Because both of these do not have overcurrent protection, they will run large loads till they melt. Be sure to use a fuse if you want to use either of these batteries! Very dangerous. Also, these new 280Ah cells should pull 310Ah when new.
@@WillProwse awesome! i was hoping you would review the eco worthy! i didn't see you mention it, but i think the BMS used on the eco-worthy is a JBD. i wonder if it's possible to change the over current protection limit via bluetooth with the overkill solar app? also, you didn't test the high temp cutoff, do either have it? would the high temp cutoff stop the battery eventually from overheating from overcurrent discharge?
Thank you, Will. Although my two Wattcycle 12V300ahmini batteries haven't had any problems, Wattcycle took the initiative to refund me $100 to my card yesterday. This really surprised me. Thank you, and thank you to Wattcycle, this responsible company. You will surely become even greater!
Can you please discuss what fuses could be appropriate. I have two of those running in parallel and attached to a solar array with maximum input of 50 v and max watt product ion of 800 W@@WillProwse
I gained a lot of respect for Wattcycle that within 24 hours of your video they emailed their customers, owned that they are going to rebadge the 300 mini as 280 moving forward, offered a $50 code for buying new “280s” and crediting existing customers $50. Like…. In 2025 there aren’t many companies that would do that in 24 hours based on a review. So bravo to them. Much respect.
Yes, the same thing happened to me. Even though my two Wattcycle 12V300ahmini batteries haven't had any issues, Wattcycle proactively refunded me $100 to my card yesterday. It was really a pleasant surprise. I'm grateful to Wattcycle, this responsible company. Wattcycle is bound to become even greater.
"aren’t many companies that would do that in 24 hours based on a review" How long should they take? With a lack of surge protection 50 dollars is an insult and they should be all replaced.
Wattcycle sent out an email correcting themselves about the 300AH "mis-label" and updated their website as well. Im 100% sure it was because of your video.
Pretty awesome that they’re receptive to criticism and the community. Feel like most companies wouldn’t give a damn about what “some UA-camr” is saying.
I have been using an ecoworthy setup for over an year with zero issues .. but its only in my truck bed camper - 100watt solar panel (ecoworthy), dc to dc solar charge controller (ecoworthy) and 100ah lifpo4 battery with bms. Thank you very much for testing this battery to show its quality and vulnerabilities.
I bought 4 of these back on BFCM and can confirm the $50 _REFUND_ per battery. Full respect to Wattcycle. Given they are legit Eve cells - I’m totally good with the price. I just finished capacity testing mine & all were 305-309AH.
Wow perfect timing!! Building out my own van and planning the electrical right now! Looking at putting in 2*280ah and the mini would be just perfect for the spot I've got in mind :) Thanks a ton for all your work👊🏼
Thanks Again Will for being right on top of it ALL! The responce time from wattcycle confirms You are leading and directing the future of quality, safe products!! Keep up the Great work!!!

Please take a look at the Newtipower 300ah. It's the smallest 300ah that I have ever seen and they claim to use a 250a JBD BMS. Don't know how they managed to shrink cells to fit them in such a small space. Thanks for these teardowns and keeping sellers honest!
Please test a 300ah GenhoalM battery. I got two for $484 US dollars each. They have also Bluetooth and a 200ah bms but my second battery arrived with a clunking sound in the battery case.
I bought the eco worthy battery a week ago. After balancing the cells it appears to work great. Connected it to my RV, replacing the lead acid batteries. The RV built in solar system is weak but charging it full from about a ten percent drop overnight. No complaints so far.
I’d like to see a test of the LiTime 48V 30Ah GC2 Bluetooth Golf Cart Lithium Battery. I think there could be some really cool use cases for such a small 48v battery. Thanks Will.
Will is making these battery companies step up well done Sir I will still be the Wattcycle just because of the cells they using I have that 300 amp hour one so far so good..
Another strange thing about this battery is that they advertise the low temp cut-off is set at 19.4 degrees F. and resume charging at 32 degrees F, doesn't that seem to be a little low?
Since I don't drive my batteries anywhere near their rated current capacity, I would always take the higher cell quality than just a larger heat sink on the BMS. That's just my priority based on application long-term.
It seems like it was just yesterday that finding these things for $1000 was a steal, because shortly before that they were twice as much. Yet I still hear Battleborns are sold for nearly $1K for 100A.
Bravo molto interessanti i tuoi video, mi puoi consigliare una batteria life po4 economica che funziona tutto bene per il mio camper? Non so quale marca scegliere grazie
awesome! i was hoping you would review the eco worthy! i didn't see you mention it, but i think the BMS used on the eco-worthy is a JBD. i wonder if it's possible to change the over current protection limit via bluetooth with the overkill solar app? also, you didn't test the high temp cutoff, do either have it? would the high temp cutoff stop the battery eventually from overheating from overcurrent discharge?
