I just looked at tower. your ESC is a ARRMA MEGA 40A ESC. 1300mAh 20C batteries are not gonna cut it. Those batteries are meant for 1/16 or 1/18 scale vehicles. Get some 1/10 hardcase batteries with at least 30C and at least 3000mAh and you should be set.
The mega esc looks just like the axial AE-5 esc. no LVC adjustment just a jumper to set for either lipo or nimh
