Great details included in the video. Love all the detail shared. Surprised that the terminals were all fine for 300 amps. Great confidence test for us looking to build our battery from these. At least those with lots of paciance.

I keep watching these videos to find the ultimate 4wd battery for fridge, lights, etc. Your high amperage rating videos are great and all, but i'm all about the constant load over period of times so I'm glad you cover both.

@Nick Sullivan Looking at this setup in his milk crate setup, how long do you think this would last powering a Dometic-type fridge? Would it be adequate to power diesel parking heater and occasional 1800 watt induction platter? I'd likely run off-road lights off traditional dual battery setup with isolator. Just trying to get a ballpark estimate how long this would last off-grid before needing to recharge/if I could get away without needing solar panels out in the desert for about 5 days. Seems pretty capable.

I just ordered these exact same cells X 3, 2 days ago for my sailboat. Feeling better now.

Planning on getting some soon. But now I'll probably have to wait for stock now that you just convinced everyone to buy some.

Maybe they are onto Will's alliexpress account. I have read that depending on your testing equipment, results can be different for the same cells. I ordered assuming 260ah, we will see what I get (still in battery jail in LA). I think managing your expectations when ordering from alliexpress is important.

I've been waiting for you to do this video for quite a while! The 280ah cells have the softest aluminum at the terminals I think I've ever seen threads cut into.

Thanks for the great review. I plan on getting 16 of these cells to build a 48v battery for my RV.

Thanks for the review/test. I ordered 4 of these cells a few weeks ago along with a 200A Daly BMS... probably won’t get them until mid February. If they work out, I’ll probably get more.

The way how things develop right now looks good for my electric sailboat projects in next few years. In year or two I should be able to upgrade my current boat to lithium much cheaper. And my big boat project will need massive battery within ~5 years. Looking forward to that. Keep up the amazing job you’re doing!

In series configuration all the panels should be without any shade to work properly. There could be combined solar and shore chargers available, but haven’t looked those yet...

@@jonathanself1263 Hi. Yeah, it's definitely possible to use your motor as generator but there's a few but's. - There's no any reasonable current coming in under 6 knots of speed - That means, that regneration works properly only with reasonable big boats. My 27 footer isn't big and fast enough. - There's some compromises to be made of the efficiency of propulsion and regeneration, the propeller shape and size is complex issue that I still know too little about. Solar panels are getting better and better all the time. In catamaran there's often plenty of space to put reasonable big array of them. You can check my channel for some info of doing electric conversion to my current boat. The plan for the 15 meter boat is to do fully electric propulsion but with backup generator for cold climates. Also check Sailing Uma's experience of electric propulsion. They're using second hand Oceanvolt system currently. But they also tested a boat with two servoprops a while ago. Very interesting setup.

Make sure to pack a life boat in case it catches on fire. Wouldn't be a good time.

If you get a thread cutting die you can run it onto a stud with slightly damaged threads with very little force and then you can spin the nuts on with your fingers. This process is called chasing the threads, and if you're working with a supplier of high quality tools, they will actually have a type of die called a thread chasing die, like Grainger or McMaster- Care. But you can probably get away with one from Ace Hardware. Lowe's, not sure what's near you. You can also get thread gauges to measure the size of the stud and the number of threads per inch. You can usually figure this out backwards by taking a nut to the hardware store and asking a for help trying to measure the bolt size and threads. So, that used to be easy in ASE, ( coarse threads), NF ( fine cut threads are stronger). Now from overseas you most likely have Metric,and they can be tricky to match, but getting the right tools may prevent you from breaking off a battery stud. Cost of this would be less than $25, something worthwhile to add to your skill set. Happy New Year, one and all. 👍🔨👍

I was glad to read this as I was thinking the same thing. If the stud size is standardized for Lishen and Eve perhaps someone on here that has already done this exercise can post the stud and thread size (like you I am assuming it is metric) and also possibly the depth. Will advised switching to studs instead of the provided bolts but he did not mention the sizes to use. Here finding metric threaded rod is a challenge so I may have to go to long bolts and cut them down.

So far, I ordered 16 of 280ah 3 weeks ago from Shanzen Basen. This will be for a 6kW split phase low frequency Sun Gold Power inverter, and Orion Junior 2 BMS. Thakns Will for posting this video. I was told that I paid for grade A cells. Your capacity test is what I wanted to see. I spent $1725 for 16 of them with shipping and credit card fees.

I placed an order to the US. Got them for $399 per 4 pack. Got 2 sets for a 24v setup and see how they work. Will be my first battery bank I build myself. Had some experience with used BYD, but wasn’t happy with their performance. Good thing they were cheap. Thanks Will for your info, it’s very helpful.

Build worked out fine for me. I have them in a heavy duty plastic box with some advantech subflooring plywood I had leftover just to give some extra support. I put 8 batteries sandwiched together terminals staggered and made 2 24v packs with a thin pvc separator sheets I found on Amazon. Got it tied to a 150A DC breaker and 150A class T fuse and a overkill solar 100A 48v bms. It was time consuming to build and make it work for me in my cabin setup and look neat. I also have this tied to 3 EG4 batteries all in parallel. The EG4 was easier, just plug an play, but for about $2000 and my time I build a battery that is about equal to the $4500 I spent from Signature Solar. I would build again, but I wish there were more options for a prefabricated cabinet that wasn’t so expensive or would take forever to get here from overseas.

Good to see this cells are as advertised as I usually recommend this cells as they seem the best value at the moment. There are some other similar one 272Ah that have rectangular terminals and they have welded aluminium brackets that have build-in studs tho I think those are a bit more expensive it may be a good choice for those with heavier hands :)

Voltage drop against internal resistance is heat P = RI² so just a multimeter and big 1C load is cheap and reliable method.

I bought the 24v 500Amp Daly for my Bus Build. I expect a draw of 200amps max on a 4.5kw inverter maxxed out so I decided to use the headroom for safety. Seeing your 250 amp handle 290 amps was impressive though!

"We have 3000 watts of HEATGUN POWER!!!!" Late at night, I can tell you were tired, but that line deserved the full treatment! All kidding aside, this is excellent. They seem to be very cheap cells for what you get.

i like your vids. finally some good batteries. i just bought 2 packs of then right now.

Another of your great videos. I was hoping you'd critique those 280 Ah cheapies.

Will, in the automotive industry, I found that the best corrosion prevention was had by using never-seize or anti-seize. Of course, we're talking lead acid, but the fact remains that it's conductive and creates a barrier for corrosion. What I'm curios about is that I never tried checking voltage drop across a connection, and wondered if you might entertain the idea of checking a voltage drop dry and one with a copper (or silver, either one, or even both) anti-seize applied to the contact area. IF you happen to do the threads as well, BEWARE that your toque value will decrease compared to clamping force and you can strip the threads much more easily than dry threads! Nobody talks about terminal/connection corrosion, but I would think that it becomes an issue over time, especially with dissimilar metals.

Hey Will, great video and very impressive results! I would make one suggestion though for future consideration. Hook the negative battery cable up to the inverter FIRST instead of the positive. It doesn’t matter on an isolated system like what you show, but out in the wild (like in an RV) with lots of other systems involved, hooking up negative last can and will cause a lot of damage. As somebody who works on RV electrical for a living, I have seen a lot of equipment burned up because somebody unhooked negative on a battery and left positive hooked up. This causes a “wild” power scenario. Car manufacturers say to unhook negative first only because they assume you will strike your wrench on the car frame when unhooking the battery so if you unhook negative first, it won’t spark. Sorry to be long winded, just wanted to pass along a tip from my experiences and years in the industry.
