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.
@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.
@@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.
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.
Great Review! 1 other thing I saw in video was the nylon nuts. 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? A good rule to follow for nuts is to have a least 1-1/2 threads showing on top of ANY nut.🤘
Nice review! Blows my mind all these batteries, most still do not include simple low temp protection. Especially with all the videos we all do, you would think they would catch on by now :)
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
Yes, you are right, the 200ah battery is not 100ah, 200ah is more complex, as you will understand after watching our video. ruclips.net/video/tP9Bth37CRY/видео.html
@3:34 It doesn't look like the bolt/screw is long enough for the nylon "thread lock" to be engaged properly! (On the negative battery lug bolt.) Or am I seeing that wrong?
The battery was sent to Mike for testing by ourselves. If there is no low temperature protection function, we will not test it for him, and then let you complain about our false propaganda.
@@Vatrer you make people think you are an angry, frustrated company. You should try to be nice to people that want to buy your battery. Instead, you are nasty, condescending, and rude. I will stick with ANY other battery manufacturer before buying from Vatrer. I don't even like saying Vatrer. It's annoying!!!
The companies that use their profit to improve the product, while sill being a low cost, fair quality product, is a company I can get behind,. Continue to buy from, and recommend !
Great to see another video from you. Always enjoy your content. Bummer on that battery not having low-temp charging protection because it looks like a very good product, otherwise.
Will you please check out a new brand battery from O'Cell Tech Lithium. Its a 36v 100AH meant for golf carts. The question is about whether its a lithium battery or LiFiP04. There is a vent on the side of the case to "vent gasses" as stated in the video on the battery. Thank you for your effort in educating us about these batteries.
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!
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.
I puchased 2 of the Vatrer 200AH Plus batteries 3 months ago. I contacted their customer service today about purchasing additional Vatrer 200AH Plus batteries to add into parallel configuration and they informed me that their current version of this battery is not compatible in parallel or series with the ones that I just purchased from them. Seriously?
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.
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.
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.
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.
diesel trucks pull a lot of amps i doubt if theses batteries would last very long . there is one i saw made to do both in a car which can pull 400amps easily plus you need a dc to dc charger and you cannot charge unde 32 F OR 0C remember class 6 to 8 often have 2 # 31 1000 cca or size 3 to 7
They don't allow changing of settings in the app - and that's a good thing honestly. No reason to tinker with settings that could create unsafe operating conditions.
The Chans 300 amp hour battery is the same price and has high and low temperature charging protection and is just as well built plus another hundred amp hours
Per chance there is something in the BMS that is allowing charge at low temperatures because your only charging at a very very low rate. I think you said 1.5Amp, not sure if its a mosnomer or not but i thought you can charge at below zero but at very reduced rates ? Just clutching at straws, thanks for your time.
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.
Cold temp? I can get over it in a hurry. I am sold! But I am preparing to buy one...how do I know if it's the newer (upgrade inside the case) vs older one? Is there a serial number designator or date stamp or ?? to make sure I'm getting the new design?
Can I charge that battery with a 50 amp charger with direct current? Will the bms limit the current of which it accepts when it gets close to full charge and float with the bms ? Or do I need a smart charger?
Great video thank you! I was wondering if you think this could handle a boat AC unit. I currently use a 3000 watt generator and only kick it on for about 15min at a time every hour over night.
I think you might have an older battery. The battery model number on your case has a K at the end and any listing Im seeing isnt showing a K in the model number ...so Im also assuming they are listing their newest battery models....could that be the issue?
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...
I just watched the cold test several more times and I never saw him put all 3 sensors in the ice cold water at the same time. Maybe the manufacturer is correct, all 3 must be used.
@@PeteLeuenberger I peaked inside and it looks like a JBD BMS and possibly EVE cells. No immediate complaints seen. Hoping to have a full review done by the end of next week at the earliest. It's being charged up for the capacity test currently.
