Thinking if we derated this BMS to 50 to 70 amps (perhaps more with good airflow). It is still a very good BMS for the price. If I needed 100 to 140 Amps I would just use two in Parallel Probably use 3 in parallel if i needed 200 amps. I also considered breaking the battery pack into smaller modules with each module using one of these BMS's
I'm curious how well it would have held up when adding your own heatsink and fan to it. It held up much longer than I would have expected without those.
Good day i have 4s 100a bms but my battery have a total of 54amps of discharge current my question is what is the wire gauge that connect the battery to the bms thanks
Curious if it would hold up at 50 amps. Probably wouldn't fail so quickly, but if it heats up close to 150F, then it is still going to likely die with constant use at that rating. Always nice to see some of the cheaper ones tested.
Blake, thanks for your wisdom. But some people prefer watching murder scene. Imagine the guy drove the device to 300f and he was cool ! The other alternative, best suited, would have been a Mossburg 500 /12GA aimed at the device and…… I have deleted my subscription…..
hi I connected this bms with 4 6500mhA (approximately) life4po 3.2V batteries but I can't recharge the batteries, I managed to do it using 14.1volts (using a 3A voltage regulator) but it took me 4 hours! !! I tried with a more powerful power supply but it burned out! Too bad it was new! I'm going crazy because I needed to charge them with 12 volts... what a disappointment, so much wasted money I made before and it cost me less if I bought a motorcycle battery!!!
@@SolarEngineering whys that? After having 2 dalys stop working and leaving me high and dry who do we trust to provide a quality product? Having multiple bms just makes it easy to replace for when that happens and provides economic redundancy.
@@guysgt5003 "...we used a controlled environment and put 100 A through that BMS for three hours solid. Bursts of 300a into it and it worked flawlessly..." - any video, I mean, would love to see for myself.
@@SolarEngineering Да вещь не дешевая, для одного раза даже разорительная, когда захотел обжать кабель 25 квадратов( 3 AWG) оббежал 6 автосервисов, и только в одном такие клещи были… даже для сервиса дорого 🤔 но зато и результат очень крут!
Thanks for the test, this helped me a lot and saved me money.
Glad it helped!

Maybe it's going to help. IMO it's better to get a little bit more realistic 100A BMS.

If a board with B-, C- and P- pins, can i connect such as symmetrical, charging and load in parallel together only on C-? BMS hx-4s-f100a bms
Hi prob would worked fine at 100a with a computer fan fitted dont you think? Will it charge at 100a to?
Is it all the A* written bms are max or burst current?

I love the way he says negative so Russian.
thank you my friend )
Проверить с дополнительным радиатором наверное стоило )
How many watts is soldering tool ?
100
Any BMS like a "4,2V Zener diode" / on cell.
4,2V x 100A = 420W heat... / cell.
Pretty good it was able to handle what it did!
I wish it could do it for little bit longer time
Although for 20 bucks I would get 2 and run them in parallel, then at 40 bucks 100 amps shouldn't be a big deal. Thanks for stress testing this one!
I think it's better to get one more reliable and realistic.
This was a very amateur style test and not very fair for the BMS
@@guysgt5003feel free to provide feedback on what steps were done incorrectly that cause BMS overheating and death.

Минус штекера какой провод, чёрный или красный?
красный идет с аккума прямо на инвертер. С аккума - идет в B- на BMS, из BMS P- идет к инвертору.
@@SolarEngineeringя понял так: красный +, черный - ; акум B - , P - заряд.
ах да, забыл что это было separate port BMS.
P - минус для разряда (инвертор)
С - минус для заряда (charge controller)
NICE BMS

I'm glad you have the courage to solder on camera. There's too many folks afraid of the know-it-alls
Like the "where's your fusing" type folks
haha, actually I forgot to add fuse again 😂
@@SolarEngineering if it were permanent then sure, it's important but for testing why bother thanks for the good content
Получается лайк за просвещение и опыты
Провода моЩные)
@@ivecodaily4x4 спасибо!
I wouldn't trust those to pull more than 10a continuous
at 10A it was not even warm, my guestimate 20-30A
Так дейли выдает 0,13А, тот то 100ку постоянно выдавал) тот норм
That was very interesting experiment! Thanks for that.
you are welcome!
Chinese amps are much smaller than real world ones.
😂
Right 😂😂😂 i bought a 100a bms it dead on 33a 😢😢
Пора купить гидравлические пресс клещи для обжима таких толстых кабелей.
да вот все не решусь никак надо ли он мне :)

up to 96S LFP and NMC BMS :th-cam.com/video/ptQDb-Er8nc/w-d-xo.html
almost any bms from China you can derate by 50%
I always wonder how it’s possible for that bms to handle 100amp, now I know 🤣
👍
Excellent test - reminds me of a favorite of mine : photoinduction ... (another burn in the carpet - lol)
:) It's my favorite type of tests
Great video, interesting findings
Thanks 👍
Great video? You prefer to watch a murder scene? Great findings? Such procedures are done by kids!
