>15A High Capacity Performance Battery

The next generation 21700 customized rechargeable battery from NITECORE, the NL2150HPi has an amazing 5000mAh capacity. This powerful battery has improved performance, and superior energy density compared to previous 18650 batteries. Specifically designed for the i4000R, the "i" series batteries can work with any other NITECORE flashlight that accepts 21700 batteries. An extra 21700 is a great backup battery to have on hand, as more electronic products and NITECORE flashlights will utilize this battery. The NL2150HPi can be charged using a traditional charger like a NITECORE UI1 or through the i4000R's built in charging port.

The NITECORE NL2150HPi comes with all of the safety features, quality engineering, and more that has made NITECORE a trusted brand for rechargeable Li-ion batteries. Your expensive electronics are safe paired with an NL2150HPi that features a built-in pressure relief valve, high temperature resistant design, and built-in safeguards to prevent surges. This protects you from overcharging, over-discharging, as well as short-circuits. The NL2150HPi is built with premium materials, such as nickel-plated stainless steel connectors for impact resistance, good conductivity, and resistance against oxidation. Safe and reliable, the NL2150HPi is globally insured and has multiple certifications for electronic use.

This 5000mAh rechargeable battery delivers powerful, long-lasting performance for i Series flashlights. Customers praised its "excellent capacity" and fast charging ("about a hour to fully charge"). However, some noted it's pricey and custom-designed, limiting compatibility with non-i Series lights. A few found minimal improvement over old batteries.

Essential addition.

I purchased a spare batterie to use while the other was charging. The performance seems so be very good. I figured it was worth the extra cost - you get what you pay for

Strong battery

Really not much to say at this point. The battery is for my Nitecore SRT7i 3,000 lumen flashlight which works very well! Haven't had either product long enough to make any kind of judgement as to longevity. The battery charged just fine so I threw a couple of 18650's at it that I knew were deficient. The charger called them "poor" so, it appears to be working.

Charged it up but it'll be a while before I figure out how good it is. Well, at least I have a spare, now.

Great batteries

I've been buying flashlights from Nitecore for a while now and have never been disappointed. I work in dark dirty places and need reliable lights. These batteries keep them running perfectly. They are good quality and recharge reasonably fast

The good and the bad

The battery works great I originally bought it for my p10ix because the original battery died and when I went to turn it on it didn't respond so I guess my flashlight is messed up Im now using the battery as a power bank

Batteries r fine BUT what happened to the F21i !?!

I use these NL2150HPl batteries for recharging all my devices while backpacking. I now have three of these 5000mAh batteries that work with the incredible F21i battery charger (from Nitecore). Sometimes you only need 5000mAh. For longer trips you may need 10000 or 15000. By using these batteries and the F21i, I have the advantage of flexibility over the NB10000 carbon power bank, where the F2li system is lighter and smaller than the NB10000 at 5000mAh, only slightly heavier at 10,000Mah, and I can take as many or as few batteries to suit my needs. I am sorely disappointed to have just invested good money in more batteries to find that Nitecore has wiped the F2li from its website. If my single F2li ever gets lost or breaks, I will have expensive, unusable batteries for my intended purpose. And no, I dint need the extra weight/bulk of a handheld flashlight. Please bring back the F2li!

Battery

What can I say--it's a quality 21700 protected battery. The downside--like so many manufacturers these days, this is a "custom" battery designed to work in a few Nitecore flashlights, rather than a generic that will work in a wide range of flashlights from various companies.

Works as Expected

It's a battery, it charges, it lights the flashlight, then I charge it again. When sitting not lighting or charging it is holding a charge, can hold a charge for a week at least then I use it again to light a flashlight.

Spare!

It is always a good idea to have a spare battery (or several). That way your flashlight will never be out of service while recharging.

I have four flashlights three I bought at a gun show and I am so impressed I bought one online from your store .I own a pest control company they are by far the best. I have tried a lot of flashlights the last 22 years nothing compares to nitecore.
