When you think of compact tactical-style flashlights with premium features, the Olight S2R Baton II is a model worth remembering. Whether you’re an outdoor enthusiast, emergency responder, or someone who needs a reliable everyday carry (EDC) flashlight, this compact light offers an appealing combination of brightness, portability, and convenience.
In this Olight S2R II review, we’ll explore its performance, battery life, magnetic charging, waterproof construction, and practical features. We’ll also compare it with the S1R Baton II, Baton 3, and newer alternatives.
Can your current flashlight offer 1150 lumens of maximum output, magnetic tail-cap charging, a 3200mAh rechargeable battery, and IPX8 water resistance in a pocket-friendly design? These are some of the features that made the S2R Baton II popular among flashlight enthusiasts.
Why the Olight S2R Baton II Stands Out
The S2R Baton II was designed for people who need strong illumination without carrying a large flashlight. Its maximum 1150-lumen turbo output, convenient magnetic charging, and durable aluminum construction make it useful for camping, hiking, household emergencies, and everyday carry.

Let’s examine how these features affect everyday usability.
Compact Design & Portability
One of the most appealing features in this Olight S2R II review is its compact construction.
At approximately 3.94 inches long and 3.47 ounces (98.5g) with the battery installed, the flashlight is comfortable to carry in a pocket, backpack, or everyday gear pouch.
The aluminum alloy body features a textured grip that provides better control during use. Its compact size also makes one-handed operation easy.
Another useful feature is the dual-direction pocket clip, which allows the flashlight to be attached in different positions. You can even clip it to the brim of a suitable cap for hands-free illumination.
The magnetic tail cap provides another hands-free option by attaching the flashlight to a suitable steel surface.
However, the magnet may not hold securely on every metal surface, particularly when the surface is painted, uneven, or subject to movement.
For users who prefer AA-powered flashlights, the Olight S1A Baton review covers a smaller alternative with a different battery system.
Advanced Magnetic Charging System
A major advantage of the S2R II is its magnetic charging system. Instead of opening a rubber charging-port cover or removing the battery, you simply attach the compatible magnetic charging cable to the tail cap.
This feature makes daily charging convenient, especially if you use the flashlight frequently.
How Magnetic Charging Works
- Turn off the flashlight.
- Connect the compatible Olight magnetic charging cable to a suitable USB power source.
- Attach the magnetic connector to the flashlight’s tail cap.
- Check the charging indicator on the cable.
- Disconnect the charger when charging is complete.
The charger indicator displays red while charging and green when charging is complete.
Because the charging contacts are on the exterior, the flashlight does not require an exposed USB port in its body. However, the contacts should be kept clean and dry before charging.
Unlike newer USB-C flashlights, the S2R II requires a compatible Olight magnetic charging cable. This can be inconvenient if the original cable is lost.

Olight S2R II Brightness Modes and Beam Distance
Despite its compact size, the S2R Baton II delivers impressive lighting performance.
It includes five brightness settings, allowing you to choose between very low illumination and a powerful short-duration turbo output.
| Mode | Brightness | Manufacturer-Rated Runtime |
|---|---|---|
| Moonlight | 0.5 lumens | 60 days |
| Low | 15 lumens | 100 hours |
| Medium | 120 lumens | 14 hours |
| High | 400 lumens | 4 hours |
| Turbo | 1150 lumens, stepping down to 400 lumens | Approximately 2 minutes at initial Turbo, followed by 230 minutes at reduced output |
| Strobe | Flashing output | Not separately specified |
These are manufacturer-rated figures under specified testing conditions. Runtime and brightness can vary with temperature, battery condition, and operating environment.
How Bright Is the 1150-Lumen Turbo Mode?
The S2R II can produce up to 1150 lumens, making it bright enough for inspecting outdoor areas, navigating dark environments, and locating objects at a distance.
However, 1150 lumens is not maintained throughout the entire rated runtime. The flashlight automatically reduces brightness after approximately two minutes to manage heat and battery consumption.
This is normal behavior rather than a product defect.
The flashlight uses a Total Internal Reflection (TIR) lens, producing a balanced beam with useful spill illumination and a defined central hotspot.
Its maximum rated beam distance is 135 meters, with a peak intensity of 4600 candela. Keep in mind that beam-distance ratings do not mean objects at that distance will be brightly illuminated for detailed inspection.
Power Indicators, Waterproof Rating, and Battery Performance
A flashlight isn’t just about brightness. Reliability, battery monitoring, and weather resistance are equally important.
The Olight S2R Baton II combines these features in a compact design that works well for everyday activities.
Smart Battery Level Indicator
The S2R II includes a three-color battery indicator integrated into its side switch.
- Green: Battery level above approximately 70%.
- Yellow: Battery level between approximately 15% and 70%.
- Red: Battery level below approximately 15%.
This makes it easier to decide when the flashlight needs charging before an outdoor trip or emergency.
However, the indicator gives an approximate battery level rather than an exact percentage.

