Have you or a friend got a good old fashioned 'trickle' charger?

If this is an 11.1v LiPo as I gather from your other posts, and its down to 8volts, I think the battery is probably dead as you've discharged it too far. Your ESC should not have allowed this to happen if it is set up correctly {:-{

Time for a new battery (larger capacity) and make sure the ESC is set up correctly. Normal cutoff is 3 or 3.1volt per cell - 9 or 9.3 volts in your case.

Hi Barrie,

On my setup card, there is Reverse Power, Start Power, Drag Brake, Battery type then Setting ( automatic or Manual) where would the battery cut off be?

I think your right, bigger.  :-))

There are ways to sometimes bring back a dead lipo if its not too far gone but its not reccomended and can be dangerous

If you set Battery Type to LiPo, it should set the cut-off voltage, although you probably have to tell it how many cells (3) as well.
