What are the length of your cells? If you read though the thread over on BLF a lot of "problems" have been solved by using the correct length cells. I believe the ideal length is 67-69mm per cell. Longer and it is to tight of a fit and if shorter the cells don't make good connection.I tried Convoy L6 with non branded (but protected) 26650 but can only get 2 modes and quite dim, what might be wrong?
I'm suspecting the batteries but that's the best I can get for now. Buying from aboard will took 1-2 months because batteries cant be shipped by plane.
Actually the L6 is a constant current light drawing about 5 amps at the tail. Any quality 26650 cell will run it just fine. Most guys on BLF are using protected 5200 or 4200mah cells.L6 requires high-drain batteries.
so this might be reason
