You mentioned ot make sure it passes the required amps... and put 5 amps..
each of these 3 legged guys seems to be 1.5 amp or 1amp, my panel only puts out like 1.25amp max i think.
where are the 5amp 6v ones you mention?
also, so am i just wiring one of these three legged little guys in line to the battery. you said no diode needed, but what about at night when the battery wants to send voltage toward the solar panel, isnt that why diodes are used? to prevent battery loss?
