This is a Simple 10 Amp Solar Charge Controller Circuit Diagram . The SCC2 is a solar charge controller, its function is to regulate the power flowing from a photovoltaic panel into a rechargeable battery. It features easy setup with one potentiometer for the float voltage adjustment, an equalize function for periodic overcharging, and automatic temperature compensation for better charging over a range of temperatures. 10 Amp Solar Charge Controller Circuit Diagram The goal of the circuit design was to make a charge controller with analog simplicity, high efficiency, and reliability. A medium power solar system can be built with a 12V solar panel up to 10 amps, the SCC2, and a rechargeable battery. The SCC2 works with lead acid, NiCD and NiMH batteries with ratings from less than one to several hundred amp-hours. With the appropriate parts selection, the SCC2 can be operated at 6V, 12V, 24V or other voltages. Specifications: Maximum solar panel current: 10 Amps Night time battery drain...

Small-size AA cells and button cells used in electronic devices providing a terminal voltage of 1.5V are normally rated at 500 mAh. As the cells discharge, their internal impedance increases to form a potential divider along with the load and the battery terminal voltage reduces. This, in turn, reduces the performance of the gadget and we are forced to replace the battery with a new one. But the same battery can be used again in some other application that requires less current. Here’s a simple tester for quick checking of discharged pencells and button cells before throwing them away. The tester detects the holding charge of the battery and the terminal voltage to indicate whether the battery is suitable for a particular gadget or not. A 9V battery can power the circuit with sufficient voltage and current. When you close switch S1, it provides stable 6V DC to the circuit. Simple Pencell Charge Indicator Circuit Diagram The circuit uses op-amp CA3140 (IC1) as a voltage comparator. It c...

Why you may need a zipcharge quick charger? With so many devices around these days, making sure they have enough juice to run on is essential wherever we go. The Zipcharge Quick Charger aims to help you out with that, where it comes in the form of a rechargeable power stick that takes a mere 15 minutes of charging to provide your iPod with another 20 hours of audio playback, while you get 10 more hours of talk time. Now, these are all theoretical figures, so you might want to take it with a pinch of salt. How about a 60 second charge that offers 2 hours of playback on your iPod? Charging the sleek ZipCharge for a paltry 15 minutes will store enough oomph to give your iPod an extra 20 hours of playtime or your mobile phone an additional 10 hours of talk time. If you’re in a pant-trippingly awful rush, a 60 second charge whooshes in sufficient juice to power an iPod for 2 hours, a mobile phone for 8 hours, 2 Way Radio for 1 hour 20 mins or a camera for 80 photos. So how does it work? No...