@@HomeSysAdmin Thanks a bunch for that early info ! So it looks like to be one of the better built version, not like the one Will Prowse had done a review on. Any further updates will be greatly appreciated.
@@PeteLeuenberger Wooops, didn't even realize I was logged in with the wrong account. And yes, NOT like the one I tore apart that smelled like leaking electrolyte either......
As stated above, cool the entire battery to below freezing and see if it still takes a charge. You would need to leave it sit for a while (like overnight) to ensure the temperature inside the enclosure has reached the same as outside. This is the only way to know.
Do not worry，There's definitely low temperature cut-off protection, and you can also watch Will's video, which has long been proven to have low temperature protection. 200Ah also has it, which is an accidental accident.
I see the spec of 10P allowed, and 4S is allowed... Can 10P be set in series? Meaning what is the largest bank that can be built? It sounds like they can be arranged 10P and you can arrange 4 sets in series for 2000Ah 48V setup of 40 batteries... No?
The booklet doesn't specify; however, I assume it's the "standard" approach per most other companies where you would series connect 4 then each series group be wired in parallel. Total of 40 batteries.
So I pulled the trigger on (2) of these, in 100ah, on CyberMonday. Will’s Review had me (discouraged). I guess due to the negative exposure, they Corrected the key Problems (solder vs. Crimp) before you got your example. I made them Assure me, whatever that’s worth since I won’t be ripping them apart, but I wanted it in Writing in a private email exchange, that they Crimp and no longer solder ! The Nyloks hadn’t become evident til I saw your Review. My decision took A LONG time, and I had whittled a Long list down to Weize and Vatrer, based solely upon economics. Reputable Docan Power came out with one, but No Reviews to date and I seldom feel “lucky” in rolling dice on unknowns. The Vatrer came in with a significantly Lower FDC (final delivered cost) than the Weize, and at the end of the day, my decision was to $ave and use the Savings for an AC Charger. I APPRECIATE You ! 👍🏼😊
Actually they probably wouldn't listen just anybody but they do the big four reviewers if Will gives a bad review they lose sales that hurts hopefully you have enough clout if so they'll fix it if not maybe Will will do a review this is why I wish he hadn't forgot where he started from up hear in Canada we have a lower dollar add 25% and gst add 5% and sky-high shipping which is sometimes higher than the product price so we're stuck with what we can buy from Lows and Rona online free or low shipping costs and all they carry is sealed lead acid battery technology now there is a unit which could be a good Entry level unit but since it has the wrong charging parameters it'll need new batteries yearly it would be a great entry level unit if they'd change from pwm to mppt solar charge controller that could be programed for lithium but as long as the only reviews they get are that it's a great unit because it works when purchased don't care if it dies after the warranty period is over or if it needs new batteries every 9 months to a year don't care if you can only use it every 2 or third day because it has so bad an input wattage
Funny how right after someone does a review of these batteries the price goes up 30 bucks for the 100ah version and no more coupon for the 200 amp on Amazon. Twice now on the 100ah that I've seen. Not sure on the 200.
I didn't realize the Amazon listing was dead. My recommendation for the 12V 200Ah class would be the SOK www.currentconnected.com/product/sok-sk12v206-lifepo4-battery/?ref=lithiumsolar it costs a bit more but it''s sold and serviced by a US company and backed by a 10 year warranty. If you're looking for budget and don't require low-temp charging protection, LiTime is a solid choice (previously known as AmpereTime).
Seems to be a huge disparity in build quality between this battery and the 100 amp hr in other reviews. Anyone know which to expect with their 300amp hr model?
Wow- so much to love, but- no low temp charging protection? I live pretty far North and the boats I'm looking at are even farther North (Nova Scotia)- It's NOT optional for me. I like the 8D form factor with the lower height even. Bummer. Thanks David!
