Protect a battery from overcharging to prevent damage on the battery. 
This is a demonstration on changing a 5V battery by using a capacitor.
* Switch the switch to discharge and charge the capacitor to see the charging effect.
*The LED will change from red to green when the battery is fully charged.

U may change the 5v zener diode to 4v and the 715ohm resistor to 550ohm.

Hi, I have two solar panels each panel is 24v so how can i charge from 24v to 12v batteries?

Nadir >> connect your solarpanels in parallel and your batteries in series.

Need thermal compensation, if use this for Lithium Bat.

Karlberg > batteries need to be balance charged. Putting them in series needs an extra balancing lead and balancing charger to make sure the batteries are charged to the same level. If the charge level of the batteries is different, you run the risk of overcharging/overdischarging one of the batteries

Awesome, it was quite simple to derive one to 3.7 volts with parts I may. I'm going to build it! Maybe even for 5v USB!
