Hello all,

Now that my seaspray is up and running, using a Photon SBS 12.0T 3300 Kv motor 60 amp ESC combo and a 35mm S prop. I have noticed after a a few fast runs the motor is very hot but the ESC and batts are cool, then after 5 of use the boat dies in the middle of the pond, once in, the Voltage is done to down to around 8 volts.

Is this the engine working hard and using up the Lipo power if so do I need a bigger capacity batts, lower KV motor or smaller prop?

There is no water cooling at the moment.

Cheers CP

Peter,

Thank you. I'm trying to find out at the moment how by using the programme card I can set the voltage cut off, the battery is a 11.1v 3s 2200 mah overlander, Yes I have read some info on lipo  but we all have to start somewhere.

I have a Photon 1/10 SBS 12. motor and 60A esc combo

no watercooling is the reason, it may be a 60 amp esc but only when cooled , they use water to replace a big chunce of metal as a cooler so it has to have water it is prob shutting down due to overheating.
