Charging and Discharging a battery at the same time?
from solar panel to the battery: i understand that a charge controller is necessary to regulate power to the battery, as well as prevent overcharging it.
from the battery to boombox: most projects use an inverter directly from the battery. I'd like to avoid this step and pull dc from the battery directly to the battery box in the stereo(the ac input of the stereo converts it back to dc again anyway i think). From what i've read, inverters have a protective circuit that prevent the battery from becoming dangerously undercharged as well as regulate power from the battery. Could i just build one of these discharge controllers and be done? Is a discharge controller necessary?
cliff notes: what dangers are there in charging and discharging a battery at the same time, and how can i prevent them?