In fact, our models with batteries above 50ah have low temperature protection cut-off function, so you can buy with confidence. This battery may be an accident, we are also looking for the problem.
@@Vatrer Thank you for responding directly & quickly. Glad to know that it was an error rather than a build spec. All other aspects are so well considered- even overbuilt- that it does seem like an oversight or mistake.
I think you should post the manufacture's response to the low temp sensors - it is the right thing to do. You should retest grouping the 3 sensors together. Then post the results.
Such a test is incorrect and can only be tested if it is really in a cold, large environment. Please refer to our video ：ruclips.net/video/tP9Bth37CRY/видео.html
@@LithiumSolar most of us rivers do not travel in cold weather and could care less about low temp shutoff being a necessity. I do thank you for your reviews and teardowns
Would you buy this battery? Do you think the company will be around for warranty replacement? Do you think this one is representative of all the current manufactured ones or did you receive a "special" one?
I really don't know. I highly doubt it's a "special" one sent for review; however, company has not demonstrated adequate knowledge of internal components to my satisfaction.
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.
REVISED: After reading the manufacturer's response, It needs to be retested. Disregard the following: // The deal breaker is mislabeling. Your blog is worth subscribing thumbs up and subscribed.
@@LithiumSolar Agreed - I suspect the Technical department, Sales department and the Language Translation departments of these companies very seldom communicate with each other.
@@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.
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!
Wild, people only buy low temp protection battery's if they need it. Typical,I went for the battery without low temp cut off, I store them in heated storage. Let's face it if your battery's are cutting off because of low temp than that's a problem in itself, when its cold people need their battery's to work. Heated storage is the best solution.
The battery was sent to Mike for testing by ourselves. If there is no low temperature protection function, we will not test it for him, and then let you guys complain about our false propaganda.
Seems some of these companies will cut corners and only make things better if they get caught... not sure if the aluminum buss bars are large enough to carry the ampere... copper is better...
Forse c'è un timer collegato al sensore temperatura. La protezione interviene dopo un tempo lungo, e non dopo qualche minuto. Presumo che potrebbe essere questo il problema. Forse è stato fatto per consentire all'inerzia di evitare repentine e continue disconnessioni. Riprova e attendi almeno 15' min. Ciao

Not adjustable by the consumer, but yes - it is set/configured by the manufacturer and is possible it's not enabled.

@@HomeSysAdmin Thanks a bunch for that early info ! So it looks like to be one of the better built version, not like the one Will Prowse had done a review on. Any further updates will be greatly appreciated.
@@PeteLeuenberger Wooops, didn't even realize I was logged in with the wrong account. And yes, NOT like the one I tore apart that smelled like leaking electrolyte either......
That thing is built solid!
i have 2 of that brand 100 ah i paid extra for low temp cutoff . is there a way to test without breaking them apart?
Sure. Cool the entire battery below the cutoff and quickly see if it accepts a charge current.
As stated above, cool the entire battery to below freezing and see if it still takes a charge. You would need to leave it sit for a while (like overnight) to ensure the temperature inside the enclosure has reached the same as outside. This is the only way to know.
Do not worry，There's definitely low temperature cut-off protection, and you can also watch Will's video, which has long been proven to have low temperature protection. 200Ah also has it, which is an accidental accident.
you should a try overheat protection, most likely that would have stopped it
What you do with these batteries after test
Use them
A good one with serviceable cells
I see the spec of 10P allowed, and 4S is allowed...
Can 10P be set in series?
Meaning what is the largest bank that can be built?
It sounds like they can be arranged 10P and you can arrange 4 sets in series for 2000Ah 48V setup of 40 batteries...
No?
The booklet doesn't specify; however, I assume it's the "standard" approach per most other companies where you would series connect 4 then each series group be wired in parallel. Total of 40 batteries.
So I pulled the trigger on (2) of these, in 100ah, on CyberMonday. Will’s Review had me (discouraged). I guess due to the negative exposure, they Corrected the key Problems (solder vs. Crimp) before you got your example.
