Hi!

A few days ago, I have put a BL system into my Aquacraft Reef Racer 2.

Here is the ESC (35 A). http://www.hobbypartz.com/07e-c-seaking-35a.html

And here is the motor(4800 KV). http://www.hobbypartz.com/07e-c-sl-12t-2040-blue.html And I use 3-cell Li-Po 1,300 mAh.

When advancing the throttle to the full, the rpm goes up and the boat wants to go, but within a second, something like "Low-Voltage Cut-off" kicks in, and it slows down the boat.

And then, at the full throttle, the boat does not go fast any more. It goes in the mediup speed at the full throttle. And centainly, the battery is still fully charged.

What causes this? Why at the full throttle, does the boat go fast only for a second, and then somthing like "Low Voltage cut-off" kicks in, slowing down the boat at the full throttle?

This is very disappointing. Can anyone help me, please?

Thank you!

James
