Hello everyone,
Thank you in advance for your input...
- I discharged my Dyson Battery too low and so the BMS (I'm assuming has gone in to Low-Voltage-Cutoff Mode)
Following this, I
- Recharged the 18650 Li-ion pack manually using a DC-Power Supply.
- I have recharged to 4.10V per cell, giving a total pack voltage of 24.6V (6x 18650 in series),
- However, the BMS still refuses to allow the pack to charge or discharge via the Vacuum cleaner/adapter - It still doesn't work - red error LED blinking.
I was hoping that raising the pack voltage back above the minimum cut off would have reset the BMS, this doesn't appear to be the case.
- I have also tested the continuity of the fuses on the BMS, they haven't blown.
- I have disconnected the main +ve (top right in photo) terminal to the BMS and reconnected it.
I am wondering if there is any way to reset a BMS such as this... Would disconnecting and reconnecting ALL the of connections to the BMS make a difference?
Other info...
*Black and White wires - Charger +ve,-ve.
*Blue and Brown Wires - "ON" button on Dyson to start/run the vacuum.
Looking forward to some insight and replies... Thank you so much for your help.