IPX8 Waterproof Rating
No one wants a flashlight to stop working during heavy rain or after an accidental drop into water.
Thankfully, the S2R Baton II has an IPX8 water-resistance rating, with the manufacturer specifying immersion protection up to 2 meters.
This makes it suitable for use in rain, wet outdoor environments, and situations where accidental water exposure is possible.
However, the IPX8 rating does not make it a diving flashlight. Water resistance also depends on the condition of its seals and proper assembly.
Important: Allow the charging contacts to dry completely before connecting the charger. Avoid charging the flashlight immediately after water exposure.
Battery Capacity and Lifespan
The S2R Baton II uses a customized 18650 rechargeable lithium-ion battery with a 3200mAh capacity.
This battery provides a good balance of size, power, and runtime, especially for a flashlight measuring less than four inches long.
The battery supports up to 60 days of rated operation in Moonlight mode. At brighter settings, runtime becomes much shorter because the LED requires more power.
For longer battery life:
- Use Low or Medium mode whenever possible.
- Avoid unnecessary Turbo operation.
- Recharge before storing the flashlight for extended periods.
- Keep the battery away from excessive heat.
- Use a compatible Olight replacement battery when necessary.
Everyday Carry Accessories Included
Olight supplied the S2R Baton II with several useful accessories to make carrying and charging easier.
- Dual-Direction Pocket Clip: Allows flexible pocket and cap attachment.
- Lanyard: Helps prevent accidental drops during handheld use.
- Carrying Pouch: Protects the flashlight during transport and storage.
- Magnetic Charging Cable: Allows convenient battery charging.
- Rechargeable Battery: Customized 3200mAh 18650 lithium-ion cell.
These items were included in the standard manufacturer’s package. Third-party bundles may differ, so check the product listing before purchasing.
Olight S2R Baton II Controls and Useful Functions
Another advantage of the S2R II is its convenient side-switch operation.
The flashlight offers several useful functions without requiring multiple physical buttons.
How to Change Brightness
- Turn On/Off: Press the side switch once.
- Change Standard Brightness: With the flashlight on, press and hold the switch to cycle through Low, Medium, and High.
- Moonlight: Press and hold the switch while the flashlight is off.
- Turbo: Double-click the switch.
- Strobe: Triple-click the switch.
The S2R II also remembers certain previous brightness settings. Turbo is recalled as High, while Strobe is not stored in the normal mode memory.
Lockout and Timer Features
The flashlight includes an electronic lockout mode to help prevent accidental activation inside a pocket or bag.
To activate lockout, press and hold the switch while the light is off until it enters lockout mode. Hold the switch again to unlock it.
It also includes 3-minute and 9-minute automatic shutoff timers.
These features are useful when using the flashlight as a temporary reading light or when you want it to switch off automatically.
Feature Comparison: S1R Baton II vs. S2R Baton II vs. Baton 3
To understand how the S2R II compares with other compact Olight flashlights, let’s examine the original S1R Baton II and Baton 3.
| Feature | S1R Baton II | S2R Baton II | Baton 3 |
|---|---|---|---|
| Maximum Brightness | 1000 lumens | 1150 lumens | 1200 lumens |
| Maximum Runtime | 8 days | 60 days | 20 days |

The S2R Baton II offers much longer maximum runtime because of its larger 18650 battery and low-output Moonlight mode.
The Baton 3 is smaller and slightly brighter, making it more attractive for people who prioritize compact dimensions.
One important correction is that the Baton 3 flashlight itself uses magnetic charging. The Baton 3 Premium Edition also includes a portable charging case with USB-C input.
What About the Olight Baton 3 Pro?
The Baton 3 Pro is especially relevant in 2026 because Olight introduced it as the direct successor to the S2R Baton II.
It offers several improvements:
- 1500-lumen maximum output instead of 1150 lumens.
- Improved textured body for better grip.
- Proximity sensor to help reduce excessive heating near nearby objects.
- Updated side-switch design.
- Magnetic charging with a customized 18650 battery.
