Bluetooth app for monitoring and control only. Settings are fine left as default .
low temp cut off is not required in my part of the world. Temp sensors work fine otherwise
jbd store is a subset if AliExpress

All good buddy,
ali is a bit like eBay , for China I guess. I’m down under. And sourcing items from China is not much different from the US or Europe in terms of time for delivery.
I Started by communicating with the selected Ali store confirmed price and then payed by a CC with insurance...
No pics , as installed. Think two identical banks of eve 280 ah x4 with the BMS I linked in a standard extra large battery box.
I purchased the lugs at an electrical store and crimped it all myself.
yes it has a temp sensor.
best to google and decide.
just a warning , if your not confident...
It’s the JBD AliExpress shop front as far as I can tell. I was provided the shop front in another thread in this forum.
yes performing very well. I’m not sure why overkill are not selling them. Perhaps overkill re sticking to a single line of BMS which I’d understand . The 150a is possibly much...
Yes Bluetooth dongle included , I also had the PC unit added to my order .
4S Lifepo4 or Lithium Ion Battery smart Bluetooth BMS 12V with 100A or 150A constant current UART communication

I’ve gone for two of the jbd 150a versions. Each Bms on its own 4 s pack.
my inverter is 8kw / 4k continuous, however I don’t this I’ve ever needed to get it much mast 3k. at these levels the 150a Bms units don’t break a sweat. The 100 or so amps out of each unit is take. In its stride while...
Yes, the two connectors between the temp and balance leads. Just like the photo you have put up.
On each connector , middle two goes to the temp probe, the outer two wires are red and black
Currently using the payed apple iOS version .
im travelling with minimal tools for the next two months, possibly a delay in measuring that voltage . I’m keen to measure , however may not respond on that one until May/June .
Yes, those two four pin headers are populated on my 1.5 units with connectors.
two wires, center from memory go to the two temp probes, the two outer wires are terminated red/black.
the third temp probe is the same as yours.
I really appreciate the detail and photo provided.
yes, agree . I can’t work out their purpose. Perhaps additional balance current in an upcoming version.
another difference I’ve spotted . My 1.5 has two additional temp probes next to where your balance cable plugs in. And between your temp...
Thanx for that. Would be a nice addition to a battery. I think Bluetooth provides more data and control . The option is good to have.
mounting may require some kind of film or cover to recess the buttons .
Great work finding this .
any other changes on the 1.7 ?
my 1.5 was supplied with...
Great post. Straight to the pool room for that one....
a few questions;
Does the LCD screen include some toggle buttons for control ?
Can the backlight be turned off ?
Is it reasonably easy to mount the LCD with a dremel or similar?
