200a JBD BMS - Full Setup Tutorial

Learning the in's and out's of this battery management system (BMS) took a little research but wasn't rocket science! Hope the video helped!

I'd give you ten thumbs up if I could. I recently ordered one of these BMSs and you filled in the gaps in their documentation wonderfully.

[HiruS]

I don’t have one of these but just wanted to say that your clear and well explained walkthroughs do you credit and I’ve found your ideas useful in the past. Thank you.

[markmeyer]

Greatly appreciate this video Tim🫡 you’re very well spoken, I highly encourage you to continue in your YouTube ventures!

I touched the battery output wires, positive and negative very quickly and the jbd bms went into protection saying "locked MOS" and I can't get it to work anymore. Any suggestion to help me?

[MarkStatkus]

So if you accidentally tap the wrong bin file and bluetooth no longer comes up, is there some recovery on this?

It's important to note that this is only for the JBD 4 cell 200 amp bms. Other cell numbers or amp rating units by JBD are much different. Even the appearance is much different. I don't know too many who use 4 cells to produce 200 amps. 200 amp output would drain the cells rather quickly and the max output would only be 2560 watts. Even if you used 304 ah batteries you only have 3890 whr.
If your batteries are located indoors you don't need to worry about the temp sensor or heating element. The operating range of lifepo4 is so wide that you'll never reach the min or max.
It's not necessary to compress the cells. Uncompressed, average use cycles, these will last 365 years. Unless you have a time machine it's not necessary to compress to make these last longer.
If you're concerned about the heat sink turn the unit the other way around and let the fins be on top. Or better yet put the bms in a box with a fan that runs whenever you are using the batteries.

I put the master disconnect switch on the negative as u did and it cut power to all but one balancer lead as shown on the app by high voltage on one of the cells. This in turn threw off my volatage conformaty on the app. Wondering if u had the same. Also, tried wiring in the on/off switch to a halo LED push button and when i turned on the option in the app, the bms kept turning off/on quickly despite pressing or depressing the halo switch?

I also bought from Docan Power and you are correct, NO INSTRUCTIONS! I have four JBD 200A BMS that I bought from them with my 64 EVE 304Ah cells to be configured in four batteries in 16S 48V that I haven't yet been able to figure out how to install. I have two different styles and neither of mine are the same as yours. One style has four more wires than the other. Any suggestions on where to find the right instructions? Docan Power wasn't any help, they sent me some things in Chinese.

Look up what T-Class fuses are. Absolutely needed for arc flash protection. Lifepo4 is incredibly energy dense and can dump a ton of energy at once.

[TheBigfoot]

At 2:40 you mention the switch plug in and wires, but it's never mentioned again. I guess if you're using the app to control the bms the switch is not needed.
But what if you're in a location with no cell coverage, no wifi, no Bluetooth....like way off grid in remote location?
I wish you responded to questions.
Great video.

Hi,
Have you tested or somehow verified that the low temperature charging cut-off setting really works on this one?
Same question for high temperatures.
Also when I saw the temperature cut-off switch, my first thought was to connect it straight to the switch port, so it turns the whole thing off in case of over-temperature.

[steph]

Thanks for the setup video. I'm struggling with the bms settings. Can you share the settings you used?

[dawidrosinski]

Thank you for your vid. I'm waiting for my bms to arrive. So after that time what's your experience? I must to say that terminal and front plate are definitely to close. I'm understanding that correctly heating point is for negative of the heater and positive go to battery +? And it take charging current to turn the heating before charging? In my bms is two sensors and is it possible to turn on Charging when temp Gonna reach on one sensor? For example one sensors is on the middle of te battery between cells and waiting to reach min. temp to start charging and the second sensor is right under the plate with heater preventing to overheat.

[Simon_Rafferty]

Thanks - I'd not figured out there was a second app needed. The one with the elephant icon, linked from the QR Code on the BMS packaging is frankly useless!

[ketas]

the idea of heater is to heat battery up to above 0c. or maybe around ~30c for best performance. having heater to cut off somewhere 60c is way too hot and unneeded. it's somewhere because bimetal switch is under plate and heater is on top?

a spare roll of kapton tape is also a good idea for using around those terminals, just in case

also there might be issue if balance leads are connected to bms and you switch disconnect switch off

finally, is there a water hose directly over battery and switch?

also, if this was any vehicle, the vibration of any bigger componets becomes an issue as things can vibrate off pcb solder joints or vibrate loose and short out!

[meraguitars]

How or by which condition the heating port works? I have the "older" version WITH heating port. Connected heating films. NO HEATING IS GENERATED at any temperature values settings. However, tested the films connected directly to the battery works ok.
So I wonder when the heating port receives the "-" ?
Contacted the aliexpress official store - replied me with the descrioton of how to connect the heating films))) However, I do know and already connected all as it should and tested all - heating does not work. Then the seller became silent, my questions marked as "read" while no reply made.

[drewhodge]

I'm glad I ordered the older/original version with the longer lugs. I never installed the heat pad to my BMS. Do you know the maximum size heat pad you can connect? I have a select of different sized 12v heat pads. I will need to fit one before the winter. Also worth considering setting up the heat pads at 5 degrees so the cells never get close to 0 degrees.

[ΝτίνηςΙορδάνης]

Does anyone knows the minimum load and minimum charge that can handle? Cose i have a load 0.4ah - 3ah and planing to charge it with 100W solar(so some times 0.02ah charge)So if bms work only above 1ah load its not for small solar . Also if bms allows less than 1ah charge under 0°C to cells?

[alexandervega]

Can I connect two BMS in parallell with two banks of of 16 cells??. If is correct what I need additional to the two BMS. Thanks

[rustylimbo]

Great video, thank you! I just got my cells and was about to start setting them up and realized I didn't understand any of the lingo. Also, tried to find those apps you listed (Android) but can only find the one with the Elephant on it. Suggestions?
