amp control question
(OP)
i have a bank of 12 V batteries, charged by solar cells, that i want to run a wireless camera with.the cam requires 12 volt 80 mA source.i also have a receiver that requires 500 mA at 12 volts,that will be seperate from the camera. what is the best way to control the amp problem so they don't fry.appreiciate some advice-this is not my speciality.thanks

This is a total of 580 mA that is possible to take from one battery.
The supply wires of the differend units needs to go directly to the battery, in this there is no influence of the differend currents.
This is only if the impedance of the battery is low.
If the impedance of the battery is high the voltage drop will be greater and the charging from solar cells will be higher, this not danger for your Scells because the impedance of the cells.
It could happen if the battery will get a short but if the battery is low there the impedance gets higher and limits the current.
