BLF A6 questions

I bought one of the early BLF A6 Special Edition lights and think it is just about the favorite light for me. It came with an unprotected Sony 18650 and I will soon need a new battery.

Should I replace it with a protected 18650 and will the button top work in it?

Does the flashlight already have any low voltage protection built in?

Thank you for the advice.

If it ain’t broke… let me have a whack at it.

If the light has lvp onboard, I’d leave it (more resistance getting in the way), but if not, yeah, a nice GA might fir the bill.

It has lvp

Just tried it. A protected button top GA barely fits length wise. It will work, but compresses the springs to the max. It was made to use un-protected flat tops

it does have native LVP
it also steps down levels as capacity drops
ultimately it turns off
great light!
