Joule Thief

[freepow]

@ ALL,     I have seen  rechargeable  "C" batteries rated at  9000 mA's  and  "AA" rated at  3000 mA's

              Does anyone know the maximum current I can charge these at with a solar panel ?

Can I charge the  "C" batteries with a  3 Amp solar panel ??
Can I charge the "AA"batteries with a  3 Amp solar panel ??

What minimum volts do I need to charge  2x AA battery rated at 1.25v each ?

here is a list for you
1.2v                  2-2.5v
2.4v                  3.5-4v
3.6v                  5-6v
6v                     7.5-9v
12v                   15-18v

10% of there capacity so the 9000mah would be 900mah for 15 hours 30% counting losses
3000mah would be 300ma for 15 hours i have 2500mah batterys and i charge them on my charger for 16 hours at 250ma

what you could do is use a zener diode to dump the excess current off to a load to stop over charge this was how the old motorcycle electrics worked

Hi  NickZ,  can you tell me what your JT's are using in mA's from your AA's  ,also can you post some pictures of your lights and JT's.

I have a great small box that has a 240v wall socket in it that I can plug a nice 240v(20xLED) bulb lamp with cord into it, and the jt is powered by 2xAA.

A question for you...  if I was to charge 2xAA's  how many volts would I need from a solar panel
What would be the fastest I can charge 2xAA's ?? (the max current I can charge with) ??

if your panels put out such high current you could leave the units on 24/7 and the batterys would still be charged for the night

nick would you use a voltage devider to run the jt as thats how i was thinking of doing it but on the other hand i dont think they be need to use a jt with a 12volt system
