Astrolux Ft03

Hi dear friend.I bought Astrolux Ft03 Cool White. But i have got one question about battery’s.
which one is best ?
I have got Sony VTC6. But i think i should use 21700 or 26650 which battery is best for long range ?

Thank you.

Welcome to BLF

Shockli 5500 26650 would be a good choice

There are other batteries discussed, you can also ask questions about the FT03 there…

Thank you for reply,I haven’t got any experience this forum.

I thought it has got FlashLight’s question.
I am sorry.

Do not be sorry.

Here is a link to the highest capacity 26650 battery:

I started a page to list battery compatiblity here:

well its not the highest really, there is the keeppower which is rated for 6000mah but shockli is still one of the best it seems for high drains vs capacity.

Keeppower uses the same cell inside. It’s just that KP overstates capacity while Shockli is very conservative with this cell.

Does it matter whether it is a button top or flat top? If it doesn’t matter, which might be better for other lights also? This would be my first 26650 battery or light.
