Hello everyone, I hope your all keeping safe and well.

I've recently bought a headlamp/headlight for outdoor chores ect, that I though would becoming with the two 18650 batteries it needs but didn't(guess who was the blind bat that didn't read the fine print?).

I've been looking for some from a reputable brand/company and frankly I feel like I'm in over my head, could anyone give me some pointers on what I should be looking for or be taking into consideration?
