Wireless Li-Ion Battery Charger Circuit
Charging batteries through inductive wireless charging is one of the applications that’s becoming very popular and getting appreciated by the uses. Here we’ll study how to make a wireless Li-Ion battery charger circuit using the same concept. Any electrical system which involves wire networks or cables can be very messy and cumbersome. Introduction Today the […]
High Current Solar Battery Charger Circuit – 25 Amps
This circuit is capable of providing as high as 25 Amps of current at any specified voltage between 1.25 V to 30V as per the adjustment of the given pot. The current is constant irrespective of the voltage settings. The circuit can be used for charging batteries in range of 50 to 200 AH. How […]
Make a Battery Charger in 15 Minutes
I have posted many battery charger circuits in this site, some are easy to build but less efficient, while some are too sophisticated involving complex construction steps. The one posted here is possibly the easiset with its concept and also is extremely easy to build. In fact if you had all the required material you […]
Battery Charger Problems Troubleshooting Discussed
The included battery charger circuit was designed and built by Mr.Vinod Chandran, however there’s some issues and problems with the circuit the troubleshooting of the same is addressed in this article. I have explained the discussion between Vinod and me. Discussing a Transistor Battery Charger Problem Vinod: I am attaching the circuit image of the […]
