Re: How much can a battery take??
It is not the battery that is the limiter, but the alternator. As long as all the wiring is sized correctly for the circuts, and a proper distrubition setup is used (fuze block) the battery can supply just about anything you can normally use, all at one time. However, if the total load is higher than the alternator rating, you will gradually run the battery down.
The total load applied when the engine is running is basically supplied by the alternator, not the battery. If the load is higher than the alternator output the battery supplies the rest, until the battery runs down. The battery is really there to supply needed current when the alternator is inactive, such as starting, and any devices turned on when the engine is not running.
Once the engine is running, you can take the battery out of the system, and everything will operate as usual.
