Well I must say that JBD's support via Ali-express was actually darn good! They gave me the password (wrong one the first time but hey it happens) to the latest software so I could log in as "production manager" and make changes to any setting in the BMS using the very latest version of the...
No I appreciate it @RV8R, I don't you had no ill intent, actually the opposite! I will be honest I didn't read the 30+ pages of the forum thread to read the whole story. Anyone have a 30 second version? I'm trying to understand how a short circuit (and where) would cause the ANL fuse...
@RV8R
Ok, yep you've scared me sober now. I had used ANL fuses coming out of the packs going to the inverters (most packs right now I have are 16S LFP no parallel). Renogy and Victron is what I based my design, they recommended ANL fuses. But it seems that's not a good idea.
So time to spend a...
@hwy17 So I was looking at T-fuses last night. My goodness they are expensive along with the holders for them. Am I looking in the wrong place? I thought this was supposed to be cheaper alternative to breakers. Right now in my cart on Grainger.com I have 6x 60A Littlefuse Type T fast acting...
So its working now! I actually already had that version of the software but it was displaying a garbled mess. I decided to plug it into the RS485 next to the CAN like you mentioned above and it connected, 99% of readable there were still a funky symbols. But I was able to modify the parameters...
Awesome thank you for the additional info!
@LakeHouse - I agree with almost all of my builds are LFP, but these fell into my lap and I'm not going to waste them. They are properly stored, and evaluated during their life with high end equipment.
Sorry about the drawing - yes they are double...
Thanks @Eugenjbd I will download that version and give it a try. I have so many versions of their software lol. Hopefully this one connects, lots of times I get a garbled mess of ascii. I did order the "official" cable from JBD to connect from the BMS to the computer from Ali-express so it'll be...
Thank you @hwy17! I'm a bit confused at what you are saying. Forgive me but I'm completely new at paralleling BMSs with individual packs. Are you saying I should add either a fuse/breaker on the negative only between the P- of the BMS to the busbar? Each BMS has active balancing built into it so...
Hello bright minds,
First off I apologize for my terrible drawing, its a gift I was never blessed with but it gets the point across. I have 3 batteries that are already in a 13S configuration (they came from Audi Q5 hybrid vehicles) they are in a nice metal enclosure and you just have your two...
Hey folks, I am trying to figure something how here, maybe someone can help. I have the same BMS well its the 100A-200A version. JBD-UP16S010-L-16Sl100A-B-R-C.
I noticed even on your screenshots that the Capcity Config for 80% is set to 3.3V. Though under the Basic Protocol Parameter...
Hello bright minds,
I have a really dumb question, but I figured I would ask just in-case it IS an issue, I don't want to find out when its too late! I'm designing some custom enclosures for some of my battery packs. Is there any issue or safety hazard by mounting a JK BMS sideways? So say you...
@gotbeans First off, thank you for the advice! I appreciate you taking the time to respond with your advice. Since I already own the BMS's I might as well use them that way I can monitor each set of cells from each battery via bluetooth. I already have a beefy busbar and appropriate breakers...
I forgot to mention. I have a custom PCB installed under the plastic cover that connects all the balance wires via PCB and the exit point is a 30P IDC connector. So I can just plug in a 30p IDC cable and I get all my voltages from each of the 13 cells. To go from the IDC cable I used an adapter...
The batteries:
I have 3 Audi Q5 hybrid batteries that are brand new. They are Li-ion (Lithium Coltbalt Magnesium, like your 18650's) chemistry. They are 13S for 48V.
I bought 3 JK BMS's: JK-BD6A17S6P
I want to use these three batteries in parallel. However I am unsure the the safest and best way...
