Blue Sky - SB50DL

Hello Everyone.

Just a quick question about this controller.

When using the automatic equalization feature, the LED will flash rapidly. How do I know when the batteries have been equalized?

Thanks for everyones input and have a great weekend.

    The [magic 8 ball] owners manual should explain that

    As best I can tell, the SB50's EQ function is entirely manual. You release the EQ button to start the process, and you push the button in to stop it.

    crewzer is 100% right and be sure you never put stuff on top of the controller, even temporarilly, as it could activate the eq function. that is one complaint i do have on the sb50 as that was poorly thought out in placing that switch there.
