Excellent Quality plus Last for Hours on my TM36
October 28, 2018
Always nice to have backup battery ready to go when doing search in Northern Wisconsin for night time wildlife. This battery is constructed very high quality standards and lasts for very extended use. I use in very low temperatures and battery does not mind 32F or less. I have already used at 10F and light was bright as ever. Thank You Battery Junction.
Great item

Purchased this for use with a TM11. Works great, charges in approximately 2-4 hours, makes the flashlight heavy but easier to charge than multiple batteries.
  • works well, easy to charge
  • Makes flashlight heavier

This battery pack does add considerable length. A small price to pay for the increased run times. It does come partially charged and should be fully charged before you use it. It would be nice to know what the run times are for this battery pack.
  • Increased run times and the ability to switch back to 18650s if needed.
  • Easy installation.

Nice addition to TM flashlights
January 6, 2015
The battery pack is a welcomed enhancement to the TM flashlights, but adds significant weight and size to the flashlight. The "Tiny" attribute no longer applies. My only suggestion is that a screw-on cap come with the battery pack. This would protect the end of the pack when not attached to a flashlight, and protect the stock battery compartment when removed from the flashlight.
  • Increased TM performance.
  • Significant weight and size penalty, but a reasonable tradeoff.

Nitecore NBP52 battery pac
November 4, 2014
I've got a couple of Tiny Monster lights and decided that I needed additional power sources for them. Battery Junction was running a sale, I had a discount coupon and the order was made.
A few days later the postman delivered the battery, 7 hours later it was fully charged using the 2amp charger. I can now use my TM36 for a few hours before I run out of juice.
  • Less costly than batteries and a holder
  • Would like higher capacity cells
