Why can I recharge lead acid batteries with solar but not lithium ion?
Then I tried charging a 20 amp hour Werker sealed lead acid 12 volt battery. I set the anyvolt to 14.4 volts. The panels charged the lead acid battery at 4.5 watts. Thats pretty good.
Now why can I charge the lead acid but not the lithium. The lithium is what I really want to charge because i want to use the solar panel to charge lithium cells when I go on long bike tours. I don't want to take any heavy lead acid batteries on my bike trip.
