The i4000R is only compatible with NITECORE 21700 i Series batteries with an output over 15A and CR123/RCR123 batteries.
Note:
DO NOT attempt to use the i4000R to charge CR123/RCR123 batteries.
The i4000R is NOT compatible with conventional 21700/18650 batteries.
Battery Installation
Charging
Operating Instructions
Battery Installation nsert the battery(s) as illustrated and screw to tighten the tail cap. Note: After the battery insertion, the head power indicator will flash to indicate the battery voltage. Please refer to the "Power Indication" section of this manual for more details.
Ensure the battery(s) is/are inserted with the positive end towards the head. The product will not work if the battery(s) is/are incorrectly inserted.
DO NOT direct the beam to the naked eyes.
When the power level is low, please stop using the product and replace or recharge the battery to prevent damage to the battery.
When the product is kept in a backpack or left unused for prolonged time, please remove all batteries to prevent accidental activation or battery leakage.
DO NOT submerge the light into any liquid when it is hot. Doing so may cause irreparable damage to the light due to the difference of air pressure inside and outside of the tube.
Charging Function
The i4000R is equipped with an intelligent charging system. As illustrated, rotate the protective cover to reveal the charging port after inserting the battery, and then use the USB cable to connect an external power supply (e.g. a USB adapter or other USB charging devices) to the charging port to begin the charging process.
During the charging process, the tail power indicator will flash slowly to inform the user.
When the battery is fully charged, the i4000R will cease the charging process and the tail power indicator will become steadily turned on to inform the user.
When the charging status is abnormal (e.g. the battery is broken/inserted incorrectly), the i4000R will cease the charging process and the tail power indicator will flash quickly to inform the user.
When the light is on, connecting to a power source will automatically turn the light off. The light will return to its previous status and the tail power indicator will flash to show the battery voltage when it is disconnected from the power source.
The charging time for a 21700 Li-ion battery (5,000mAh) is approx. 4 hours 15 minutes. (Charged via the 5V/2A adapter)
Tactical Momentary Illumination
Half press and hold the Power Button to turn on the light momentarily. Release to turn it off.
On / Off
On: When the light is off, press the Power Button until a click sound is heard to turn it on. Off: When the light is on, press the Power Button until a click sound is heard to turn it off. (The i4000R has mode memory. When reactivated, the flashlight will automatically access the previous memorized brightness level or STROBE Mode.)
Brightness Levels
When the light is on, short press the Mode Button to cycle through the following brightness levels: ULTRALOW – LOW – MID – HIGH.
TURBO Brightness Level
When the light is on, press and hold the Mode Button to directly access TURBO of 4,400 lumens. Release to return to the previous status.
STROBE Mode
When the light is off, press and hold the Mode Button to access the STROBE Mode. Release to return it off.
When the light is on, triple press the Mode Button to access the STROBE Mode. Short press the Mode Button to return to the previous status.
Power Indication
When the battery is inserted, the head power indicator will flash to show the battery voltage (±0.1V).
When it is disconnected from the power source during the charging process, the tail power indicator will flash to show the battery voltage (±0.1V). For example, when the battery voltage is at 4.2V, the power indicator will flash 4 times followed by a 1.5-second pause and 2 more flashes. Different voltages represent the corresponding remaining battery power levels:
When the light is on, the head power indicator will indicate the remaining battery power.
Being steadily turned on indicates that the power is above 50%;
Flashing slowly indicates that the power is below 50%;
Flashing quickly indicates that the power is below 10%.
Note:
When using two CR123/RCR123 in series, the indicator will show the average voltage between the two batteries.
The batteries should be replaced or recharged when the output appears to be dim or the flashlight becomes unresponsive due to low power.
ATR (Advanced Temperature Regulation)
The integrated ATR technology regulates the output of the i4000R according to the working condition and ambient environment to maintain the optimal performance.
Maintenance
Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of silicon-based lubricant.

Note: The stated data is measured in accordance with the international flashlight testing standard ANSI/PLATO FL 1-2019, using 1 x 21700 Li-ion battery (5,000mAh) under laboratory conditions. The data may vary in real world use due to different battery usage or environmental conditions.
The runtime for TURBO mode is tested without the temperature regulation.
TURBO Availability: The TURBO level is only accessible when using a 21700 i Series battery with an output over 15A. It is inaccessible when using CR123/RCR123 batteries.
