Strange esc problem

[stadiumyamaha]

Anyone ever see this happen? I've been having a seaking 180 go low voltage very early, like after 30-45 seconds the last couple of runs in my sons mg. this time I turned the lv cutoff off and ran it for 4 minutes. Boat didn't run especially well and seemed to drop off quickly. once I got back home the batts were very warm and the volts of each cell were all over the place. Both batts are reading within a couple of tenths of each other on every cell. Here's the weird part. The readings are as follow on both sky 4s 40c 4000mah.
4.35 1.68 5.35 5.38 I did know your esc could charge as wel as discharge cells. Lol
The batts are fresh and balanced well before this run. I know there shot now. I've just never seen this before.

Your lipo is shot.

There's no doubt. I've just never had this happen before.

Your battery has most probably been shot, but if you are using a cell checker of some sort to check the cells, you are not getting the full story. There is no way that two of the cells are over 5V.
Use a digital multimeter to check the voltage of each cell at the balance plug. I'd say only one cell is dead.

How old were the Lipo's.
