Sounds like a single dummy AAA and a single 3.7V li-ion AAA would support the listed runtimes (since those are for a different model with a smaller battery).
Sorry, I thought that you were suggesting that the 10900 battery in the L1 is a 10440 with a dummy cell all under the same skin and that’s how Folomov got their specs. Someone else had suggested that before, but the 10900 capacity test performed by a member showed twice the capacity of a 10440.
If you want to use a 10440 plus a dummy 10440 cell, that might possibly work to get the same runtimes as the C1, which actually runs on a 10440.
Yes! Using a 10440 plus a dummy cell should be the equivalent of using a 10900 with half a charge, which would give the runtimes of the C1. And the reason I posted it is because finding a spare 10900 is very difficult (I haven't found a supplier yet).
I received my two today - they were reshipped after I contacted the seller 8/29/19 - they had been returned to China for some reason.
Very 1st impressions right out of the tin:
Very, very dim moonlight.
Very tight pocket clip - the tightest I’ve had on a pen light.
Mode sequence is LMHML. I was really hoping that it would be LMHLMH as my C2 is. I still don’t like the LMHML mode sequence.
I like the beam profile.
The runtime and output specs are the same in the manual as online, so I still don’t know what the actual specs are and don’t have a way to find out, since I don’t have a C1 to compare them to or a light meter.
