Hi i basically want a DC 12v ups, for a sercurity system.
they do exist but thus far seem rare and expensive,
So I had the idea of using a battery Blue power ip67 charger to power the cameras/ led/ alarm system, while also charging a battery.
The charger is a 7 Amp, the systems draws between 1-5 amps, usually less then 2 amps.
Will the battery get properly charged and maintained, or will the fluctuating load mess up the charger's charging capability resulting in poor battery life span?
I think if the charger used volts to determine its status it would be ok but if it uses current than not so.
I plan to use one or two 7AH sealed lead acid battery, would it make any difference if i used lithium?
