If you only need 100-200Ah of capacity and you don’t have an unlimited budget, $300-600 hurts a lot less than $1500!

The main advantages of the 100 amp hour batteries is current output for smaller systems and flexibility of where you can install them in a confined space like a boat or rv. If you aren't trying to run an air conditioner 200 to 300 amp hours is plenty of most rv and boat applications. With the 100 amp per battery you can still have a 2 or 3kw inventor and run loads like a microwave or induction hot plate. IMO the ideal for small systems is the 200 amp hour 200 amp bms from ampere time. Same current output as the 100 ah batteries with half the interbattery wiring and cheaper than even the budget eg4 server rack.

As an electrical engineer, it is standard procedure to have at least three manufacturers for every major component in your bill of materials. This practice goes on in everything from your TV to your car. An Infamous example I can remember is when GM had a manufacturer sell them a boatload of defective stepper motors for their instrument clusters, and they mixed them in with all the stepper motors from all the other suppliers, next thing you know everyone's gauges are randomly failing prematurely, while the majority go to 300,000 miles without an issue. Another well-known example is Apple not using the same speed SSDs or processors in various devices leading to "identical" devices performing differently on benchmarks. That being said, the important thing here is the company determines the minimum acceptable standard, the minimum acceptable performance, for Apple I'd imagine it's minimum requirements are still better than some fly-by-night Chinese company, even if they're manufactured in a factored across the street from the Apple products.

I bought this battery back when you first reviewed it, still works well. I bought 2 of the Ampere Time and liked them so I bought another 2. Reason I went with 4 12v is that I can reconfigure my set up in any voltage from 12 to 48 volts. If one of the batteries fails as a 12v system I only lose 100ah, for the other voltages it is a bit awkward to make it work but I will not be without any power as if it was a single 48v battery.

I think many of us, myself included, are buying batteries in this price range just to replace some paired 6 volt golfcart batteries in our campers or to get better runtime and lifetime use in running trolling motors on small boats. Just saving weight, compared to a 12 100ah LA battery, can make these worthwhile in many none solar uses. You're focused more on building solar systems, but a lot of people have no desire to do that, and a server rack battery would be useless to them. They just want a superior "drop in" replacement for the old LA technology and the peace of mind that comes with knowing it will last their lifetime if they are middle aged and use the battery in a typical cycling profile. I'm really glad that you are following up with these drop in batteries because there is a huge customer base out here, that aren't building power walls, that also need your input.

I learned a lot working with this, but the battery still works within spec at 99.5% original capacity I liked this so much, The next year, I bought the 400amp version for my folks home, who live off grid. better specs all around (charging/cutoff voltages that better match lead acid) no need for a quarterly drain down, even better relative short term current draw. The first battery showed up and was a dud, failed in a week, it retained capacity but couldn't deliver more than about 20 amps, I returned it for a new one, no issues since.

I like owning 4 100ah batteries instead of one 400ah or two 200ah because I can split up my system if necessary. A young child or old person is probably capable of moving a 100ah LiFePo4 battery if necessary, or if there is a disaster situation and I need to give one or more battery to a loved one I can do that. Or use one as barter and still have some left. I like having my system be modular and separable but still functional

Funny that the thing you liked about SOK was the metal case. I bought 2 after watching your review of them. Put them on a boat and one of the cases rusted badly. SOK sent me a plastic marine case as replacement for free. But, the layout was different and I had to rewrire it to fit the BMS. I like the idea of a cheaper, plastic battery for a boat.

The limiting factor is the 100amp BMS. You cannot use these types of batteries to direct replace the sagging FLA or AGM batteries, as the motor's starter pulls 300amps in a caravan. Dakota DL+ costs 2x as much for their 60amp but can do 1000CCA's, and does not need any modification of the charging system.
@my_channel_44 Жыл бұрын
As I said in another comment, the main system is (and should be) 48v LFPo. Then, charge your 12v LFPo from the inverter with the included charger from Dakota.

I put one of these in my RV last fall - I hear you loud and clear on price and quality - but overall I just needed a single lithium battery to swap out my lead acid that I can fully discharge without damaging it and having it last 24-36 hours running the 12v options in the rig. If I were doing a whole battery bank or a big solar setup I'd choose something different - but for a direct swap in an RV this makes a good low cost option

I have no complaints about Weize customer support. I had two 100Ah (trolling motor) and a 50Ah (fish finder) on my boat. They handled my issue with no headache whatsoever. After about 6 months (well past the Amazon return period)the BMS on the 50Ah kept shutting down and I would get zero volts. I messaged Weize about the issue and they replied within a day. They told me how to reset the BMS. worked fine for a couple of weeks then it failed again. I messaged them again about the issue. They offered the choice of a refund or replacement. I went with a refund. I bought another 100Ah as an upgrade.

