While durability and reliability are important to look for when choosing the best 18650 light, so are a few other things. The current 18650 flashlights are some of the most powerful flashlights ever made, with that said you are going to give up a little on portability due to the size of the battery. These are not keychain flashlights. When looking through the 18650 flashlight reviews you will want to pay attention to how much power and features the flashlights have, as well as what kind of light they are using. With the best single 18650 flashlight you are not going to have as much power as you will with the a multiple 18650 light because more batteries means more power. However, each style still has its uses. When looking at 18650 lights look for one that uses the current generation of LEDs rather than an older LED.
Why Choose 18650?
With all of the different types of batteries out there for flashlights, you might be wondering why you should choose the 18650 over something else like the CR123A. One of the best reasons we can think of is that the 18650 battery is a Li-Ion rechargeable battery rather than a single use, primary battery and with the right connection, you can easily charge them while you are on the go. Not only that, but a single 18650 battery is as powerful as 3 to 4 AA battery because of the higher voltage. The 3.7 volts put out by the 18650 provides you with about three times the amount of watt-hours for the same capacity. If you opt for a high capacity 18650, it can be almost 4 times as powerful as standard AA batteries. Another reason to opt for the 18650 is that it is the same length as 2 x CR123A batteries, which makes them easy to interchange. 18650 batteries have a great size to capacity ratio, and they have a high discharge and high capacity rate making them superior to similar sized batteries.
Favorite 18650 Batteries and Chargers
Something else to consider is the best 18650 battery for flashlights. As with other types of batteries , ou are going to run across numerous manufacturers, but they do not all have the same quality. When it comes to the best 18650 battery for flashlights you are going to want to stick with batteries that are built around the Panasonic NCR18650B 3400 mAh industrial core. Some people like buying unprotected Panasonic NCR18650B batteries trying to save a little money but we prefer the protected batteries. The best 18650 battery for flashlights that we have ever used is the Orbtronic 3400 mAh protected top button batteries, which are made specifically for flashlights.
Knowing the best battery to use is one thing, but what about when those batteries need to be charged. These Li-Ion batteries aren’t cheap, so the last thing you want to do is destroy them by using a horrible charger. In all of the chargers that we have looked at, we feel that the best is the Xtar VP2 Li-ion battery chargers. Not only is it one of the most advanced chargers, it is also available for a great price and comes with a USB connection that allows you t use the charger as a battery pack.
