hello I have power in the charger , but the battery and controller won’t charge ?
is there away of testing the battery etc
just showing one green bar of light
many thanks
If two different batteries cannot be charged, I’d question the charger itself or the power source it’s plugged into.
When did that charger last charge those batteries as expected? What changes since then?
The easiest test would be to try a different charger that is known to be working as expected. I suppose tools exist to test batteries/chargers, but that’s outside of my wheelhouse.
