Niwalker Aurora C26 XP-L HI

I bought this 1x26650 thrower from Andrew & Amanda for $42 last January (2017).

I am very pleased with the light.

However, it does have what seems like a high parasitic drain.

In one or two months of non use, the battery gets drained.

I plan on unscrewing the tailcap from now on.

Anyone else have this problem?

I’ve read about it: FlashLion Reviews: Niwalker Aurora C26, Prototype (Cree XP-L HI)(1x26650)
Basically within a month your battery is depleted.
A lot of Niwalkers have fairly high drain values. The MM18 (tested by the same guy) also suffers from extreme high values.

my light shut down and the battery read 2.9 volts or so. Does this mean that it would not deplete the battery to a dangerous level?

This is only the case when the light is switched on; then the low voltage protection will kick in and shut the light off. However, the problem is that there is a high parasitic drain when the light is off, and from what I’ve read, the driver is not going to shut itself/circuit off. This means that the light will keep on depleting the battery until 0 Volts when the light is off (=on the shelf not being used for a couple of weeks). This is the case if you have an unprotected cell. If you have a protected cell (don’t know if it fits), then the protection circuit of the battery should kick in.
I have little understanding of drivers and stuff, but I think this is correct.

Edit:

Here’s the issue explained with the Niwalker MM18: NIWALKER Nova MM18 (1.XM-L2 + 2.MK-R)(4x18650)(Lots of Pictures)
A problem with the MM18 is that the light requires high drain cells, therefore they are unprotected. Back then you didn’t have protected high drain cells.
