Hi, are you fantastic, I imply truly very good at mastering the concepts of electronics? The dilemma is that there is nothing at all to regulate the voltage output of the solar panel or avert overcharging of the battery and damaging it or the solar panel. Also identified as deep cycle batteries, solar batteries have been developed particularly to provide a charge after which sustain that charge for a lengthy period, often for hours. I ‘m now getting a difficulty figuring out how to rig 1 of these up to charge 4AA’s that are connected to eight LED’s and have a dusk to dawn circuit.
Max power comes into impact when charging a 12V battery @ 1.5A: e.g. battery voltage = 12V, solar panel = 18V. If you use your battery constantly or frequently with no other way to maintain it charged, then you ought to decide on a higher watt method to make certain you can retain up with the drain. This heat is not exactly wasted power—it is excess power that is unneeded in the process of charging a battery. Good circuit for its simplicity and effectiveness and the minimum use of components.
To obtain maximum charge in a 12V battery, set the control to 14.6V. Automotive systems further decrease voltage to 13 to 13.5V in order to accommodate high temperature operation as the battery is normally situated in the hot engine compartment—battery has a damaging thermal coefficient of voltage. The built-in rechargeable lithium polymer battery is great …Read More
