Li-ion Battery Charger with TL431 This is a simple to build charger for single 3.7V lipo battery. The heart of the charger is TL431 shunt regulator that controls the incoming current. Charger comes with a convenient charging LED indicator. As charging current goes down so does the intensity of the LED.

Intelligent NiCd/NiMH Charger/Cycler with 128×64 Graphical LCD The accu cycler project presented here is an excellent solution for charging and discharging NiCd and NiMH accumulators for R/C modelers and others who make use of these accumulator types. With its performance it is very close to the many of the commercial products available on [...]
Intelligent NiCd/NiMH Battery Charger This cheap and easy to build NiCd/NiMH Battery Charger is suitable for automatically charging a wide range of batteries for many applications. Proper chargers are usually expensive and cheap chargers supplied with the original equipment often incorrectly charge the cells and dramatically shorten their life. This ‘intelligent’ charger was [...]
Fast PIC NiMH / NiCd Battery Charger This battery charger charges a NIMH 5-pack battery used in the BiPed robot in less than 1 hour, and charges the 10-pack NiCd used in the Snuf robot in about 30 minutes. To prevent overheating of the battery, the charging current is turned off when the [...]
Atmel Solar Panel Battery Charger Batwatch is a simple monitor for a solar panel battery charger, using an Atmel ATtiny13V. It periodically measures the charge current and battery voltage, and shows them by blinking two LEDs. I built this circuit into the plug of a VW solar charger panel that is used to [...]
iPOD – MP3 Player Charger Portable iPod charger that you can use while away from your computer. The circuit is based around an MC34063 switchmode regulator. This has high efficiency so that there is very little heat produced inside the box, even when delivering its maximum output current. The circuit is more complicated [...]
This trivial but very efficient circuit protects a run-acid battery (12-in opposition to solar battery otherwise car battery) critical of overcharging by a solar module once the thing light is too brainy otherwise lasts too stretched. It does so by energizing a fan, opening by a low tempo once the voltage is approximately 13.8 against [...]
Mobile phone , phone battery chargers on hand wearing the souk are quite expensive. This circuit presented at juncture comes so a low-cost alternative to charge cellular phone telephones/battery packs with a rating of 7.2 volts. Low Cost Phone Battery Charger Circuit
