I have 20 of them and love them. But the "smart" version has tons of problems, from what I read on the forums. What a cool test battery system. Nice video 😁
thank you!
Nice , I always appreciate your tests . Have a nice day .
thanks for the feedback
Nice video. Great overview. Looking forward to see the next video !
thanks!
Excellent review! This BMS will work very well for a remote lighting project that I just started designing. And, I’m using the same batteries you used..
thanks for the feedback
Good test, entertaining and informative content as always. Thankyou
🤝
very nice video easily to understand and comprehensive tests I will now check your other videos as I am looking for a good BMS😊
JK BMS is what I ended up using
Thank you..bms is a hot topic right now. Nice setup
I was holy cow on the temps till i notice the F 😀 Interesting tests!
Прикольный акцент 😉😀 Отличные ролики, спасибо за информацию 👍
спасибо за отзыв
Great review SolarEngineering. Thanks!
you are welcome, appreciated feedback.
Thanks for the review! From the looks of it, 30A on the 60A BMS will be pretty safe to use, less than 100F after 1 hour is no bad at all.
yeah, 30A looking right for this BMS
@@SolarEngineering Will Prowse tested it at 60a and he seemed to not have any heat issues. Maybe the wire is good quality.
My BMS cutoff high/low voltages are 3.4V and 3V respectively. Can you give me feedback on how can I widen the cutoff voltages?
What is the max discharge current pulse before the bms will shut off?
i have 7 life po4 cell at 310ah///// i also have a 8s daly bms at 24v...can i use the bms on cell or do i have to get a 7s bms unit
I have 3 similar BMS one with bluetooth, work for 1.5 year without problems. However their balancing current way low, you need additional balancer.
thanks for the video , what is the low and high voltage cut off of the daly bms?
2.1V/3.75V
Great video 😊. I want your help . I don't know much about electronics. I purchase a lifepo4 battery pack for my ups 12.8v 18ah. 32700 lifepo4 battery my question is can i charge with this bms with my ups like my lead acid battery was charging earlier
Больше тестов хороших и разных)
стараемся :)
i have the 16S 48V 60A version. It gets very hot when under high load (> 30A) and sometimes shuts down even if output is under 60A. Can you do experiment with putting some heat sinks on it?
I'd upgrade BMS to higher amps rather than install heatsinks.
Good Day! Did you ever test ANT BMS? I just thinking how good or bad they are. I know that there is new version (2021 released) and software have a lot of bugs... What do you think abuut it? I need it for 20S LiFePO4. Maybe in the future will be 24s. not sure.
Hi, I haven't tested ant BMS yet.
@@SolarEngineering got it. Good luck in future test's. Btw, there is also one interesting type of BMS that is based not on MOSFET transistors, but on solenoid relay. They normally have way higher working current. Probably it will be even more interesting than ANT bms. Just idea nothing more. P.s. manufacture : qucc
i bought one of these 1 year ago and it had temperature sensor and it was working
i cant find it anymore
Hello.
There was a problem with this board.
After a short circuit, at first the voltage disappeared completely at the output, then it rose to 4 volts, then to 12.7, on the battery 13.4.
Can you tell me if the board went into protection, or burned out?
What can be done in this situation?
Try to charge pack, this should activate BMS
When you connect isdt battgo how accurate is it? Also, you can try iCharger x8 instead, it’s more accurate, display doesn’t turn off and better balancing. I have both but x8 is much better for Diy in my opinion. Great Video!
thanks for the suggestion about iCharger x8, will check it. Honestly, I haven't checked the accuracy of my meter (just relied on positive feedback about this meter).
Добрый день!
Спасибо за обзор!
Есть ли результаты тестов в виде таблицы?
приветствую, таблицу не делал.
@@SolarEngineering ok. thnx
Does mosfets touch both plates or only the bottom plate?
I think both plates, cause 2 sides were equally hot during the test.
Спасибо за видео и тесты. +47 на старте теста заряда, жарковат то у Вас.
У Вас есть возможность проверить работу балансировки? В этом "Why DALY BMS' are so popular? Exactly, I don't know either." видео со смарт бмс daly пользователь "Off-Grid Garage" утверждает что балансировка не работает когда на одной ячейке напряжение выше установленного порога и балансировка работает только во время заряда. Может это особенность именно смарт бмс или балансировка просто не отображается в программе, при определенных условиях.
Хотя моя такая же как у Вас в daly 4s 12v 60A заряд отключает и напряжение медленно но все же снижается с 3.75 до 3.5 и заряд опять подключается, но мне нечем проверить работает ли балансир на 30ма или нет, когда бмс включила защиту от перезаряда.
May i ask, how to wake up bms of the same model, thank you
usually applying charge will wake up BMS
@@SolarEngineering Thank you
whats the point 30amp bms running 60 amps through it?
didn't get it, do you mean 30amps of charging current?
Be the first, Can you do' a review video on multiple BMS for beginners, I can't find a video bms comparison
Split bms,BT UART bms, BT RS485 bms,Active equalizer balancer bms,Continous bms,SOC bms
I bought alixpress, how many more do they make ?
How big is it? What are its dimensions?
in mm:
LxWxD : 80x61x16
Hi Bro, good evening, can four of those batteries rum a fridge, 24/7
Hi, if you are referring to 25Ah cells (small cells in the video), the capacity of these cells is 320Wh. Fridge (mid-size) takes about 900Wh a day, so you could run fridge for about 8 hours.
@@SolarEngineering Thanks very much, thinking about getting some
6:08 '560 Chinese Ah' 😂😂😂😂😂
So it appears that 60 Chinese Amps is equal to 30 SI metric Amps.
I have one.
HVC failure after 3 months.
Almost killed my pack!
piece of something, right? :)
Nice label lol, 560 Chinese AH 🤣🤣🤣
😀Chinese Ah is a new unit of electric charge, about 30% higher than the entire world Ah
@@SolarEngineering We need a chart to convert chinese measurements to SI metric.
230F is 110C. that's hot. lol. As with most chinesium grade BMSes, take their ratings and divide by half for safety. That would mean 30A discharge and 15A charge for this BMS and It would probably be ok. 10AWG cable is rated for 30A anyway, not 60A.
yeah, true
I think that unless it is specifically stated, the ratings should be read as impulse ratings, not continuous, so yes pretty much 30A/15A as a maximum, maybe less?
ТСенк ю вери мач )
You forgot the most important part: how to connect the BMS to the batteries.
You are very wrong about 10awg silver-coated copper silicon wire power ratings, If you do some research into EVs you will see 10awg HTSSCW like this is rated to 80-120amps, as it is hi-tempter wire, even Tesla uses 10awg SW at 80a in all their cars for the heat pump matrix etc, Also If you look inside any EV controller like Savcon, Kelly Sabvgton, Fardriver, ASI, etc or motors like from QS they all use 8awg SCSCW in their 200 and 250a amp controllers.
There is a very big difference between normal copper strand wire vs Hi temp silver-coated copper silicon wire which has 1600 strands of very fine silver-coated copper wire on 8awg, please learn about the ripple effect on this type of wire.
I bought three of these same BMS and in my opinion they are junk. They allow the voltage on one or more cells to go way too high if the cells are not matched very closely. I do not recommend them at all and to me they were a complete waste of money and they have been put in the junk pile.
