So I had this T-180 that the BEC went out on and then the LVC went out, so it only put out a fraction of the voltage. With help from members of this forum I set it to no cell protection and it's back up and running.

Don't know if that contributed to the issues but it sure looks to be blocking water from cooling the ESC. 3 out of the 4 fittings were like this.

And this is how it looks crammed in my Spartan:


Epoxied some caps on the center openings and installed some 7/32 pieces of brass tubing. It all came together with 5 minute 2 part epoxy. Haven't tested it on the water but it doesn't leak and water flows through with little to no resistance.

Thanks for looking
