Ordered a replacement 21700 battery for my G15. Great price for the specs. Surprised it showed up in less than 5 days. Excellent!

The high energy density means I carry fewer spares on multi-day trips, and the low self-discharge rate keeps it ready even after months of storage.

As an outdoor guide, I need batteries I can trust in extreme conditions

Lights are bright and last a long time, just had to change out the battery in one I bought in 2018

it was used for 6 months, still performs well
