The item bonded the ABS sticks very well. However, it did not bond the plastic guard of my drone. It is probably not ABS. I have another general purpose TAMIYA. It did not work either. I need to figure out the type material it has.
It worked for a week then the circuit started to cut the voltage at 3.85 V when charging. I detached and attached the circuit again, it was normal for only one charge. Then the same early voltage cutting happed again. I checked the batteries they were ok. I installed the old BMS from the old battery pack, it is working quite well. I believe I charged and discharged the battery about 10 times with the old one, still working well.