I made them Assure me, whatever that’s worth since I won’t be ripping them apart, but I wanted it in Writing in a private email exchange, that they Crimp and no longer solder ! The Nyloks hadn’t become evident til I saw your Review.
My decision took A LONG time, and I had whittled a Long list down to Weize and Vatrer, based solely upon economics. Reputable Docan Power came out with one, but No Reviews to date and I seldom feel “lucky” in rolling dice on unknowns. The Vatrer came in with a significantly Lower FDC (final delivered cost) than the Weize, and at the end of the day, my decision was to $ave and use the Savings for an AC Charger.
I APPRECIATE You ! 👍🏼😊
Actually they probably wouldn't listen just anybody but they do the big four reviewers if Will gives a bad review they lose sales that hurts hopefully you have enough clout if so they'll fix it if not maybe Will will do a review this is why I wish he hadn't forgot where he started from up hear in Canada we have a lower dollar add 25% and gst add 5% and sky-high shipping which is sometimes higher than the product price so we're stuck with what we can buy from Lows and Rona online free or low shipping costs and all they carry is sealed lead acid battery technology now there is a unit which could be a good Entry level unit but since it has the wrong charging parameters it'll need new batteries yearly it would be a great entry level unit if they'd change from pwm to mppt solar charge controller that could be programed for lithium but as long as the only reviews they get are that it's a great unit because it works when purchased don't care if it dies after the warranty period is over or if it needs new batteries every 9 months to a year don't care if you can only use it every 2 or third day because it has so bad an input wattage
What do you do after these after you tear them down?
I don't know yet. I have a big shelf full of them lol.
Is there a chance you can sell it to your Loyal subscribers? 😏 Regards from New Zealand... I Love your work :) Forcing these companies to improve :)
Funny how right after someone does a review of these batteries the price goes up 30 bucks for the 100ah version and no more coupon for the 200 amp on Amazon. Twice now on the 100ah that I've seen. Not sure on the 200.
Do you have a new link or a battery you would recommend since this one?
I didn't realize the Amazon listing was dead. My recommendation for the 12V 200Ah class would be the SOK www.currentconnected.com/product/sok-sk12v206-lifepo4-battery/?ref=lithiumsolar it costs a bit more but it''s sold and serviced by a US company and backed by a 10 year warranty. If you're looking for budget and don't require low-temp charging protection, LiTime is a solid choice (previously known as AmpereTime).
@@LithiumSolar thank you. I watched a ton of videos and yours made sense, thank you
Seems to be a huge disparity in build quality between this battery and the 100 amp hr in other reviews. Anyone know which to expect with their 300amp hr model?
Wow- so much to love, but- no low temp charging protection? I live pretty far North and the boats I'm looking at are even farther North (Nova Scotia)- It's NOT optional for me. I like the 8D form factor with the lower height even. Bummer. Thanks David!
In fact, our models with batteries above 50ah have low temperature protection cut-off function, so you can buy with confidence. This battery may be an accident, we are also looking for the problem.
@@Vatrer Thank you for responding directly & quickly. Glad to know that it was an error rather than a build spec. All other aspects are so well considered- even overbuilt- that it does seem like an oversight or mistake.
@@DCGULL01 Of course, it is impossible that directly falsely advertise our products like this by ourselves.
I think you should post the manufacture's response to the low temp sensors - it is the right thing to do. You should retest grouping the 3 sensors together. Then post the results.
I did, check here ruclips.net/user/postUgkxuQRI3Zamd5nl3bdBNA_Owxc3a6La9Wkl
Such a test is incorrect and can only be tested if it is really in a cold, large environment.
Please refer to our video ：ruclips.net/video/tP9Bth37CRY/видео.html
If you but one of these batteries & it does not have a bms w/bluetooth, how can we monitor soc? Asking for a friend!
