I just want to make sure that any parameters we enter for charging are going to play well with your charger. If you have a multimeter, please measure the open circuit voltage, that is, the voltage with the charger turned on but with nothing connected to the output. Hopefully the charger turns on without a load. Most lithium chargers do.

I was mistaken regarding the new temperature probe. It did come with one - it was already plugged into the BMS, but I don't think it is long enough to work.

I also recreated the BMS instructions into .pdf files if anyone wants them...

I got the bulkhead completed and mounted the new BMS and the original 12V reducer. I traced the old temp sensor wire and the new temp sensor IS long enough to reach where the old sensor was located so I replaced that.

I still need to get the info from the charger, but I think I'm ready to start hooking up all the wires?

And any idea what this glue is for the Bluetooth receiver? They also used it to hold the connectors in place. Is it a special type of glue?

Looks like silicone Sealer to me. Is it flexible?

I got the bulkhead completed and the new BMS installed along with the new temp sensor and Bluetooth receiver.

I tried powering up the battery using the Bluetooth receiver button (like the instructions said), but nothing happened.

I hooked the battery up to the charger to power up the battery and the exact same thing happened like before:
1. I plug in the charger
2. The battery turns on
3. The in-dash volt meter shows 86V like it's charging
4. The charger fan does NOT turn on
5. The charger does not charge (battery stays at 70%)
6. As soon as I disconnected the charger the battery shut off
7. The SmartBMS app does not see, or connect, to the battery

At this point if it were me I would check the voltage of each cell (you can do this from the bms connectors)

I tried doing what the BMS instructions said - "measure the voltage between each two adjacent metal terminals on the back of the plug. LiFePO4 battery should be between 2.5 ~ 3.6V."

I was only getting about 0.45V on some, 0.55V on some, etc., but nothing close to 2.5 volts...
