21700 Flat Top Battery

These are very good, long lasting, powerful batteries.

So far (2 week review), the rechargeable batteries earn a 5-star review. They last a long time in the scope that I purchased, and they are easy to recharge.

So far these batteries are doing a great job. The 2 that showed up with my thermnight were at 20% and got me thru the learning of the scope. Cold weather will be the true test, but don't think I'll have any problems.

Hot little battery!

Great batteries!!!

First two extended range trips and its still 3/4 full.

The other guy I go out with hunting have 18650 I'm not having to change battery's out during the night.

Batteries obviously worked great and now I have extra batteries to switch out if need be. It’s nice they were offered for sale as many thermal optics manufacturers dont offer for sale!

I ordered some new batteries because the ones I had with the scope might’ve been ordered because they did not hold a charge very well. The new batteries work wonderfully. I’m very happy.

Came with low charge but charges fast
