When you think of tactical flashlights that offer premium features without breaking the bank, the Olight S2R Baton II instantly comes to mind. Whether you’re an outdoor adventurer, emergency responder, or someone who just needs a reliable EDC flashlight, this device stands out with its blend of performance, portability, and practicality. In this Olight S2R II review, we’ll explore why this compact light is considered a favorite among flashlight enthusiasts and how it compares with alternatives like the Olight S1R Baton II and Baton 3.
Can your current flashlight offer a magnetic charging tail cap, 3200mAh rechargeable lithium battery, excellent runtime, and waterproof durability—all in one sleek package? If not, you might want to give the S2R II a serious look.
Why the Olight S2R II Stands Out
The S2R II is designed with the needs of real-world users in mind. From its powerful 1150-lumen turbo mode to its lightweight, pocket-friendly frame, this flashlight is perfect for everyday carry (EDC), camping, hiking, and even professional use.
Key Specifications at a Glance:
- Max Output: 1150 Lumens
- Beam Distance: 135 meters
- Battery: 18650 3200mAh lithium-ion
- Charging: Magnetic MCC II Charger
- Waterproof: IPX8-rated (2 meters)
- Weight: 98.5g (with battery)
- Modes: Moonlight, Medium, High, Turbo
Let’s now dive deeper into the unique features and real-life usability of this flashlight.
Compact Design & Portability
One of the most loved features in this Olight S2R II review is its ultra-compact form. The flashlight weighs just 3.4 ounces (98.5g) and is only 3.9 inches long—making it one of the easiest high-lumen flashlights to carry daily.
You can easily slip it into your pocket, attach it to your cap, or secure it with the stainless steel pocket clip. It also includes a lanyard and carrying pouch, enhancing its portability. Whether clipped inside your bag or carried around your neck, it never feels bulky.
For users looking for a smaller alternative, you can also explore the Olight S1A Baton, which supports AA batteries and offers a slightly different use case.
Advanced Magnetic Charging System
A major convenience upgrade in the S2R II is the second-generation MCC II magnetic charging cable. This tail cap charger allows for easy and fast charging—simply snap the magnetic charger onto the base, and it begins charging without needing to remove the battery.
The device can also operate while charging, which is especially handy during emergencies. Want to know if it’s done charging? Just check the LED power indicator—red means charging, and green means fully charged.
Additionally, unlike USB-C or micro-USB ports, there’s no risk of water ingress, making this flashlight more durable in the field. This charging method is identical to what we see in the Olight Seeker 2 Pro, a higher-end tactical model.
Brightness Modes and Beam Distance
Despite its compact size, the S2R II packs an incredible punch when it comes to illumination. It offers four standard brightness levels—moonlight, medium, high, and turbo—alongside a strobe feature. Here’s a quick breakdown:
| Mode | Lumens | Run Time | Beam Distance |
|---|---|---|---|
| Moonlight | 0.5 | 60 days | 1 meter |
| Medium | 120 | 14 hours | 15 meters |
| High | 400 | 4 hours | 80 meters |
| Turbo | 1150 | 3.8 hours | 135 meters |
The beam style combines both flood and throw, ensuring you can see wide areas as well as long distances. Its Total Internal Reflection (TIR) lens ensures a clean, balanced beam with no dark spots. The beam intensity peaks at 4600 cd and a throw distance of 147 yards.
Power Indicators, Waterproof Rating, and Battery Performance
A flashlight isn’t just about brightness—it’s about reliability. The Olight S2R Baton II makes it easy to track your battery life and ensures your light won’t unexpectedly fail during critical moments.
Smart Power Indicators
The S2R II is equipped with a three-level power indicator system embedded around the side switch. These colors give you real-time battery status:
- 🟢 Green: Battery above 70%
- 🟡 Yellow: Battery between 15% and 70%
- 🔴 Red: Battery below 15%
This small but powerful feature ensures you’ll always know when to recharge, preventing unexpected blackouts.

IPX8 Waterproof Rating
No one wants their flashlight to fail in a rainstorm or drop into a stream. Thankfully, the S2R II comes with an IPX8 waterproof rating, making it submersible up to 2 meters. Whether you’re camping in the rain or using it in a wet environment, the Olight S2R II is built to survive.
This durability mirrors high-end tactical flashlights like the Olight Seeker 2 Pro, giving you dependable performance even in extreme conditions.
Battery Capacity and Lifespan
At the heart of this flashlight lies a rechargeable 3200mAh 18650 lithium-ion battery. This high-capacity cell powers all the brightness levels and supports long runtimes, even on higher modes.
Let’s look at what this battery delivers in each brightness mode:
| Mode | Lumens | Runtime |
|---|---|---|
| Turbo | 1150 | ~230 min total (with stepdown) |
| High | 400 | ~4 hours |
| Medium | 120 | ~14 hours |
| Moonlight | 0.5 | ~60 days |
You can recharge the battery magnetically via the tail cap, making it perfect for EDC use and emergency kits.
Everyday Carry Accessories Included
The S2R II comes with a thoughtful bundle of EDC-friendly accessories:
- 🔵 Black and blue dual-direction pocket clip
- 🔵 Lanyard for hand-free use
- 🔵 Battery organizer from LumenTac
- 🔵 Carry pouch for convenient storage
All these additions make the flashlight easy to grip, carry, and store, whether in your jeans, backpack, or emergency gear.
