Hi,
I agree with Serum. I won't use a mamba 25 on a 1/10 car.
In my past experience I saw 100A on a 1/10 car with a 2S lipo.
I also like to say the Quark 33 is able to be pushed to 50 and has surely more
current capabilities than the mamba one.
Yes I know you want to use an HV setup, and this will keep Amperes lower,
anyway I do not think this is a good choice.
