Mini BoostPack 12V Capacitor Car Battery / LiFe Abuse???

This guy is using capacitors to start his car. He added a 4200 LiFe to keep them topped off over longer periods of time. Without the battery, he says the capacitors go dead in about 3 days. Is he going to have issues charging the LiFe with this setup? Kind of interesting though.

Probably not, as long as he keeps tabs on the balance of both the LiFe and the caps...
Very cool idea though...much lighter than a regular lead acid battery!

@buggyboat, I think he won't have many issues. This is a comfortable setup considering the fact that capacitors can give an instant voltage spike for ignition. But he will be facing problems because capacitors obviously lose charge and require a battery to keep them charged so if he leaves this setup be for a longer duration of time, batteries will give up and eventually it's going to create bigger problems than the ones he's trying to avoid with this setup. It's a good idea though, with proper maintenance, it'll work.
