BJV3 cut off problem

[TrashBoat]

Hello im running a BJV3 with a Dynamite 1650kv motor with the stock Dynamite 120 esc with a Castle cap bank and im using 3s 50c 5000 batteries with a s/b 642 prop and after a minute or so it cuts off to about half power.All solder points look good.Does anyone have any ideas whats wrong?thanks for any help.

Could be the Low Voltage Cutoff built into the ESC. What's it currently set at? You can try lowering it to 3.2V, or possibly even turning it off as a test.

I have been running it at 3.4v but next time I run it I will try it with it off and see what happens.thanks
