I have a pack that was given to me to replace the one I made in 2000 I lost in a fire last year.
It has a GBfan light board in it. When it was given to me it worked fine but shortly it stoped working. And by that I mean just the bottom led in the power bar will blink about once every 5-10 seconds.
I think the battery pack maybe bad but want to get some input before getting a new one.
Could this be a sign or low amps. Or Voltage?
