Vatrer 12V 200Ah... amzn.to/3AU3lca (affiliate links)

@AndyMcBlane Год назад

Great video as always, keen to hear what the manufacturer says!

@Vatrer Год назад

Our battery definitely has low temperature protection function. We just updated the internal structure. We will only update the battery without reducing functionality. Our 200ah battery has three temperature sensors, you need to put the three temperature sensors together in ice water at the same time, it will detect it, and then it will stop charging the battery.

@AndyMcBlane Год назад

@@Vatrer If the temperature sensor was disconnected I would like to think the BMS would throw an error / refuse to switch the FETs

@tsp2jxd Год назад

@Power Vatrer - is that how low temp sensors are supposed to work? If the one lead senses low temp, that should be enough to turn off the BMS. Epic fail.

@AndyMcBlane Год назад

@@Vatrer I guess we will wait for Mike to test and get back. I just can’t see a genuine failure case where it (low temp cut off) worked at the factory, but doesn’t work on Mike’s desk if the unit was properly designed and tested.

@jacintobernal7954 Год назад

Hello, thanks for your great information. I bought 2 of 200ah and one stopped charging after 9 months and despite doing everything that Vatrer asked me, it did not comply with its 5-year guarantee and only told me to buy a new one Vatrer is not a responsible company, so if you buy, you know, don't get scammed. In the end, I lost more than $600 because it seemed like a good company, until this happens to you and you realize that it is not. Blessings

I saw that video with Will Prowse, he really hammered the Vatrer. If the manufacturer ever watched his videos, they would have known this ahead of time and built the battery accordingly. Imagine the damage they have to overcome now, with that bad publicity. Personally i’m impressed by the updated build quality and intend to replace my AGM RV battery with it in the future.

Looked like every post with a balance lead and main positive/negative lead wasn't even touching the nylon which explains why it was so tight. Did you happen to check the others?

@explorenaked Год назад

Great review. One thing I saw that could be an issue. The nylon lock nut you referred to from the BMS to the negative post was not fully engaged into the nylon which makes it no better than a standard nut with no lock washer. That's why they torqued it down so much that it dug into the ring terminal. In a rough environment, like an RV, it would eventually come loose.

@cmthumboldt6896 Год назад

I noticed the very same thing. Sharp eyes!

@RolandOfGileadOnYT Год назад

It has some Loctite on it.

@StansE250 Год назад

Even if it has Loctite (not an ideal application, as it introduces Resistance), it could have been EASILY rectified with a low profile Nylok nut 🤷🏻‍♂️

The compressed air test produced a definitive result. It's very nice to see it employed in your tests. Also, thank you very much for this and all your reviews. With a few design revisions, this product looks to be a great option, especially for those looking to integrate combined starting capacity for larger RV diesel power units (eg. parallel a bank of 2-4 200Amp batteries (260 amp BMS +peak for 3-5 seconds) to a Victron lynx distribution block.

@racingtogreen2023 Год назад

low temp cutoff. Nice, if it works. I have two of the powerqueen 200ah look alikes, but no low temp cutoff. Had to be careful and put in a transfer switch and an extension cord feed to either my tool shed's battery, or the house, to keep the mini-split keeping the temp above freezing. I have not been able to get the low temp cutoff to work on the Epever AN series 80amp charge controller using basically the same test.

Have you considered testing the Weise 100Ah? I am not able to do such testing as you do. The company says it has low temp protection (Will showed it did) and a 10 Yr. warranty. However the paperwork says 5 years. They assured me 10. I suggested they be more descriptive and fix the paper work. The paper with the battery doesn't say low temp protection...

@coreybabcock2023 Год назад

Can I use my inverter charger in lithium profile and connect directly to the cells bypass the BMS ?

