Hi all. My 3.7 kwh battery over-discharged in the garaged during storage. Charger won’t charge and connecting battery to the SP140 does nothing as well. Is there anyway to recover the battery or is it time for a new one.
Thank you!
Yah, read the voltage before BMS, what does it say?
Thank you for your reply, I’m assuming the battery has to be opened up to do that?
Hi, open the battery and push the only button on the BMS. I had the same problem and this trick did the job.
That did it Pedroverticalo! Thank you!!

What does this button do, reset? That allows the battery to function again.
In my case yes. Easy fix
