Hi everyone,
Is it possible to use a 555 timer to open a small 12VDC circuit when the system voltage drops to 9 volts. The system normally operates between 13V down to 10V under load (1.5amp motor).
I'm using a small rechargeable .8 amp sealed lead acid battery as the power source, and a small 12V receiver for wireless power connection to a micro motor.
The receiver has a constant power draw on the battery.The constant power draw during operation of 3 hours is no problem. However people forgetting to disconnect the power after use is. The receiver drains the battery (in around 24 hours) to 0V. Everyday recharging is not possible after that.
Can a 555 timer be wired to shut the system down around 9V, and then resupply power when the battery is recharged? Is there something even simplier I could use? These will be used in large quantities and need to be easy to assemble and inexpensive.
I greatly appreciate any help.
Dave