I just received my 12v 280ah Eco Worthy today. The price with the Bluetooth was too hard to resist. It is replacing a conventional deep cycle battery which didn't have over current protection built in either.
After Listening to Will and owning 12-Chins 280 AH Batteries. I added 300 amp fuses to each positive connection at the Battery. Then my SolArk 15 is limited to 100 amp charge from the Grid. If I ever have to use my Kohler 20KW to charge my batteries I will increase my Amp output to 200 amps. Everything is flawless with 19,500 watts of output.
I really hope you would test some of those cranking batteries. Would be great to find a lifepo4 starting battery that is safe to use with smaller outboard motors with stator charging system, but what i see manufacturers are only focused on big outboards with altenators. I find it really silly, because light lifepo starting batteries would make much more sense on smaller boats. There's also some sodium cranking batteries, i guess lanpwr might be first budget brand having those. I know you are more focused on solar, but you are the best battery tester in this world so hope you find some time for those starter batteries.
Echoing the theme I hear from others: I'd only buy a battery that's been reviewed by Will. I don't see any other content remotely as informative or trustworthy. (Thank you, Will!)
I’m wondering if over current protection is necessary in every install. I have a small RV with a single lithium battery. It powers 12v accessories only. Lights, propane heater, fan….that sort of thing. Is over current protection needed?
I have the Ecoworthy 280AH for 1 year. So far, no problems. Mine does not have Bluetooth nor advertise temperature sensors. But the BMS does detect low voltage, high voltage and overload... but I don't know at what AMP. I am always scared to damage the battery, as the solar panels rarely fully charge it in the winter. I am not patient enough to run the generator for 3 hours a day. So, cell equalization might rarely occur. However, at that price for the battery, it is already cheaper that the equivalent Lead-Acid that I usually burn in 1 year because that an RV and I can't put more weight in. So, they often get discharged too much. I have a new ALEOPIX 3500 Watts Pure sine Wave Inverter (Amazon). It is one of the best I ever own and with this battery, it even starts my air compressor and run my electric stapling gun.
to pair this up with the eg4 48v 3000w inverter, just series up 4 batteries to 48 volts? with amazon's deal you would get over 13k watts for under 2k dollars, right?
There's only one problem I ended up buying one of those 300 amp hour mini batteries because of their size. I can't fit a huge battery like that in my project area.
I have eco-worthy ground mount, panels and all in one inverter. All are good quality. They usually have good pricing for the quality product you get. No Chinese branded stuff is perfect, but the eco-worthy stuff works well. My 2 cents.
My disability scooter is fitted with a pair of full size WattCycle 200AH 12v batteries(in series=24v). They are fantastic. I only wish the crap OEM lead acid batteries had lasted another year, so I could have got these awesome minis. I had to modify my scooter to fit the large 200AH ones... but I have a range of nearly 300km vs the original (rather optimistically) claimed 50km. Their customer service is great too.
Just love how you tear into the sh...stuff to see what's hiding in them boxes? Great job on getting Watt Cycles attention. Can't fix it if y'all don't know it broke! 😂
I just bought 2, 280ah Litimes for the same price with cold protection. How about testing the difference between 109 and 144 split cell panels in different types of shading
I'll always pick a battery with better build quality. I'm planning to go off-grid, fully, in the future (3-5 years is my timeframe) so every battery I look at needs to be built with quality in mind. Even if I'm not buying it for whatever home I'm going to live in, the standard shouldn't drop just to cut costs.
I think the logic behind the 850A limit is that it's designed as a last-resort protection, not something you'd ever realistically reach during normal use. From what I've observed, the issue lies with the FETs used in these systems. They are often inexpensive, and their switching times can vary significantly. This mismatch can cause one FET to bear the brunt of the current, leading to failure. In a short-circuit scenario, the 850A protection might disconnect the battery, but by then, there's a good chance the FETs are already damaged or blown
I'd like to see a test on the Eco-Worthy 48v/50ah battery. I have 16 total in groups of 4 going to a Victron power in bus bar. I've had them for 1 year and no problems so far. The case top is screwed on and I've been tempted to take one apart but I don't have the knowledge you have and it makes me nervous to try.
Could you please test the 850 amp and see if it trips within XX seconds. Would love to see how it would work on a boat with bow and stern thrusters that pull 700 amps each for short bursts. Would temp sensors shut if off if it gets to hot? 1400 amps If both thrusters are used at the same time.
