Xiaomi M365 battery Revival Over Discharge blinking red four times FIX

If you like this video please subscribe ;)

At begining i got blinking red three times short and 1 time long and on output connector was only 1.4V. All you must to do if all connections on battery are OK yust recharge it manualy. You must recharge all 10 group of 18650 cels. Look at video and be very carefully if you don't know what you are doing don't do it alone.

Hi
How did you set the lipro charger?

[frankscalda]

Good morning,
Thank you so much. Thanks to you, it's flashing blue now. But no way to charge (green light) I don't have bad soldering. An idea ?

Hello ive got a problem the BMS blinks 3 times short and 1 time long also ive measured all the pack and they are 3.9-4.0v but on the output cable to the controller only has 3.8v...

When i start reverse in the situation at 2:06 my balancer (imax b6) say reverse polarity and when i wanna start it says connection break … what I can do

Hi i got a bms i put on battery and its blinking red constantly. And the output is like 16v to 17v switching. Do you know whats up with it. It does not take charge from the charger.

[Aizim]

Oh 4 time red light on bms is over discharge battery?

[Locoloco]

One pack don’t load. It’s stay between 00.42-00.44V. Go down and up. What I can do. Should I replace the battery’s ?

[conorbearsbro]

Any idea why one pack will not take a charge the rest are around 3.7 volts

[wolfganghenzinger]

May I ask, you basically charge the battery packs in one way (+/-) and than you just redo all the charging with -/+? Is 4.2V on the charger OK? Shouldnt LiIo 3.6V? THANKS

[stevenharris]

Why do you not charge the last pack as per the others.

[steencd]

Please explain why you are charging the battery connecting the chargers minus to plus, and its plus to minus. Thank you. It doesn‘t make any sense to me.

Hi
I have replaced the bms board and both rails but still have 4.red led lights. The battery pack voltage is 40v but the bms output is only 20 odd volts. Any ideas? I have tried another bms but its the same result.

[stevenharris]

Great instruction and video but still not working. BMS will not go blue any ideas

Hello, thanks for video. Charged battery pack like you show. BMS show solid blue light. But when i turn on scooter i see on lcd one green dot blinking thats mean the battery is discharged. How can i solve this?

[Fiveweezy]

I have almost the same balancer as yours. I get the error "CONNECT ERROR CHECK MAIN PORT" I have done everything you said in the video, any suggestions as to why I get this error?

LiIo Charge
0.2A 3.7V(1S)

Connections look identical to yours.

Have same problem all cells are reading 3.8v but same issue

When battery in scooter

Its not holding charge and not turning on unless charger connected but turns on with error

18v total on output cable

When pressing BMS switch

Blue led few seconds then red flashing lights

4 blinks on my battery BMS when connecting 42V to charge wires; unfortunately it's not taking a charge (charge light is green instead of red). Main battery leads measured 2.8V instead of 40V. Now trying to charge with 42V over main leads to see what happens, it is taking a charge so far...

[meco]

My battery reads 3.53v is that not normal
