Olight S1R II Baton and Olight S2R Baton II Flashlight Review

Olight S1R II Baton and Olight S2R Baton II Flashlight Review

These two Olight flashlights are very similar: the S1R II Baton and S2R Baton II. Take your pick, 16340 or 18650 support, and great size!

Throughout this review, I’ve tried to always discuss the S1RII Baton first, followed by the S2R Baton II.  The photos are generally laid out that way.  The lights are similar enough that if I don’t specify, you may assume that the feature being discussed is shared by the two lights.

Official Specs and Features

S1R II Baton
S2R Baton II


Of this current generation, there is just one of the S2R Baton II.  These are iterations, though.  There is one previous model (the S2R).  The S1R had a couple of iterations, with the S1R Turbo S being the most recent (I think, the naming gets a bit confusing.)  There are ‘special metal’ versions of the S1RII Baton, though.  There’s copper, and four titanium versions, each with a different CCT.  These models are quite nice looking, and retain the charging features of the models tested here.


S1R II Baton is $64.99 at OlightStore.com
S2R Baton II is $69.99 at OlightStore.com

Short Review

I like these lights quite a bit.  The knurling is great (seriously, I really like it), and the size of the 18650 version in particular, is fantastic.  I don’t need or necessarily want charging in lights and this is no exception, with the additional detriment of these lights needing proprietary cells.

What’s Included

Both packages are practically the same, with minor tweaks.

  • Flashlight (S1RII Baton or S2R Baton II)
  • Cell (Proprietary 16340 or 18650)
  • Velvet Pouch
  • Charge cable (USB to proprietary charge base)
  • Manual
  • Cell box (S1RII Baton only)
  • Spare pocket clip (black, S2R Baton II only)
  • Lanyard

Package and Manual

Standard new Olight packaging.  It’s a tear strip box with a serial number, and very dense packaging (ie it’s impossible to get these repackaged like-new).

Both boxes have a photo of the item and adequate specs.

Inside is some instruction for further opening, and then the lights very prominently displayed.  It’s a nice display, and a good package.

Here are pdf versions of the manuals.

Build Quality and Disassembly

I mentioned above that I love the knurling on these lights.  That’s the prominent feature, so overall the lights are a “like” from me.  Aside from that, they have very good build quality.

The threads are square-cut and adequately lubed.  One thing in particular I like about the knurling is that it makes unscrewing the body very easy.  There is no [removable] tailcap; to remove the cell, one must hold the head and unscrew the body.

Both lights have springs on the head and tail.  The tail spring(s?) are for electrical contact and aren’t in any way for impact resistance.  The springs on the head is quite stiff, though, so it should provide a reasonable amount of impact resistance.

One thing that separates these lights is a minor thing.  The bezel of the S1RII Baton is press-fit onto the light.  The bezel of the S2R Baton II is press-fit into the light.  This is important for potential mods – with the S1RII’s bezel likely being grossly easier to remove.  Interestingly this setup leads to the bezel being the same size in both, and the reflector being the same size, too.

Size and Comps

S1RII Baton Officially:

Weight (g / oz) 51 / 1.8
Length (mm / in) 63 / 2.48
Head Diameter (mm / in) 21 / 0.83
Body Diameter (mm / in) 21 / 0.83

S2R Baton II Officially:

Weight (g / oz) 98.5 / 3.47
Length (mm / in) 100 / 3.94
Head Diameter (mm / in) 23 / 0.91
Body Diameter (mm / in) 23 / 0.91

The S1RII Baton isn’t the smallest 16340 light made by Olight, but it does add the feature of on-board charging.  I would like to see this knurling on the smaller model like seen below, but with a removable body not tailcap.


Retention and Carry

These lights include pocket clips (in fact the S2R Baton II includes two!)  The pocket clip has a specific place and orientation – just opposite the switch.  This is a doubled-over clip, so technically could be carried bezel up or down, but the only reasonable way is really bezel up.  Though the pocket clip is opposite the switch, I didn’t have any problems with accidental activation, and I didn’t tend to lock the lights out.

Also included is a velvet pouch, which is perfect for the man about town.  It’s much plusher than your average Crown Royal pouch.

Power and Runtime

Both lights include cells.  The included cell is proprietary – there are both positive and negative contacts on the positive end, (and only negative on the negative end).  This facilitates on-board charging.  These lights will not charge any type cells but these specific Olight cells.  Both light will work with non-proprietary cells, but charging is not possible.

The cell fits in an unusual way (but not all that unusual for Olights).  This is required because of the charge circuit.  Normally, the positive terminal goes toward the head.  In both of these Olights, the negative terminal goes on the head end.

The S1RII Baton is powered by a single 16340 cell.

It’s 550mAh rated, and unusually, has a plastic shroud over the positive contact.  This is likely to prevent shorting, because of how the charge circuit is set up.

Here’s a runtime on Turbo.  Surprisingly, the light is quite capable, and bested the claim quite substantially.  Unfortunately, the output on Turbo doesn’t last very long, and the stepdown is abrupt and harsh, going to around 400 lumens.

