Hi,
I am new to RC. I just bought a toy rc plane with a 3.7V 200Mah LiPo battery. I didnt know about not completely discharging the battery and hence battery was dead in two days.
I then bought a replacement 3.7V 500Mah battery but unfortunately connectors in the two battery are incompatible. I am attaching the photos of the two connectors.
Please help.