You should just go with the Epoch battery for bow thrusters. It can handle 1000amp discharges for a couple seconds, 700 would be handled for way longer. The last thing you want to skimp on for a “critical” bow thruster move is a cheap bms saying “let’s turn off now and cool down…”
@@aussie2uGA yes 12 volts Current system uses 2 lead 8 D batteries. They have about 1500 CC each when new. They are about 3 1/2 year old now so can only get About 30 seconds of spaced out short burst of 3 seconds each. Before I get low voltage warning and GPS/Depth sounder reboot. Time to replace or upgrade with something that could last longer.
Better build quality! Just add a circuit breaker / fuse. Question. Which is a better location for a fuse - positive or negative ? In a RV situation. Thanks
Dear Will, Was considering the Eco- worthy as have had some of their products in the past and have not had any issues thus far. There is another battery that you haven't tested and that is the Kepworth LiFePO4 100 Ah and their 300Ah. The group 31 battery that was purchased had a charger and UBS sockets on the battery. eBay was selling their 300Ah Battery at the holidays for mid $300 dollar range. Are they any good? They say over under current, high and low temp protections but after seeing the two you have just shown is there reason to think Kepworth would be any different? You, through your videos, have encouraged me to venture into solar. You are very good at teaching and showing how to set up a beginner system for somebody not electrically educated. Appreciate you and your videos.😊
Will use to be happy when they pulled the rather capacity but now they have to go way over? He called out the cells in the 300ah battery but not the Eco Worthy? I'm also trying to figure out when you'd pull over the components rating without shorting the battery.
I purchased 2 wattcycle 300 ah minis and feel like i got shafted! What do I need to make my system safe? I'm going to wire in series for 24 volts 60 amp mppt charge controller 4000 watt inverter/charger
Hey Will... could you do a review on a LiFeBlue 200AH Low Temperature battery? I live in a cold area and I'm really thinking about getting these. So are they worth it?
Many thanks for the review Will on the EW. Been looking at these over the last week. Concerns reference the OCP. What would be a suitable size fuse connected to prevent any OCP problems. Cheers
Please test the Elfhub 100Ah 12V batteries! They are $115 on amazon and I own 3 of them that I bought 6 months ago. So far, they have been working great for me and I charge them with both solar or a standard wall powered battery charger.
I bought the Black, non-bluetooth version. I have read in the amazon reviews from people that bought the White version or the Bluetooth variants that they had issues. So far, people that just bought the plain Jan, Black, non-bluetooth, Elfhub battery have had good luck with it.
Great surprise with this battery. I think they have a sister company (DC House) would you be able to get a hold of their DC House 100ah with usb-c and 12v/5a Dc port? I am very curious which cells they use and how they connect the usb/dc ports to its BMS
Hello! Thank you for your amazing videos-I really enjoy watching them, as they’re packed with useful information. If you ever have the time and interest, could you consider making a video sharing your thoughts on low-voltage vs. high-voltage batteries? It would be great to hear about the differences, benefits, pros, and cons from your perspective. I know you use low-voltage batteries, but I’ve noticed high-voltage batteries are becoming more common in the market as well. Thank you in advance!
Any plans to review/test the new ECO-WORTHY 5.12kWh 51.2V Server Rack Battery,3U Size,with Bluetooth & WiFi? They are on sale for $840. Would love to know if they are as good or better than the EG4 LL-S Lithium Battery | 48V 100AH | Server Rack Battery.

Good Morning Will ! Thank You. Have a Great Friday. TAKE CARE..
I am buying Four of these. What size fuse should I use on each?
I would do 250A fuse for each.
@ thank you.
Since I don't drive my batteries anywhere near their rated current capacity, I would always take the higher cell quality than just a larger heat sink on the BMS. That's just my priority based on application long-term.
Golf cart applications can change those thoughts as discharge current is key.
It seems like it was just yesterday that finding these things for $1000 was a steal, because shortly before that they were twice as much. Yet I still hear Battleborns are sold for nearly $1K for 100A.
I wonder if people still buy them? We may find out one day their retail is dead and they stay in business with government contracts.
Could you use 1, or 2 Wattcycle in parallel for a starter battery?
Good question!! I’d like to know this too.
I would still go with Wattcycle because it is more compact and simply fits better in my small camper and boat builds.
Hi Will what do you do with the batteries once you tear them apart?
I would love to see you do a test and tear down of Big Beard Battery.

I'll always pick a battery with better build quality. I'm planning to go off-grid, fully, in the future (3-5 years is my timeframe) so every battery I look at needs to be built with quality in mind.

