Subject: Re: Extended Batteries for 50ct
Pres,
I am considering taking a flexible panel that I have used on
several occasions to charge a small (3.5ah) 12v Lead-acid....This is
where weight becomes a problem....
Was hoping to just use extended and standard batts, but as
far as I can see they are all excessively priced... I thought of making
a charge adaptor to go with the panel.. have to find a safe circuit
though...
Any links?
Best Regards,
Dan Baker.
