Don't Trust your expensive thermal equipment to any other Power Source than Keepower! Don't let dead batteries jepordize your next hunt. Use Keeppower - Powerfull, Reliable, Safe!
This battery may fit other thermal products but is guaranteed to fit the following Thermal Products:
RIX LPR L6R
1. Protected 21700 Li-ion Rechargeable Battery
2. Typical Capacity: 6000mAh (Min. Capacity: 5900mAh)
3. Nominal Voltage: 3.6V/3.7V
4. Built-In Safety Circuitry
5. Protection Circuit (Against over charge, over discharge, over current and short-circuit.)
6. 4.2 volts max voltage and 2.5 volts cut-off voltage
7. Over 500 charge-discharge cycles
9. Battery Certification : UN38.3, IEC62133, CE, ROHS, MSDS, REACH, Regulation (EU) 2023/1542
Neither is better across the board, so use the one your device is built for. A 21700 is larger, about 21mm by 70mm, and holds more; this KeepPower is rated at 6000 mAh. An 18650 won't fit properly in a scope designed for 21700s, like the RIX LPR L6R.
KeepPower rates this cell for over 500 charge-discharge cycles. How many years that adds up to depends on how often you hunt, and you'll get the most from it by recharging soon after use and keeping it out of heat.
