Need help for batt setup! Urgent!

[superek4]

I used to race with 6s 3300 with neu 1515/3d but the motor broke.

I tried tekin 1550kv it's ran 80degree.

This 2 setup can run 12-13mins.

Today I tested 4274 hobbywing 2000kv motor with both 4s 4200mah@30c n 6s 3300mah@40c batts. Both cut off at 9mins 30sec.

My race is 10mins.

For 4s 4200mah I geared 17/46 about 38mph. Temp of batt 60 degree.

For 6s 3300mah I geared 13/46 about 40mph at 80% EPA. Temp of batt 55 degree.


Esc setting
Forward/brake/reverse
Punch 5
No drag brake
12% neutral
15 % timing
Brake 25%

At 11.25% timing there's clogging.

Both temp are about 70degree on motor.

Both set up are drawing about 330-380 mah per min. Very high

When I was using tekin 1550kv n neu 1350kv motor I was drawing about 220mah per min.

Much lower temp for the batt n motor too.

Problem is hobbywing only make 2000kv motor so what can I do?

My batt sponsorer is trying to help me make a lighter more Mah batt

The 4200mah@30c is from them.

I want to run fast n light n less heat on my batts
