I could really use some help. I currently have the King Of Shaves P1 35 brushless. After alot of reading I found out that people were able to run 2 Lipos in there. I have a Venom 5400 20C 11.1V that I was running just as a single battery set up. I decided to take the (2) Lipos that I run in my Traxxas and run them in my Boat. These batteries are 5000 35C 11.1. After I made my wiring set up to connect from deans to Traxxas connectors I plugged the set up in.

Well lets just say it went POOF!!! for a lack of better words. Im new to the Lipo gig but the ESC the rec the crystal everything got fried. After replacing all of these components I decided to stay with the one lipo for now. Im confused I hear people saying they are running 4s twin lipos and 6s lipos. What is the max I can go? Did I over do it with the 35C's? Any help would be greatly appreciated. Im looking to get alot more out of this boat but just don't want to keep melting this poor thing.

Thanks Tom
