Re: bluetooth BMS?

It sounds like the BMS is working, but the mosfets are turned off. In the APK on your phone, is the lock unlocked or locked? You want it locked to enable the BMS. Well, I can't even connect to the BMS, the connection fail each timeeither via BT or USB, there is no lock/unlock thing. The seller aske...

Re: bluetooth BMS?

I doubt it is broken even if you kept it shorted for weeks. That is why the BMS can turn the MOSFETs off and it will keep them off until you remove the short. Hi again, alright, glad to hear that. An easy way to check would be to measure the Voltage between B+ and C- or P- with a multimeter. That's...

Re: bluetooth BMS?

How do figure that the BMS was shorted exactly? A reason why your phone might not be able to connect to it could be that you have an outdated version that doesn't support the latest Smartphone firmware. Here is the latest version: https://shouji.baidu.com/software/24043119.html Hello, thanks for yo...

Re: CHEAP NEW ORYGINAL CELLS LI-ION 18650

@molten-core Just read the customer responses over the 28 pages of this thread. I'd say it's his waranty. It's going for 4 years, and it seems to be going without a hitch. It's as good as it gets. Already bought 100 cells a few years ago. Will go blindly for 120 soon. As advertised, cells are brand ...
