battery issue...

That vid was interesting.... It acted like it wanted to stay running... That bat looks like it would have come out of an r/c car... He should have used 2 of those batteries... It might have worked a little better:)

Yes it is a RC battery. There is a lot wrong with using that battery as is in that application. But if the FJ was working like it should it would have started. What is interesting is power the battery had to keep turning it over.  IF you wanted to use that type of battery you would have to add a PCM board to it.  The cells have to be balanced while charging,  heat has to be monitored,  low voltage cut off and high voltage switch needs to be installed and a dead short cut off.

RC battery's as a rule do not have any of that built in as they are charged outside with a separate charger. The leads on a RC battery have the normal + and - and if you notice there is another set of wires attached with a plug. That plug is attached to the external charger to do the above balancing and monitoring while charging.  

If you take apart a lithium battery designed for auto or motorcycle use you would see a nice circuit board in side them to control the variables to keep the battery in spec.  If you took apart a laptop battery or camcorder battery you would also find a small circuit doing the same.

There are a lot of people here that know more about batteries than I do.  The purpose of the video was to demonstrate the cranking power that a small RC lithium cell has.  I can't see the voltage rating of his battery in the video but it probably is a 14.8 volt unit at around 4 amps. If it would have started and the generator kicked 15 volts at it then it would be toast in short order.

   If that bloke had any idea on how to start an FJ, it would have started easily and kept running.
