Anybody know where to get or how to make a high output alternator for the sonic?
I know you have to get them respun. Most automotive shops can do it down here. Id just call around where you live.
A better option would be to use a dual battery system with a capacitor for the output.
I don't think two batteries would work how he wants? The alternator is what gives you power while the car is running. The battery is just for starting the engine or to power the electronics while the engine is off. Right?
The reason the phone will play longer is because there is a bigger battery. With the same charger it will take longer to get it fully charged unless you up the current or voltage with a higher output ie a bigger alternator. The battery will only last so long without proper charging. Yea it will take longer to discharge.The main reasons for a High power output are usually in regards to a stereo system with a really big amp.
If I'm correct he wants it to be able to run the hydrogen system, which would need a constant source of reliable power. A high power output alt would not be consistent enough IMHO which is why you would want a second battery and capacitor.
Think of it like this you leave your phone plugged in while playing a video game and it still dies on you. now you go buy a bigger battery and a morphie pack (it like an external battery for a phone) and you leave it plugged in, now you can game all night on your phone without worry.
The extra battery and capacitor will mean it gets constant reliable power.
If getting a second battery I would most likely go with two Brailles.
Assuming you are referring to the small Brailles', that would defeat the purpose. The capacities of those batteries are far less than a standard battery. There are batteries that are designed to provide a lot of power (as in starting a car) and batteries that are designed to deliver consistent output (as in the Optima Red Top).
If the equipment uses a regulated dc-to-dc converter, the source of power is irrelevant.
The number of batteries used is only important if 1. the system requires more voltage (eg. 24V), or 2. the equipment will operate for prolonged periods without the charging system.
Think of the alternator as a hose. If the equipment can drink more than the hose can supply, it either pulls from another source (battery {slow} and/or cap {fast}, and cheaper). If you increase the hose flow, the equipment won't starve. It really depends on the power demand levels and speed, and how the equipment is used. IMO, if you can afford it, the upgraded alternator is always the first step.
