Hello, can you clarify exactly what the LEDs are telling me. I see a red and a green but a bit unclear as to their purpose. Until now, my applications have had the unit in model locomotives so not seen. I am now using one as a battery backup for a clock I am making and the LEDs are behaving oddly e....

Units ordered yesterday arrived this morning!

First one I tried to replace the one that was giving problems worked perfectly.

Sales replied to me immediately to arrange a credit.

Fantastic customer service!

Thanks. Yes, I'm supplying the "in" with 5V. I'll email sales. Meantime, I've ordered more (before I found this forum) given the others worked and I've other projects on the go.

I've used 2 of these already with success. However, my third will charge the LiPo fine but the variable output sits at about 30V irrespective of the pot setting. Input is 5V regulated and the setup is the same as the others that have worked. Anyone any ideas or is it maybe a duff unit? Thanks.
