I would be interested to know what your preference for battery type is, ie NiCd or NiMH etc Hi Noel,

Unfortunately, I'm no longer able to see the pics in your postings. Can you fix this when you get a chance? Thanks! Hi Noel, thanks for the great info.

Unfortunately I don't have any circuit for 6v charge controller. There are sources in the internet for schematic for a 12v battery but not for 6v. http://solorb.com/elect/solarcirc/scc3/ However, if you do found or created one, I would surely like to feature your project on this website. In the meantime, what I can say is that using a 1watt panel to charge your 6V 4AH battery wouldn't result in overcharging. Depending on the battery specs, there are "trickle charge" rates. Some batteries have a trickle charge rate of C/16 meaning if you have 4A battery then that would be 250ma. If your panel is delivering current lower than the trickle charge rate of your battery, then theoretically it should not damage your battery. This is the type of charging used by those emergency lights. The problem is that it would take a longer time to charge the battery if it were just doing trickle charges. Cheers, Noel Hi Wole Adu,

Thank you. Like I said Im trying to build a Led lantern, the lamp will be a 8mm 100mA white led to be powered by a 6V 4AH/20hr Lead acid battery. my problem is to design a 1 watt 8v direct charging solar battery panel to charge the battery. Also to design a circuit that will switch off the charging process when the battery is fully charged(this I saw in ur write up) also something to limit the battery depth discharge to a predetermined level of 40-50% for battery long life. I hope you can be of help I live in Nigeria where electricity is a big problem Thanks WOLE ADU Hi,

Please let me know when you have a chance. Hi Noel, I’m an editor at Popular Science, and was wondering if you’d be interested in adapting this project for the magazine.
