Depends if you take care of your batteries. They don’t increase lifetime much. They just cut the battery off when it is “reaching it’s limit” of amps or low voltage.
They will also make it easier to charge because you can just plug it straight into your wall and not worry about any settings.
Can you tell me how i can install a bms? I would like to charge the batteries both at one time and not separatly
Btw, does anybody why turnigy 6s lipo 5000mah 20c batteries are cheaper on hobbyking than on any other website? its about half the price on hobbyking, but they say that they cant ship to me due to size or weight
