One of the problems that occurs with 'car-based' systems hen trying to multiple charge / demand high power - it just does not happen !
I know guys who tried setting up car based systems to charge their 6S multi systems for their Gaui Helicopters (they are a Demo team) ... they ended up with a generator.
Car batterys despite what some think - are one of the worst forms of power supply. You only get 50 - 60% power before plates start complaining .. go lower and you are likely to buckle a plate or two - then its only scrap.
High power is only for short duration and requires alternator back up.
Its not an easy one to solve. Go on any RC forum and you will find page after page of threads on field charging LiPo's ... NO-ONE has found the universal answer yet.
