Yes, the battery pack was apparently overdischarged. I may try back-feed charging again through the main discharge lines to get the individual cell voltages higher. I hope by doing so opens up the BMS to accept regular charging.... if it's not yet beyond repair.

Just be careful with back feed charging.. lithium cells are voltage sensitive.. the best way to charge is by individual cells which is the task of the BMS..

unfortunately, the bms will stop charging once the set voltage have been reached even though 1 of the cells need more time to charge.

if that is the case either the BMS is defective or one cell in that pack is defective.

It worked!

Back-feeding the batteries for about 15-20 minutes I guess woke up the BMS. It probably needed the battery capacity to reach a certain minimum percentage. Prior to this, I only charged the batteries up to 4%.

This is the back-feeding setup.... it won't pass OSHA standards, I know.

It's now taking a charge through the charge port; the red LED is now lit on the charger (upper left)

The ESC logic is also seeing that the batteries are being charged.

Now, I'm doing a no-load, 20kph cruise control on the bench to let the batteries drop down to 40%. I want to check if anything is getting warm/hot or if an error message pops up. Then I'll charge it back again to full.

I'm happy it got sorted but I hope I wouldn't have to do this ever again.

thanks...
barangay roads are mga "looban streets" and
not main roads - ok lang naman.
then helmet - lalagyan ng ulam.

It seems yung tires/rims size niya is the same as mio, beat, click etc. similar gas scooters. Puede na sigurong pumunta sa motorcycle tire shops to replace when it worns out..

Anyone using the M365 Pro in Baguio City? Except on very steep roads, how does it fare? Usable pa ba?

I know bawal sa Session Road.

Not enough power to do the steeper roads. Might be better off getting other brands/models with more powerful motors (or dual motors) so you can just ride up the steeper streets.