@brentmodzelewski1689 Год назад

Try putting all temp sensors in ice water, it might average them to make decision. It may also use the temperature plus the charge rate to determine if batteries are safe to charge. It could be more complex than you think

@Vatrer Год назад

Yes, you are right, the 200ah battery is not 100ah, 200ah is more complex, as you will understand after watching our video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tP9Bth37CRY.html

@jamest.5001 Год назад

Hopefully they will fix the BMS deal, yeah low temp cutoff isn't a deal breaker for me either, I keep my stuff inside, and it doesn't get that cold in NC for long anyway, I would still rather get raw cells, I need about 400-600ah 12v bank, and eventually about 2000ah 24v, or 1200ah 48v bank, if I go to 48v, (I really need to do so badly, the number of charge controllers is crazy, and I need more, 2x more, with 2x the pv) It will be a while before my 24v bank needs replaced, 1000ah+ liion, I'm just nervous having all that LI- NMC in the house, if I could replace it with LiFePo about 1000ah I'd take the loss, until I could add more, I will probably buy a few cells per month, or maybe save the money and buy at once , after I find a good reasonable supplier, I'd like to get the BYD BLADE cells, in about a year or so, but these batteries are almost tempting, for the 12v bank anyway!

@dickdyson3100 Год назад

I would buy the 100ah one anyways. More options on voltage when buying 4, 100 Amp BMS is common. 200amp is really scary 😳 for BMS.

@aspendell209 Год назад

The company also claims a 100% efficiency rating between charge and discharge, which isn't nearly possible with LiFePO4 chemistry. That suggests to me that this isn't a reputable company and/or they don't understand their product.

@SuperVstech Год назад

Also note, the bms you printed out is fully populated with fetts, the one in this battery is missing several fetts, so I doubt it could handle 200A discharge for long.

@LithiumSolar Год назад

That is a VERY good point. I wonder if this is actually rated for 200A even though the part number indicates 260A because of those missing FETs.

@docbooth8834 Год назад

Excellent video. Get a breath. I am not a fan of aluminum conductors be they buss bars, cables or straps. With the capacity at 200 amps there is going to be sufficient heat to warm those bars up and expand. Where is the goop, grease, etc. for the connections. With the aluminum conductors swelling and shrinking unless they are chromed there is a problem. Still with chrome there should be a fine layer of goose grease preferably Ronny Red grease. The ny-lock nut is good except for the "one use scenario". We all reuse them but that does not make it right. I never have trusted "one shot parts", even on the first shot. Still, better than a smooth nut or a kick there. I love these lithium cells. After 45 years of babying lead acid banks large enough to run a regular house for weeks or one 125 VDC motor for 72 hours or until it went up in flames, I see lithium batteries as amazing. Still, this battery is a "PLUS" and is rated at 207 AH. 202 AH is just another scratch in the finish. Thanks for the education.

I agree, it is a great battery! They just should not advertise it with a feature it doesn't have. That's my only gripe.

@@LithiumSolar Agreed - I suspect the Technical department, Sales department and the Language Translation departments of these companies very seldom communicate with each other.

How can you say this when we have proof of different BMS’s being used????

@@ericklein5097 If you don't believe me, you can buy our batteries and go back and test the low temperature function yourself. If not, you can return the battery.

Is the battery protected from an EMP?

The nuts are called: "nylocks." The nylon degrades when exposed to heat, and one didn't look like it was fully engaged. If the bolt/screw doesn't protrude through the nylon, the locking action is lost. Fiberglass reinforced strapping tape ... across the BMS heatsink?! Strapping tape is meant for reinforcing packages - not for electronic assemblies! That tape will fail with time when the adhesive deteriorates. And that time will be short when exposed to the heat from the BMS. You'll end up with a sealed plastic case full of loose items rattling around inside. Shoddiness!

You would have a better presentation if you got the info from the co. You said you didn’t have time for before uploading your video. Content is as important as timing, in my opinion.

It's really a great battery for the price but without low temp protection it's a huge failure without having a heated space.

@Vatrer Год назад

Our 200ah battery has three temperature sensors, you need to put the three temperature sensors together in ice water at the same time, it will detect it, and then it will stop charging the battery.You can buy them with confidence or test the function.

@@Vatrer Unless you show proof that the battery can perform a low temp disconnect.... YOU ARE JUST AN ANNOYING SPAMMER. PROVE IT OR GO AWAY!
