    JBD 6S BMS? (SP10S020)

    Hello, yes I did figure it out and can now use this BMS in a 6S-10S configuration. If you have been sent something 15S I'm guessing you've been sent the larger JBD-SP15S020 which I don't think you can use in anything below 11S, it has a minimum voltage of 35.1v according to the specs.

    JBD 6S BMS? (SP10S020)

    Has anyone ordered the JBD-SP10S020 in a 6S configuration per chance? This BMS can be ordered 6S-10S and I've ordered it in 8S and been able to change it to 10S by unsoldering the solder joins on the balance leads and then specifying the new cell count in the app. I'm now trying to use one of...

    JBD BMS Help

    I have both a BT module and this touch screen connected via UART at the same time with a cable I soldered myself and it works. You can't have both the screen and a connection via BT used simultaneously but why would you do that? When the screen is on the BT doesn't work, but the screen turns...

    AliExpress: Beware OYE Store!

    Did you lodge a dispute through Aliexpress? I've had a few small electronic items arrived broken or not working and I've found the dispute process to be excellent. Also my very first purchase of CALB 100ah cells came from OYE and Aliexpress mid last year, everything was great for me so sorry to...

    LCD display with Overkill BMS

    JBD have a new touch screen LCD that works off the UART port, I've got one and it's not too bad.

    Deligreen 310Ah cells SCAM

    Who charged them at 4.3v? They didn't do that themselves whilst being connected at the correct voltage maximum of 3.65v. Why didn't more of them swell if they were all charged to 4.3v whilst in parallel. The first photo you provided with the two most swollen cells on the left, has the cells in...

    Deligreen 310Ah cells SCAM

    Then how did the two cells get to 4.3v as labeled in the picture? The Overkill BMS would have cut off the charge. I think you need to clearly read some of the previous replies you have received because your last few responses seem to have glossed over the facts and warnings about how this so...

    License fee to use a BMS in a project

    They are probably just being very cautious, don't name your product a DALY product, could you even advertise that it is using a DALY BMS inside? I have no idea over these matters.

    License fee to use a BMS in a project

    This seems pretty easy to decipher to me, only DALY can use their logo.

    $450AUD 100Ah Access LifePo4 On ebay Australia. Any one tried them?

    That BMS almost looks like a JBD (Overkill) but can't be sure from the pics. Assuming it is, I would ask them if it has the capability to have Bluetooth added to use the Xiaoxiang app, even if they won't supply it you could add it yourself. Would be very interested to hear how it goes if you...

    How many layers normally with this style of busbar?

    Don't know if they are copper, they have some scratches and it doesn't look like copper. Those two layers are about 1.5mm thick in total, I have some of those multilayered CALB copper busbars and it's about the same as 3 of those layers. Yeah I won't be running heavy loads either but they...

    Is this pressure indicator normal?

    Hi Is this pressure indicator normal? It's definitely convex and bowing out apart from the cross. Should it be completely concave? Thanks

    How many layers normally with this style of busbar?

    Hi Has anyone else received or seen busbars of the attached photo type and if so, how many layers are there usually? These came with Lishen cells. These feel suspiciously too thin, like they usually come with more layers but someone has seperate them, used new heatshink and doubled or tripled...

    4s bms with LCD screen for trolling motor?

    Have a look at this page, there's a link to an Aliexpress store. I enquired with JBD direct on Alibaba and they didn't list this module but the sales agent knew about it and it was available for purchase when asked. Post in thread 'JBD 150A "Smart" BMS'...

    Can an 8s BMS be used in a 5s or 6s pack?

    Thanks but I don't have any BMS or the cells just yet so hoping to make an informed decision before purchase. Hoping someone here may know.

    Can an 8s BMS be used in a 5s or 6s pack?

    Hi All Can a BMS designed for 24v or 8s cells generally be used for a lower voltage and smaller cell count pack i.e 5s or 6s? JBD BMS's specifically which I'm hoping I can just program for the correct values. I'm awaiting a response from JBD on Alibaba so thought I'd ask here too. Apart from...

    Overkill Solar vs JBD direct purchase

    Hey, Is there anyway to report on what firmware version you have? Don't recall seeing the Bluetooth app list this? Any idea how regularly they have updated the firmware? Thanks

    Using spring washers for M6 studs on soft alloy terminals?

    Hi All I plan to use some spring washers on the M6 terminals for my Lishen cells with threaded holes (using grub screws and nuts, not bolts). I'm very concerned about how easy these terminals are to strip and figure the spring washers will give me a good indication of the when the nuts are...

    Important, use Locking agent for rods!

    How deep are the threads on these? (assuming M6), and are the battery terminals (and therefore the threaded hole) the same for all the sizes of the batteries i.e 100Ah - 280Ah?

    CALB grey batteries are not cheap in comparison, are they worth it?

    Hey all What's everyone opinions on the CALB grey cells? I'm wanting to buy more for a different battery pack and these CALB cells are actually quite expensive (and bulky in size) compared to the blue aluminium cased prismatic cells. Is there any benifit to the CALB cells to justify their...

    Advice for lifepo4 in very hot temperatures.

    Hey all, just an update, I've decided on simply using a small 140L bar fridge to house the batteries in. I know this might not be the most efficient method however it will only be turned on for those extreme temperature days/weeks and even with the fridge off it might help to insulate the...

    CALB grey cell compression casing - these cells don't sit flat together.

    Hi, brand new cells probably only seen 1 maybe 2 cycles. They have been charged, up to 3.60v and have been rested down to 3.49v when I took that pic above.

    CALB grey cell compression casing - these cells don't sit flat together.

    Hey all I know the topic of cell compression has been discussed heaps and I'm looking into how best to do it for my situation, I was most likely going to use hose clamps at the top, bottom and middle of the cells with alloy C channel to locate the hose clamps and keep the cells really flat...

    Advice for lifepo4 in very hot temperatures.

    Digging a hole is unfortunately not feasible, concrete slab. Night time temps could drop into the 20's but also stay into the 30's (Celsius) Hmmm that's not a bad idea, simple to setup but I would need to put holes in my shed. Will keep this idea in mind. Thanks for this, the BMS I will be...

    BMS balance leads safe with secondary device?

    Hey Steve, thanks for your reply but I don't think I conveyed my concern too well. I'm not worried about the current handling of the wire/balance leads themselves more so any conflicts of the devices potentially trying to perform different functions over the battery pack. For example if I have...

    Advice for lifepo4 in very hot temperatures.

    Hey all My CALB 100ah cells are going to be used for a 12v battery backup system where they will spend most of their time on float charge via the grid. As they are for a backup system I don't expect them to actually see much use. Unfortunately they will also be in a very hot shed over an...

    BMS balance leads safe with secondary device?

    Hi All Is there a risk in damaging my BMS by running multiple devices that use balance leads over the same battery pack? Examples might be the BMS and and active balancer or an ISDT charger for one of its functions such as balancing or discharging. Could any of these types of devices...

    Are these new grade A CALB cells?

    Thanks again Yeah I'm currently charging them in 2x seperate 100ah 12v packs using an Isdt charger to just get an idea of the individual cell voltages and internal resistance. So far there's only 1 cell in each pack (so 2 cells out of the 8) that are a little off, but that could also be because...

    Are these new grade A CALB cells?

    Hi all I've recently ordered 8 of these cells from Aliexpress and the terminals look like the attached, brushed and helicoils in the positive terminals. These cells look new otherwise I can't see any signs of wear on the cases. Voltage out of the box seems good but I'm yet to do a balance...