The only reason I like these 100Ah units is they are easy to move around when needed. Pretty hard with server rack batteries. I also use them as a portable 12V source when needed. My friends power ran out last summer during a storm so I grabbed my 100Ah CHINS and an inverter so his sump pump could stay running. However, I wish they would use a smaller casing, they don't need to be that large.

Same here! I have a 200 Ah AmpereTime battery and it’s annoyingly heavy. Two 100Ah would’ve been so much easier to move around. The server rack 48v one I have is even worse.

I bought one of these just before this video came out. 300Amp/hr. The output is suppose to be 200amps continuous. Battery shuts down around 98 amps. This one will have to go back. It won't even run the coffee pot without shutting off. Hopefully it isn't a pain to return. Wish I had watch this video before I bought it. Watch the last one on this battery, that is why I bought it.

I understand what you are saying about 100amp batteries for a system. But I and many other people are looking at 100amp batteries to use in their boats for lights, trolling motors and fish finders. So there is still a need for these smaller batteries.

I can tell you my story concerning "Why people buy multiple 12volt 100ah batteries". The fact of the matter is, I'm 47 years old and my primary interest in for RV use. When I finally took the dive into LIFPO batteries, there were two things at play. First, my experience with traditional Lead Acid 12v RV systems. My knowledge was antiquated and to some extent, this lead me down the wrong path. Second, I did a lot of research on LIFPO batteries before I bought mine and I was exposed to lots of Battle Born videos. These were touted as some of the best of the best. And guess what. They were 12v 100ah batteries. This all sort of fell into place with my old-school knowledge. I had a battery box on the tung of my RV where two 34 size Lead Acid batteries would fit. And I put two LIFPO batteries in there. I discovered that the batteries were so much smaller physically, that I could fit a third one in there, and so I did. In my defense, battery tech, solar tech has moved,,,,,,, sort of rapidly from my perspective, since i was first exposed to battleborn batteries. (I bought renogy batts). It's only now that i'm being exposed to the idea of Server Rack Batteries and all in one charger inverter units. Recently, I've been really turned on by the Delta Flow pro. I like it because I can literally strap it into the basement of my RV and plug in the shore power cord. That's it. Done. I can plug my suitcase solar in if I want, but really the 400 watts of solar is just for fun. I'd charge the EcoFlow the same way I charge my battery bank now. By running my generator a couple hours a day. The beauty of the Eco flow is how simple it is. There's literally nothing to do. Basically just install a strap over it in the basement. I watched your video on using a sever rack battery and an EG4. And while it's appealing being both cheaper and more power, it's certainly not easier and I can't remove it and use it for emergency power at my house. So,,,, I'm torn for my next RV. Eco Flow? Or server rack battery? I figure I got two years to figure it out. The set up I have for my current RV works amazing. Though, i probably spent too much and I could have done more with less. Still, It's soooooooo much better than the old Lead Acid system that I'll eat it as experience gained.

Thanks Will for doing this again. I was ready to buy the Weize after your first review, but hesitated. Glad I did! Also it lead to me your teardown video the the Powerurus battery and that impressed me a lot. MUCH better build quality for not much more money over these budget brands like Chins. I now see the Powerurus batteries are now listed first on your list of 12v LiFePO4 batteries. I bought one through your link and it's been working great now. $0.28/Wh, low-temp protection, bluetooth (the Epoch Li-ion app works better than the regular one), 200A BMS. Only thing I don't like is the case is HUGE and is probably a lot of wasted space in there.

I still love your videos , but your focus seems to have changed from small systems to multiple server rack batteries and large all in one systems that can run air conditioners charge electric cars. All of this is way out of my price range. I wish you would do some more videos on how to optimize smaller systems. I built my system from your mobile book The off grid King with a transfer switch you did a review on. Still need videos on how to get the power to the house from the shed. I just want to run freezer and refrigerator. And maybe switch to 24 volts eventually. You have taught me a lot I hope you will still help us small system guys with occasional videos. Thanks

As an owner of 12 100-amp Battle Born batteries; there are many reasons to buy that configuration. Mostly packaging/placement was my concern and need for my RV solar power system install... I've been happy to pay the entry fee for excellent quality and dependability and the peace of mind knowing I could reach out and speak to BB/Dragonfly Energy over the phone if that I did have an issue.