Output on High has a similar stepdown, but lasts a little longer.  The stepdowns are the same as with Turbo.

In both cases, the light exhibited LVP around 3V, with the red indicator on the switch giving warning.

The charge circuit is on the tailcap, and has exposed positive and negative contacts.  It’s possible to read voltage off those, but I don’t have any steel wool to test if the circuit is “live” live.  (That said, I do think Olight learned a valuable lesson with the H2R fiasco.)

The S2R Baton II has the same charge circuit.

These lights have the same charge base, too.  And based on the charge graphs, the same charge circuit as well.  The base snaps to the light magnetically, and has a red dot on the bottom when charging, which turns green when charging is complete.

Two charge tests for the S1RII Baton.  Very similar profile, with charging at over 0.8A.  For a 16340, that’s a shade high.

On to the S2R Baton II.  The cell here is a proprietary 18650.  Any 18650 will work in the light, but only this proprietary cell maybe charged.

The runtime for this light looks like the runtime for the S1RII Baton.

Turbo lasts more than the magical 2 minute window, which is nice, and with fairly minimal fade.  At 30 seconds, the output is over the claimed 1150 lumens, at around 1370.

Unlike the S1RII Baton, this light does not seem to have low voltage protection.  These two tests stopped at 2.6 and 2.5V, which is lower than I like to take my lights regularly.  It’s certainly safe for cells at least occasionally, as that’s what most cells are taken down to for their rated capacity, but it’s not something I’d want to do regularly.  (When cell testing, I stop at 2.8V!)

Same charge base as before, and the same charge program, too.  While the >0.8A CC phase was a little high for the  16340, it’s a little low for the 18650.  Not because it’s bad for the cell, but because it takes a while to fully charge the 3200mAh 18650.  The B test below has a little bit of wobbliness because I moved some things around on my desk and disturbed the test.

User Interface and Operation

Each of these lights has an indicating e-switch on the head end of the side of the body.  The switch cover has a bit of texture and is proud enough that it’s easy to find.  It’s also not so proud or soft that it will easily activate accidentally.

The UI between the two lights is the same.  Here’s a UI table!

State Action Result
Off Click On (mode memory)^
On Hold (release at desired mode) Mode cycle (Moon, L, M, H) (no Turbo)
Off Hold Moonlight
Any Double click Turbo
Any Triple click Strobe
Strobe Click Off
Strobe Hold Previous Mode
Off Long hold (past Moonlight) Lockout
Lockout Hold Unlock to Moonlight
     On Click and Hold (quickly)^^ Timer (Single blink: 3 minutes, Double blink: 9 minutes)
 Timer Click and Hold (quickly)^^ Switch between 3 and 9 minute timers.

^ Moon, Low, Medium, and High are memorized.  Turbo is memorized as High.
^^ The manual states this as “Double click and hold” but I think “Click and hold” quickly.  Any form of double click ends in Turbo or Strobe.

LED and Beam

As stated above, the difference in how the bezel fits these lights means that the bezels are the same sizes, and the TIR is the same size too.  The bezel has the output, temp, and CRI listed.  A nice, unnecessary touch.

The emitters in these lights are not the same, however.

The S1RII Baton has a Cree XM-L2 CW.  The bezel says it’s a 6500K 70CRI emitter.

The beam profile is everything I like about TIRs – a broad spot with almost no spill.

The S2R Baton II has a Luminus SST-40, at 6500-7500K, and also 70CRI.

Practically the same beam profile between the two lights.

Random Comparisons and Competitive Options….

There’s no shortage of competition for these two lights.

S1RII Baton competitors

S2R Baton II competitors

Drilled down far enough though, these lights do stand out a bit in their categories.  In particular, I like the S2R Baton II not because of its name, but because it’s quite small for an 18650 light (much less one with charging).


What I like

  • Build quality is quite good
  • On board charging is good but would be better if tailored to each light
  • Full package includes charging and cell
  • Availability of the S1RII Baton in special metals
  • They both work with non-proprietary cells (even if they can’t charge them)
  • The UI retains neat features from previous models, like the 3 or 9 minute timer
  • I like this updated knurling (a lot, actually)

What I don’t like

  • Proprietary cells
  • Very cool tint

  2. Hey one question. Olight makes a winter version of the 1000 lumen baton II, in titanium. They no longer have that available on olightstore.com my question is do you know where I could get that flashlight? Or something g) similar that has the capability of putting out that Amber light. I’m not up on leds and their beam color, but if you can guide me in a direction I’ll appreciate it.

  3. Great site, love the reviews. How does the s1r2 baton compare to the rovyvon a28 in terms of beam pattern? Both seem to have TIR optics but wonder how they compare in terms of flood and throw.

    1. I would recommend looking at the reviews for both – there are beamshots taken at consistent distances which should show a fair comparison.

  4. Hey, one question. Does the S1R have a PWM on any mode? Really appreciate if you can help to answer my question.
