Default Brushless motor lost power after overloading

Hi,

​​​​​​New to forum, got a issue hoping to get some idea of whats wrong.

Got myself a preloved HPI king crawler 1/12 scale.

1. Change the motor to a brushless sensorless coolRC motor. 3650 4300KV with 60A ESC.

2. Using a lipo battery 2300mah, 30C.

The crawler after being overload, i. E come to stop after hitting obstacle the motor will lose torque/ power. Vehicle cannot overcome inertia to move. Without load it still react to the transmitter but at low speed and torque, i. E car lifted up to let the wheel run freely.

The vehicle will only go back to normal after powering off and on again.

I am suspecting may need to change to a highet rating battery or see how can better "discharge" the back EMF which i suspect could be the cause.

Anyone with similar experience or have any advice.

Tks in adv.
