Just sounds like a very weak battery....when it is stressed to much (which it gets by aplying pressure) it just shut's off...But i also would not expect to much of a 50VOlt System. I would not drive with this unit....there is not much to help here. Seams new battery's are needed. Link to comment Share on other sites More sharing options...
