Did you have your meter set properly?

Any advice to settings would be appreciated, I am not an electrician.

Two suggestions:
1. Can you post a photo of your meter set up to measure voltage.
2. What does your meter read when you put the leads on a 12V car battery or a 1.5V battery?

Some batteries require to be switched on to get reading, mine do.

OK, that shows that your meter is reading volts correctly, no need for a photo.

Ok thank you

Thanks will try that

That’s worked novices error, charged them until green light, now reading 41.6 is that ok? Thanks

Not if he's on the wrong voltage scale.

41.6 is good and charge may vary a little from 41.5 - 42v when fully charged.
Some switch off when green light appears others like me leave them to fully balance for another 1 -2 hrs after green light. The forum's troll will likely pipe up and as usual disagree.
A battery switch is usually a BMS switch, so needs not only turning on to use the bike but also for correct balance charging.

Unlikely that an overange measurement would indicate close to 0.
