Q: What are the key features of the C7 V2?

A: Fenix C7 V2 is a high-output work flashlight. Its key features include:

1. 3300 lumens maximum output and 575 meters maximum beam distance.
2. Powered by an included ARB-L21-5000 V2.0 rechargeable battery.
3. Inner waterproof USB Type-C charging port.

Q: What kind of LED is used in C7 V2?

A: Utilizes one Luminus SFT70 Gen2 LED with a lifespan of 50,000 hours.

Q: What is the operating voltage of C7 V2?

A: 3.0 - 4.2V.

Q: Is C7 V2 rechargeable? How long is the charging time?

A: Yes. The C7 V2 is rechargeable via its USB Type-C charging port. The battery level indicator will display red while charging and will turn green when fully charged. The normal charging time of the included battery is approximately 3 hours from depleted to fully charged with a 5V/2A or above charging adapter. The C7 V2 does not support fast charging.

Q: How to prevent accidentally activating the C7 V2?

A: The C7 V2 features a lockout function.

Lock: With the light turned off, double click the side switch within 0.5 seconds, the light will blink twice in Low output to indicate the locked status.

Unlock: With the light locked, double click the side switch within 0.5 seconds, the light will activate in Low output to indicate that the light is unlocked.

Note: In locked status, any operation other than battery level indication and unlocking will activate two blinks in Low output to indicate the locked status.

Q: Why does the C7 V2 downshift to a lower mode after being used for a while and the higher mode cannot be selected?

A: There are two reasons:

1. Intelligent Overheat Protection

The flashlight will accumulate a lot of heat when used at high output for extended periods. When the flashlight reaches a temperature of 60°C/140°F or above, it will automatically step down its output level to reduce the temperature.

2. Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until the lowest output is reached.

Q: Why does the C7 V2 sometimes flicker?

A: The reasons that may cause the flashlight to flicker, shine intermittently or even fail to illuminate:

1. Poor battery level.

Solution: Recharge or replace the battery.

2. The contact or contact point of the battery or flashlight is dirty.

Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact your authorized distributor.

Operating Instructions

On/Off: press and hold the side switch for 0.5 seconds to turn the flashlight on/off.

Mode Switching: press and hold the side switch for 1.2 seconds to enter Strobe. Single-click the side switch to select between Strobe and SOS.

Output Selection: with the light on, single-click the side switch to cycle Eco → Low → Med → High → Turbo.

Lock/Unlock: with the light off, double-click the side switch within 0.5 seconds to lock (blinks twice in Low output to confirm). Double-click again within 0.5 seconds to unlock (activates in Low output).

Intelligent Memory Circuit: the light remembers the last-used output level, but only for outputs of 1000 lumens or below (excluding Strobe and SOS).

Battery & Charging

Uses a Fenix ARB-L21 series 21700 battery (3.6V, included). To replace: unscrew the light tail, insert the battery anode side (+) toward the light head, and screw the tail back on. Do not use 16340 batteries or LiFePO4 (18650, 3.2V) batteries — both are banned for this light; other 21700 Li-ion batteries should be used with caution.

To charge: turn off the flashlight, open the anti-dust cover to reveal the USB Type-C port, and connect the charging cable. The indicator glows red while charging and turns green when full — be sure to unplug and close the anti-dust cover once done. Charging from empty takes about 3 hours with a 5V/2A or higher adapter (this light does not support fast charging; only use a certified adapter). The light can be used while charging.

Battery Level Indication

Each time the light is turned on, the indicator shows the current battery level for 3 seconds.

• Green, on: saturated, 100–85%
• Green, flashing: sufficient, 85–50%
• Red, on: poor, 50–25%
• Red, flashing: critical, 25–1%

Protection Features

Intelligent Overheat Protection: at 60°C/140°F or above, the light automatically steps down output to cool down, and gradually restores the preset level once temperature drops.

Low-Voltage Warning: below 3.0V, the light downshifts to Eco. At Eco, the indicator blinks red rapidly and the light itself blinks for 20 seconds as a reminder; single-click the switch to stop the blinking and stay in Eco (usable for 30+ more minutes) until the battery needs recharging.

Care & Maintenance

• Do not disassemble the sealed head — this voids the warranty.
• Use only a high-quality battery.
• Remove the battery for storage if the light won't be used for an extended period.
• Unscrew the light tail or remove the battery during storage/transport to prevent accidental activation.
• Replace the O-ring with an approved spare if it shows wear, to maintain the waterproof seal.
• Clean battery contacts periodically with a rubbing-alcohol-soaked cotton swab if the light flickers or won't turn on.