This battery does not have bluetooth. There is no way to monitor state of charge without an external device, such as a Victron Smart Shunt.
Can you please review the Vatrer 460 ah battery
I don't think I am going to review any more of their batteries due to questionable quality/quality control.
@@LithiumSolar most of us rivers do not travel in cold weather and could care less about low temp shutoff being a necessity. I do thank you for your reviews and teardowns
Would you buy this battery? Do you think the company will be around for warranty replacement? Do you think this one is representative of all the current manufactured ones or did you receive a "special" one?
I really don't know. I highly doubt it's a "special" one sent for review; however, company has not demonstrated adequate knowledge of internal components to my satisfaction.
See this， ruclips.net/video/tP9Bth37CRY/видео.html
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.
Has anyone done a teardown and test on an Enduro battery, I am curious how they are 25% smaller in size than other similar batteries.
does anyone know what the exact float and absorption charge settings on MPPT controller should be for this battery? And should they be the same?
REVISED: After reading the manufacturer's response, It needs to be retested. Disregard the following: // The deal breaker is mislabeling. Your blog is worth subscribing thumbs up and subscribed.
Please tell me the size of one cell
Anyone got a link thmo these in the UK? Great video.
You can contact the company and ask here, www.vatrerpower.com/pages/contact
Will do in Germany
Nice review.
maybe they can update the firmware of the BMS so it works with low temp protection?
Our batteries definitely have low temperature protection, so you can buy with confidence. then go back and test
does it have an app for bms? for $700.00 it shoud
Looks like a great battery, so long as you won't use it in freezing conditions, at least the price is right.
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.
@@ericklein5097 100Ah battery and 20Ah battery use different BMS, but both have low temperature cutoff
Is the battery protected from an EMP?
No
great job
No low temperature charge cut off.... Sad
Great video! However could have done with some fire🔥 so I'll have deduct a point and can only give you a 9 out of 10
Why would you want to see fire in a battery review?
@@LithiumSolar Will does fire it's all about the fire, sadly not enough fire here 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
These things are starting to become affordable.
taxes
Nice job
It's like being in first place in a race and tripping 10' short of the finish line.
lol
That Nylon Locking Nut isn't even engaged because the stud is too short.
I'm pretty sure they had some kind of thread sealer on the short studs. If you look at the nut I held up, you can see flaky stuff on it.
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!
Wild, people only buy low temp protection battery's if they need it. Typical,I went for the battery without low temp cut off, I store them in heated storage. Let's face it if your battery's are cutting off because of low temp than that's a problem in itself, when its cold people need their battery's to work. Heated storage is the best solution.
The battery was sent to Mike for testing by ourselves. If there is no low temperature protection function, we will not test it for him, and then let you guys complain about our false propaganda.
There we go; the real Power vater coming through
You are so comprehensive
Dam that cheap where I live this cost close to 1000$ even raw cells are expensive .
Wow, really? Where abouts are you (which country)?
It is amazing how quickly you pull your pants back up after you get pantsed....
Nice!
Seems some of these companies will cut corners and only make things better if they get caught... not sure if the aluminum buss bars are large enough to carry the ampere... copper is better...
In your opinion what’s the best home back up battery let’s say one day with the 220v appliances changed with solar
Test the new "big battery" that are 10.5" tall 47.5" wide 1.5" thick 1.76kw 12v.... $899 is a little over priced but nice to hide in camper
Nice soft icecream cone dispensing (ROFL)
I'm not sure I understand the joke??
@@LithiumSolar The silicone blobs
Forse c'è un timer collegato al sensore temperatura. La protezione interviene dopo un tempo lungo, e non dopo qualche minuto.
Presumo che potrebbe essere questo il problema.
Forse è stato fatto per consentire all'inerzia di evitare repentine e continue disconnessioni. Riprova e attendi almeno 15' min.
Ciao
Free battery. nice
