I doubt that

which charger has that?

Opus 3100 has an internal switch that can be set to 3.7v, 4.2v or 4.35v. I've been using that.

aaah - i remember!

thanks

JasonWW:

Why make a mode that stops at 3.7v when you can just take the battery out yourself at whatever voltage you want?…

To charge LiFePO4 cells. This charger does not support 3.7V or 4.35V chemistries, which most people will never need anyway. Multi-chemistry support is indeed mostly just for feature fluffing.

As others said, 3.7V limit is also useful for storing li-ion cells in their “relaxed” state. Even this is questionable, however, as they will still self-drain and require routine “halving off”. In actual “storage”, this maintenance seems unlikely to happen.

Adjustable voltage limits are useful, regardless. I’m pretty sure that TK charges her cells to 4.15V to avoid 100% top-off. I would do something similar if I could. Yes, this is unnecessary as our cells are quite durable even when kept at 100%, but some of us are geeks in different ways; I’m an optimizer by nature.

Imagine how annoyed I am that I cannot “fix” my smartphones to keep them from killing their own batteries :smiling_imp: . The desire for longer runtime right now means that they sacrifice long-term battery life. If there was just a setting to reduce the max charge to 96% or so like there is on my laptop…

Dang, it looks like I’ll be spending money on a Folomov Pen L1.

I like the C2 that I’ve had for a couple weeks.

LightObsession · 2019-06-07T22:27:47.000Z

Is $25 the discounted price for the Pen L1?

Thanks.

no

LightObsession · 2019-06-08T05:58:54.000Z

I just noticed that the published outputs for the L1 are the same as for the EDC C1, even though the battery in the L1 is 2x as big.

This doesn’t seem likely that that the two lights have the same capacities.

Anyone know the actual specs for the L1?

M4D_M4X · 2019-06-08T07:18:11.000Z

got both colors - funny how the color change with different lightsource

That Pen L1 is rather interesting. The specs listed are a little weird though - It looks to use a specialty internal USB charged 10900, but the text also says it runs on 10440 and 10400, depending on where you look.

saypat · 2019-06-10T21:45:23.000Z

I like that the Pen L1 is substantially shorter than a (2) AAA light.

I noticed those discrepancies, also.

I suspect that they copy and pasted from the C1 information and didn’t proof read very thoroughly. The published output specs are the same for the C1 and L1, and they probably shouldn’t be the same.

Those errors will confuse a lot of people.

Folomov Pen L1 webpage on Folomov's website

http://www.folomov.com/en/content/?141.html

It does look like it uses a really special-looking 10900 lithium ion battery, which has a built-in charging port (otherwise, no current charger can charge 90mm length batteries (maybe a magnetic charger with a low-charge current will work)

I wonder if the 10900 is about twice the capacity of 10440, since it looks to be about twice as long?

Or maybe can we substitute 2x AAA NiMh/Alkaline batteries (but voltage may be too low?)
