Expert Advise Required - Swamp Boat Refit
Good Morning Shipmates
Took my newly aquired swamp boat (second user) for a test yesterday - unfortunately it did not go well so some advise needed.
The problem - if chugging along at half power things are great but the boat is a little slow - so I increase the throttle and affter a couple of seconds the motor cuts out :-( . This is easily reset by just giving it a little kick astern. On trying againg exactly the same thing happens everytime.
Hardware - The Speed controller is as in the picture (unfortunately I have no knowledge of these as on my standard models i use either Mtronics or FTX ESC's) - I am using a NiMh battery rated at 7.2v 8000mah (sourced from Aliexpress) - so far I have avoided LiPo batteries - as I have a collegue that has had two workshops burnt to the ground with Lipo batteries although I have no more details than that.
My thoughs - Either the ESC is naff or there is a problem using a NIMh battery with the ESC/Motor combination - what are your thoughts - I dont know where I could source another ESC in the UK and how expensive it would be - I dont want to spend a fortune as I cant think of where I would use another ESc of this type. As regards Lipo batteries as I said so far I have avoided the due to the fact they are expensive and I would need to buy a new Lipo charger again an expensive option in the UK but this could be used in other models.
Anyway guys what are your thoughts, any advise appreciated.
Have a good weekend everyone

I've Seen this before. When you Open the throttle this increases the amp, the battery can't deliver, the voltage goes down. Because of Low voltage the esc shuts down.
Another possible solution is to power the receiver with a separate battery, remembering to disconnect the red wire in the esc. The easy way to do this is to use an extra servo lead and cut the red wire and connect the esc to the extension lead and then into the rx.
Hope this helps.
