Lipo damage- incident at club
« on: January 28, 2019, 01:19:17 PM »
On Sunday I had to condemn a club members lipo battery that had only been charged twice :-[. Sadly it had been significantly damaged in a racing boat fitted with a brushless outrunner motor. The battery became loose and in contact with the rotating mass of the outrunner. On an outrunner the entire motor casing rotates at high speed. The hard metal of the motor can cause severe damage to the relatively soft lipo casing.

 It is essential that lipos fitted in fast boats fitted with outrunner motors are securely fastened in place. Lipos used with inrunner brushless motors are not such a problem so long as the lipos cannot come into contact with the rotating motor to shaft coupling. Any doubts see me at the club.

 Sadly I envisaged the possibility of such an incident occurring when lipos and outrunner motors started to appear. I said so in one of my magazine articles but obviously I take no pleasure at all in the point being so graphically proven on Sunday. Lipos must be taken care of, they are inherently dangerous.
