Motor max amp 78 can i...

[superek4]

I am using a Neu 1512/2.5d max amp is 78amp, can i use a 4s 2650mah@40C lipo.

It gives me 2.6x40c=106amp compared to my usual 5x30=150amp.

for a 7-10main should be enough as my buggy consumes about 230amp per min based on my 5x30c lipo.

questions

1st. does it affect my amp draw if i use a lower mah batt?

2nd. is the 106 amp enough for race?

thxs!