@@michaelwalls620 Ok, then your inexpensive choices are limited. Ionic makes a nice 1800cca constant current 12V lifepo4 but it's over $800.
Size matters! Kicking ass and taking names. Nice work.
I would like to see this test after balanced.👍⚡︎
Better build quality!
Just add a circuit breaker / fuse.
Question.
Which is a better location for a fuse - positive or negative ?
In a RV situation.
Thanks
I would like to see you test the 100ah 12v redodo
Have you done a review on this battery? XRH 24V 280Ah Self-Heating LiFePO4 Lithium Battery, if not would you be able to?
Dear Will, Was considering the Eco- worthy as have had some of their products in the past and have not had any issues thus far. There is another battery that you haven't tested and that is the Kepworth LiFePO4 100 Ah and their 300Ah. The group 31 battery that was purchased had a charger and UBS sockets on the battery. eBay was selling their 300Ah Battery at the holidays for mid $300 dollar range. Are they any good? They say over under current, high and low temp protections but after seeing the two you have just shown is there reason to think Kepworth would be any different? You, through your videos, have encouraged me to venture into solar. You are very good at teaching and showing how to set up a beginner system for somebody not electrically educated. Appreciate you and your videos.😊
Will use to be happy when they pulled the rather capacity but now they have to go way over? He called out the cells in the 300ah battery but not the Eco Worthy?
I'm also trying to figure out when you'd pull over the components rating without shorting the battery.
Yeah, the cells are getting better. To get 6000 cycles, the average capacity will be 280. So they should pull 310 these days. Technology progresses.
I purchased 2 wattcycle 300 ah minis and feel like i got shafted! What do I need to make my system safe? I'm going to wire in series for 24 volts 60 amp mppt charge controller 4000 watt inverter/charger
Think you could suss out the Mobi 12V 135AH Lithium Iron Phosphate Battery LiFePO4 Deep Cycle?
Did you confirm they were using 280 Battery?
Have you reviewed the vterun battery yet
I bought two of ecoworthy
Can you test the Docan 300ah? They are $410 on their website, ships from the US.. thank you, as always good info!
How much battery would someone need to run a window A/C for 24 hours in the middle of the summer heat ?
Sunsynk 2Kw version,
Epever 3600 PowerStation.
Thoughts appreciated
Hello from BC Canada. Have you done any tests on the Lisuateli?
I would get the Ecoworthy over the watts battery. I can easily, add a fuse for over current protection.
Hey Will... could you do a review on a LiFeBlue 200AH Low Temperature battery? I live in a cold area and I'm really thinking about getting these. So are they worth it?
Many thanks for the review Will on the EW. Been looking at these over the last week. Concerns reference the OCP. What would be a suitable size fuse connected to prevent any OCP problems. Cheers
Please test the Elfhub 100Ah 12V batteries! They are $115 on amazon and I own 3 of them that I bought 6 months ago. So far, they have been working great for me and I charge them with both solar or a standard wall powered battery charger.
I bought the Black, non-bluetooth version. I have read in the amazon reviews from people that bought the White version or the Bluetooth variants that they had issues. So far, people that just bought the plain Jan, Black, non-bluetooth, Elfhub battery have had good luck with it.
Great surprise with this battery. I think they have a sister company (DC House) would you be able to get a hold of their DC House 100ah with usb-c and 12v/5a Dc port? I am very curious which cells they use and how they connect the usb/dc ports to its BMS
I'm looking at a kepworth battery on Amazon, here in the UK. Would love to hear your opinion on one of these Will
Can we put 4 in parallel for 48VOLT
Perhaps off topic but would love review of the G3 walrus
Hello! Thank you for your amazing videos-I really enjoy watching them, as they’re packed with useful information.
If you ever have the time and interest, could you consider making a video sharing your thoughts on low-voltage vs. high-voltage batteries? It would be great to hear about the differences, benefits, pros, and cons from your perspective. I know you use low-voltage batteries, but I’ve noticed high-voltage batteries are becoming more common in the market as well. Thank you in advance!
How about testing this battery? Very cheap. Humsienk. Only $140 on Amazon
What's better ?
2 x 12.8v 280A
Or one server rack 100A battery ?
@4:46 "We're going to test that!" (I hope) re: Wattcycle changing their overcurrent protection.
Any plans to review/test the new ECO-WORTHY 5.12kWh 51.2V Server Rack Battery,3U Size,with Bluetooth & WiFi? They are on sale for $840. Would love to know if they are as good or better than the EG4 LL-S Lithium Battery | 48V 100AH | Server Rack Battery.
