I borrowed a BBB 500 LUMEN front light at the weekend for a night time event.
I charged it up on Friday and checked that it was working OK. When I fitted it to the bike on Saturday evening it was completely flat.
Has anyone else had problems with this light? Do they loose their charge that quickly if left fully charged? It's a fairly new light so could be covered by warranty if it's faulty.
I had another front light, Lezyne Macro, which I charged at the same time and it worked perfectly.
