    Bely 12V 150AH LiFePO4 battery with Bluetooth, low temp cut-off and heating

    @rickst29, I appreciate your feedback and you've made me think about your point regarding the 5°C threshold for charging to begin. I will find out what Bely thinks of this.

    Request: Review factory capacity test results for 2 x 150AH LiFePO4 battery with BT and internal heating

    In the case of my batteries, I've set up heating to switch on at 0°C and switch off at +5°C, and beging charging. You can set the desired thresholds in the BMS' BT App.

    There's no way two of these would fit under the seat.

    Bely 12V 150AH LiFePO4 battery with Bluetooth, low temp cut-off and heating

    Thanks @ChristophL ? I'll try to record as much as I can during the project. I have two of these and they will go at the back, under the bed.

    Bely 12V 150AH LiFePO4 battery with Bluetooth, low temp cut-off and heating

    I tested the low-temp cut-off and charging heating functions and uploaded a short, but long video on YouTube about it.

    How-to: safely test LiFePO4 battery's cold-temp cut-off and self-heating functions?

    So I did 'a' cold temperature test with the battery and put together a short video about it on YouTube. Main notes: when I plugged in the 15A Victron charger the relay(s) in the BMS went open/close several times (you can hear it in the video). After the relays settled in, App showed no current...

    Xiaoxiang BMS app/software update from wnsnty.xyz????

    Question regarding the Dashboard on v21 and v26. My BMS has two temp sensors, one on the cells and then the one incorporated in the JBD BMS. The dashboard shows the temp of the BMS, but I'd like to change it to show the temp of the cells, but haven't found a way to do this. So now Temp-2 is...

    Bely 12V 150AH LiFePO4 battery with Bluetooth, low temp cut-off and heating

    Battery #1 Charged to 158,3Ah. ~15A for the duration of 12h10m yielded 158,3Ah So at least the capacity is as advertised for both batteries. I still need to figure out the optimal parameter settings for my use. I will also try to test if thew low-temp cut-off and internal heating are working...

    Bely 12V 150AH LiFePO4 battery with Bluetooth, low temp cut-off and heating

    Battery #2 disharged to 161,78Ah when the BMS undervoltage protection kicked in and discharging stopped.

    Questions about Xiaoxiang App

    Thanks. The thing is that both batteries connected fine with the v21 and v26 apps, but since this morning all BT apps seem to hang and crash with the other battery, The other battery works fine with all versions I've tested. The only thing that has changed in this particular battery that has...

    Questions about Xiaoxiang App

    Same issue. On Battery 1 all these versions work really slow. On Battery 2 all work well.

    Questions about Xiaoxiang App

    @WingNut - many thanks, I'll try to set these but as we speak, the Xiaoxiang is working randomly. It might ask me 1-10 times the password and when it finally opens, it seems to freeze before it actually crashes when trying to access the Parameters View or anything else. I've tried v21 and v26...

    How-to: safely test LiFePO4 battery's cold-temp cut-off and self-heating functions?

    Doing the capacity test. My testing seems to span several threads (sorry!), like in HERE. I will try to compile main findings HERE.

    Bely 12V 150AH LiFePO4 battery with Bluetooth, low temp cut-off and heating

    Battery #2 Charged. ~15A for the duration of 12h10m yielded 159Ah. After 12h I will start discharging it.
