JK-BMS or Daly BMS?

[kolek]

Prior to the recent problems with the new JK-BMS, it seemed the consensus was that JK-BMS was better than Daly BMS.

Now it's less clear, at least in my mind. I'm leaning toward the JK-BMS.

I have both the Daly 16S 48V 300A BMS and the JK-BMS 200A 2A model to choose from. Battery is EVE DIY 16S2P 48V.

Which is better? I'm leaning toward the JK-BMS.

JK. I got 2 myself. Btw. there is a crapton of similar threads like this if you use the search on top of these pages.
I would never buy a Daly looking at all their issues.

 

[TimE]

JK every time

 

[Hardergamer1]

ANT seem to be the best out of all the BMS.

 

[AshleyL]

Stick with JK.
Owned both Daly and JK, I must say JK is way ahead of Daly.

 

[kolek]

Thanks for the responses guys, very helpful! I'll go with JK.

 

[HighTechLab]

Don't touch Daly. I've seen plenty of horror stories, some including family members.

 

[ScrotusGobbleBottom]

JK all the way. I have 3

 

[timselectric]

JK, of course.

 

[Stable Idiot]

JK. I've replaced 2 Daly's that had lost their smoke.

 

[Quattrohead]

JBD are actually the best, according to me.

 

[Alkaline]

JBD are actually the best, according to me.

And me too

 

[Brett V]

Another vote for JBD/Overkill

 

[Sam Cho TX]

I am part of the JBD gang as well.

The new "problems" are with the inverter-bms or whatever it is. It isn't just a regular BMS

I've got a few JK's, solid. Don't rely on it for SOC, use a Victron smart shunt

Daly would only balance while it was charging. At rest it would cease balance. Made it kinda useless to me. JK BMS SoC in older versions is impossible to set to 100% until one cell reaches the OVP setting, but recent firmware changes have solved this. JK every time.

To be honest im surprised that eveyrbody voted JK bms. I had/have both. Never had any issue with DALY. To be honest i dont see a SINGLE difference in both. Exept that JK bms's internals is exposed to air [i have gray one, not black], have no shell/case, while Daly is enclosed, so im feeling more safe to use daly in my shed where codnensation happens when nights are cold and days gets warm. Oh and my particular daly did not had active balancing. Only passive, but batteries always was balanced well. Had runners when charging, when one cell stoped whole charging process, but that's not critical. loosing few percents of charge tops.
Many people here said 0 arguments why they vote for JK bms. What they have against DALY, beside rumors or other x-files.

It’s not a rumor if you have a Daly doorstop

 

[Daddy Tanuki]

have a total of four DALY's only issue is SOC measurements, and the low current passive balance. FWIW I have actually seen more JK horror stories lately than DALY.

wtih all the horro stories I almost went out and bought a JK to try one out. then started diving into various threads and after a little bit of research, came to the conclusion that its 6 of one 1/2 dozen f the other. this includes JBD as well. ant, electradaus,not so sure aoubt, but the Block Mon system (forgot company name) has issues with install and setup, not to mention cost out the whazoo

It boils down to what is popular so the average idiot can let the smoke out. if the DALY is more popular, more idiots letting the smoke out, if the JK is more popular then more idiots letting the smoke out of them.
