So like you i got an non original bms in my pro 2. It says its version 0122 without that telling me much. Is there any benefits of upgrade? Also my scooter sometimes are acting odd. I charge it to 100% but then when i start it later it might say 60%, 70% or whatever and then slowly climb showing increasing charge state. This is when the charger is not connected. Unsure if its bad cells or bad info from bms, and thats why i wonder about bios upgrade for it.
i have install external battery but problem is when u take a after ride it's start charging and i wonderin if there is some firmware for external battery?
Hey bro. I have. Ble 1.5.8 obviously it won't flash. I've just got a fake dashboard but for some reason downG will not load any information do I need to get a new controller?
you have to find a battery that will talk to your ESC/DRV .. otherwise it throws a 21, which is in fact a level3 error, highest level, which doesn't allow torque and unfortunately also kills the thing real fast it can't bear the world awake without knowing the 2 temperatures and 10 voltages from the battery pack 😂
sure the 3 phase feedbacks are always one of 3 states 0v2 3v3 3v3 3v3 0v2 3v3 3v3 3v3 0v2 you need to build a resistive divider from the 0v and 5v rails going to the motor - and just tie the feedbacks in one of the 3 above states that'll pass the startup test and let the controller go into normal operation
@@Darieee thank you, can i build the resistive divider with 2x 0,55ohm resistors in serial? With 0v rail you mean ground? Are the Phase Feedbacks in the same rail or should i connect to a Phase at the mosfet Side? And how do you manage the spoof for Brake lever and accelerator?✌🏻
you need to do the divider with 1000 Ohms or more in total - with 0.55 you'll short out the entire 5v rail both the brake & accelerator sit at around 0v8 when they're in their resting position same thing - a resisitive divider with the voltages available there - and it should work but again - use ohmslawcalculator online to calculate your values, aim for 1-10mA of current to pass through the entire divider
@@Darieee thank U, i think i first try it with ble75 V10, i heard there are no Errors. Someone told me i can just connect G with C for the motor, can i try this first? Its easier for me, if it works haha
Didn't even know you could flash the bms with scooterhacking, cool stuff.
Nice video ! Could you give details about the wiring on the ble (brake and accell) to get no error on the bench ? Thanks a lot

Can we conect to BMS directly without controler and display ? UART or CAN bus to get batterie information ?

Installed aftermarket bms like this and i get error 22 now? What should i do
What firmware to install to flash?

I have a fake dashboard too with same problem no support on downG, use scooterhacking utility instead always works for me
it's was same for me then u need a ST-Link usb driver for reset all bio
Hi i really want to flash the repo bit my error 21 doesent allow it how can i do it?

Bro how to bulild the spoofer for the Sensors?
Can you please tell me♥️
sure
the 3 phase feedbacks are always one of 3 states
0v2 3v3 3v3
3v3 0v2 3v3
3v3 3v3 0v2

Hi, i installed this bms to xiaomi 1s scooter, scooter runs but not charging and red light is on in a controller board. so what should i do?
is it better to use custom flash for bsm ?
